Lasers for industry and science
About our resistent lasers for industry and science.Welcome to our websites and in the e-shop with laser technics.
Dear customers! On these websites, you will find a survey about our laser technics, which can serve mainly to the industry. Here we sell firstly the line lasers for saws, sawing machines and shears. Other laser types can be found here as well, their different output or colours. Since 2006 we specialize in lasers that can stand rough conditions in the industry, and lasers that master working in Sibirian winter or hot summer in Israel. We try to make our lasers endure even the worst treating, but still fulfil their functions even after the end of the guarantee. We wish you a pleasing purchase of our laser technics.
What will the using of a line laser bring to you ? You will be able to- to simplify the adjusting in the binding clamp for dividing and treatment of the material - to increase the accuracy of working and to save material waste - to quicken the machine working, to shorten the handling time, especially in mass production - to increase the security of working with machine shears and presses - to highlight imaginatively the firm sign, billboard or smaller constructions
Priority of our line lasers
Red lasers have a very low demand of electricity, by tens of mA – this makes it possible to connect the laser to the existing electricity source, e.g. the machine electronics. Thus it is not necessary to subjoin a further transformer and to adapt a switchboard.
Protection against the reversal of poles – the laser cannot be damaged by confusion of plus and minus poles.
Contain the regulated power supply – it is possible to supply directly from the transformer 24V or 12V with AC as well as DC voltage.
Coverage IP 65 – protects against dust and spraying water
Electroisolating protection of the inside electronics till 400V – network galvanicly separated from frame. If there is a voltage on the machine (e.g. by short), the laser cannot be damaged.
Vibration resistence – not containing any movable and releasable parts
Tappings are made in cables, not in separate wires. The length of cables can be precisely selected.
The models with connectors have a simple replacement service, thanks to the connector insertion.
The latest innovations of our lasers, their new types
If you need the laser which is convenient to designate the path to spray the road marking (lining laser) the selected laser and the reflective box with a special antireflective foil will surely come in handy for you. This box will allow you to monitor the end of the line in the daylight as well. With this utility you will be capable of making the straight lines with much lower efforts and with 1/3 saving of time necessary to make preliminary marking of the lines.
New holder on a square tube
since May we extend our portfolio of holders by the version with square tube of 20x20 mm. This holder is convenient where position needs to be changed frequently in one shifting direction. In a ripsaw, as an example. We hope that you will like the new holder and that it will make your work with our lasers simpler.
we extend our portfolio of magnetic holders with a variable joint. The holder is fitted with two strong neodymium magnets with a total pulling force of 54 kg. The magnetic base can be fitted directly with the holder fastening head or with one (or more) chain joint link(s). This assembly makes setting of the laser as needed comfortable.
Battery-pack Lithium with USB charging
starting from 2019 we extend our laser powering portfolio. We put up for sales the cordless charging device for our lasers with 3VDC power supply (it can also be used for 5VDC with different setting). This device contains a lithium 1200mA accumulator and it can be safely charged using Micro USB connector from any USB charger (5VDC). That is, from the phone charger and other devices. We believe it is more comfortable solution than replacement of conventional AAA batteries.
New material for making the plastic components
starting from June, 2018, we switch from ABS-T to PETG material in our 3D printing part production method.
It is a better material for our holders. It has higher strength and its printing in larger batches is more convenient. You will find their basic differences in a simple table. One month of testing in May made us convinced that you will be happy with the change. Upon the feedback of the users we had also altered the holder design. No breaking will occur where it might have taken place before... 8-)
We also cancelled optional sales of piece series of the holders in yellow colour. Interest in this option was not very high. Thus, we left the option of different colour variations except for black only for more than 10 pcs of holders.
Thank you for your comprehension
Improved universal shade for our lasers
a little upgrade is with us on daily routine, we have added a plastic new screw. Now it is possible to set the shades firmly. At the same time the plastic screw will not damage the surface of anodized tubule of laser.
Red lasers to the higher temperature conditions.
from June 2017 we have for you in offer new red lasers (650nm) 5mW with diodes for higher heat rating. These lasers manage the thermal range from -10°C to the 70°C (instead of common -12°C to the 45°C). Favourable is the fact that these diodes can be inserted in all models with 5mW red diode and we're able to create all combinations we have already used to. If you will wish such a diode, it is meanwhile necessary to write us about it. The price of laser will be a little higher... at the most however only 500, - CZK net of VAT/apiece. We're also able to place and compose cables with higher thermal immunity... it is also possible by agreement and drawing an offer.
Application on portable telephone or digitizer for calculation of laser radiating angle (for CAM/=android)
we have got an application for you, by the help of which you can yourselves after withdrawal from Google Play reckon correct characteristics of your laser.
Application will guide by the help of hints through all single steps. Nevertheless it is simple enough to understand it also without this help. We hope, this will help you easier pick out from ours relatively wide selection of optical members.
Universal shade for our lasers
we believe that you need not only our lasers, but also a lot of odds and ends which will make the use of them pleasant or easier. The shade is one of those trifles which we make for you. Where is necessary a line having an exact value of extent, it is impossible to use only radiating angle of laser. There is suitable to regulate the line exact using the shade. This help is just for such exact terms of tuning, though simple, created.
New extensive assortment of optical components
from 1. April 2017 we can offer you an extensive assortment of optical components to our lasers.
The selection is really wide. We shall have 16 optical systems in 3 kinds for linear lasers, from 5° to the 130° of radiating angle.
Newly we also have 4 cross optical systems in 2 kinds. You can find detailed specification in our well - arranged table. We believe, almost everybody can take his choice from this quantity.
Insulating girdle on laser to the frost
Dear customers,we have prepared for you a simple help which will improve possibilities for operation of lasers in exteriors during winter season, at temperatures below freezing point. IZN32 – insulating girdle/=sleeve for efficient lasers (diameter 32mm) with tempering. It enables quicker start of laser at the first trigger squeeze when it is frozen. It will also be easier to keep good inner climate in laser for its ideal operation in case of tempering.
Shorter version of efficient lasers with tempering
on the grounds of several consumers wish we have made a version of efficient laser with smaller extent
(with half extent - quasi 32x95mm + connector M12 with length 45mm). Electronics for power supply and for laser control we have inserted in box TEMPREG2, which is reserved for installation on DIN switch - board bar, best just beside the source. Lasers must have this control. Without this control it is not possible to operate the laser.
NOTICE: This version arose only as a demand on a smaller laser with the same characteristics. If there is enough place for laser on your machine, then it is surely the better solution to use a laser with integrated electronics.
New modulus for thermoregulator of laser TEMPREG2 on DIN bar
some time ago we have introduce into sales external thermo-regulator TEMPREG1. Some of you wished similar regulator also for installation to the distribution board of the machine. TEMPREG2 is intended just hereto. It will be simply attached on beside the breaker or the source on the DIN-bar. Wiring is simple and a detailed manual will completely guide you through herewith step.
This regulator worked up primarily for using it with lasers from the firm Peter Provazník – linear lasers, serve as supplement that makes it possible to ensure in heavy duty operating conditions of environment the safe prosecution of laser in allowed thermal tolerances. It is suitable to install this accessory to new lasers, because it is necessary to insert into laser an additional temperature-sensitive element already at production of the laser. It is also possible to use it behindhand, but only for scanning of temperature installation at point of sense organ - out of laser).
To this product there are ready also additional accessories. Possible are a suitable source or signalling of on-state on control panel of your machinery.
Cross-holder for two lasersDear customers,
there is now a new holder for cross-gripping of two lasers in our offer. It suits for determination of axial centre of a machine which changes all the time the height of material. For example a bench drilling machine or drain bushing for cutting water jet. It is possible to tilt down the heads and to mark, by the help of linear lasers, the accurate cross for marking of boring centre or beginning of cutting
Battery operated coaxial laser
from time to time turned up to us some fitters with a desire to have a perfect coaxial laser. It is especially needed for adjusting of metal cutting systems of several machines and alignment of them. E.g. big turning machines and its tailstock sleeve. Such a laser pointer is high accurate and coaxial. We have therefore elaborated an appliance and it is only enough to grip it into a chuck and to start simple adjustment.
Laser adapter for lightening “round the corner”Dear customers
surely have you or designers in your firm faced a problem where to place laser up, where the premises are narrow. We are bringing a solving now, at the beginning of year the 2016. Laser already doesn´t need to be placed so to shine like a torch hold in hand. Now you can fix it, using an extender, in a slot wide at least 50 mm and light abeam of laser. We believe, such an extender will find use on shearing machines or presses and all the places with space shortage.
Shade for decussate laser with emission regulation
we add a cover for decussate lasers. The cover makes it possible to changeover cover glass (added another glass) which can you buy in our place as well. It also serves for shaping of the laser beam and enables to create various patterns shading some of the cross arms. It also enables to reduce cross to the size you need. This supplement will at the same time stretch out the lifespan of your lasers protecting the primary objective covering optics against scratching.
přidáváme kryt křížových laserů. Kryt umožňuje výměnu krycího (přidaného druhého) sklíčka, které se dá u nás také zakoupit. Slouží rovněž k tvarování paprsku laseru a umožňuje vytvářet různé vzory zastíněním některého z ramen kříže. Nebo umožňuje zmenšit křížek na velikost kterou potřebujete. Tento doplněk zároveň prodlouží životnost vašich laserů tím, že hlavní krycí optiku ochrání před poškrábáním.
Rustless laser with cable without halogen
From September we have put in sales a new design of laser from stainless steel 1.4541 with cable clear of halogen. It is a product of laser advancement for customers with high demands concerning fire resistant laser as well as material resistance in aggressive surrounding. This laser is of course suitable to the food-processing industry too.
We are able to produce it with all optical systems commonly made in our firm and we are also able to add untypical optical elements.
We have been producing this type for supply potential 6-30V AC/DC (laser with converter), alternatively 5VDC and 3VDC.
Laser of course doesn´t need to have covering cap for stabilization of cable outlet, it can be shipped without it.I trust this new article will find connection to its discerning customers.
New cover of laser for dusty workplaces
we add to our offer a new cover for lasers working in dusty environment. It is also suitable for environments with an increased incidence of abrasive materials, or environments where are splashing various emulsions or ball-grains from welding, sawing or grinding. The cover enables exchange of the protecting (added) glass that can you also buy in our place. Two glasses are a direct part of a cover-glass packaging. This supplement will stretch out the life span of your lasers by protecting the main covering optics from scratching.
Rack for mounting of several lasersRack for holders made from ABS-plastic material in our 3D printer
we want to present our new series of holders made in our new 3D printing unit. The new rack for a set of holders will enable you to fix the entire series of holders, with 2 bolts M5/18 only, within the machine design. Nevertheless it enables the same or even more play for adjusting of lasers. But the most proper it is everywhere that laser shine in approximately in the same direction. E.g. at arising and other machines that work with more dividing tools. More information you will find in the reference to product.
New holders made from ABS-plastic material in our 3D printer
in this pre-Christmas time we bring to your attention a new series of holders made by our new 3D printer.
The holders are made from a tough ABS plastic material (optional colours) under application of a new sophisticated printing method of 3D print. From ABS is made e.g. the very popular Lego-set of blocks. ABS is a highly resistant and harmless material.
The holder is designed for fastening with 2 bolts M5/18mm (belonging to the set) within the machine frame. The holder enables the laser to be adjusted in 3 axes including lighting bellow itself as well as and upright above itself. It means there are included all the possible angels. It is supplied in such a completion as you can see in the photos.
We hope this holder will satisfy even the most exacting customers that need a stable and simply adjustable laser clamping for a very reasonable price. Laser adjusting step by step in single axis is simpler and more accurate.
Holder family is expected to enlarge by special items and sets enabling fixing of more lasers on one single holder.
The scope of 3D-printing is practically unlimited. We are ready to respond on eventual ideas and demands of our customers, namely very smoothly, prompt and cheap.
New module of temperature regulator for the laser TEMPREG1Dear Customers,
since May we can provide you with new solutions concerning the laser operation in difficult climatic conditions. One of them is an additional module controlling laser temperature.
This control device has been developed primarily for use with lasers of the company Petr Provazník – Line-Lasers. It serves as an accessory enabling to ensure secure laser operation within allowed temperature tolerances inside of hard environments (it is possible to install this accessory to new lasers only as it is necessary to insert into laser a supplementary temperature – sensitive element).
Regulator watches the adjusted allowable temperature interval for laser operation (this interval is set up during production for a concrete laser type). In case that the laser is too hot or too frozen there follows automatic disconnection to avoid laser damage. We trust that in workshops with a large range of various temperatures or at situating the laser in outdoor environment this regulator will reliably screen against operating error. This error is the most frequent laser trouble cause, it means in case of operating the laser at faulty temperature.
Cooling system with a “Peltier-link” PCHL60W
we would like to draw your attention to our new solution for laser operating in hot environments. Now we can offer you a cooling system working with a “Peltier-link”. This apparatus is able to keep any of your lasers up to the output of 10mW with connector M12 in an agreeable cool of 25° at the neighbourhood temperature of 60°C. (This apparatus has to be bought together with the laser intended to be used with. The laser has to be coupled with an appropriate sensor). Nowadays the laser can be already situated within warm environment and preserve its working life which steeply declines with growing temperature. It is also possible to operate the laser everywhere there where it wouldn´t be possible without cooling.
New family of lasers 3,5mW, 650nmDear customers,
since 28.1.2014 we introduce into sales a new laser family with 3,5mW diode in red (650nm) in red design. It will be produced in all 30 alternate designs as well as the lasers 1mW, 5mW and 10mW. We enjoy that the new family will cover the output gap between the lasers 1mW suitable for up to 1 m and 5mW suitable for up to 5 m as a maximum. 3,5mW lasers seem to be fit for applications with lightening up to 3 m. Thanks to suitable optics there can be achieved a thinner beam than in case of lasers 5mW.
New efficient industry laser 35mW, with interchangeable protecting optical system.Dear Customers,
since 27.1.2014 we put into sale a brand-new model of red laser 35 mW that expands the type range of the efficient red line-laser with exchangeable protecting optical system. There is concerned the laser product line for heavy industry and for rough working as well as climatic conditions.
Further, because of several appeals, we put again into sale the popular laser type 16 mV from the same type as the above mentioned laser 35mW.
We are sure you will enjoy the service of our lasers and they will be of good and reliable service to you over many years.
Laser with shielding, appropriate for chipping machines
In June we have prepared for you a special new type of shielded laser, designed especially for plasm chipping machines. This model has shielded electronics and a shielded incoming cable. The shielding protects the sensitive electronic parts against the electromagnetic and electrostatic pulses which brew up by the ignition of gas burners. We believe that these types will find their use.
Lasers with output 10mW 635mm
Dear business friends,
Since May 2012 we present another novelty. All red lasers that you could order in our firm in the output version 5mW can now be offered with 10mW output as well. This can be appreciated by the owners of smaller saw mills working in well-lit room conditions.
Laser with M8 connector
Since May 2012 we have brought out to market a new laser series with M8 connector. This series is smaller than that one with M12 connector. The diameter of this type is 16mm ( the connectors M12 – 18mm). Otherwise it is the same as the laser with M12 connector. But now we can offer you a smaller version which can be put even to that place which cannot be used in other types. More
A new laser series with transformer for supplying 6V to 30V
After a long checking, since February 2012 a new laser series has been presented on the market, with a new form of connection.
These lasers have a DC/DC inverter. This makes it possible to insert them to the feeding of 6V to 30V. This can be made by AC as well as DC voltage. These lasers have got a great advantage, on the contrary to the types with a fixed feeding value they run warm in a minimal way. It does not matter which feeding value will be chosen (within the respective range), the warming will not be substantially affected by it.Therefore they can be installed in places with a higher than usual temperature. With its own working, the laser will be warmed up max. by 2°C. Thus the laser can be installed on places with 43°C !! The light output of the laser will not be changed by the feeding value, it will equally blow by 6V as by 30V. We are sure that this series will be used both for its thermic resistance and for the variability of infeed.
Now also the possibility to choose the linking connector M12
Dear business partners,
When using high duty M12 lasers, it is now possible to choose not only the standard straight linking connector, but also that one bent by 90°. This connector has the same parameters as the straight one and there is no difference except of bending, but bigger lasers can be better installed into smaller room.
Now also the efficient industrial laser with changeable covering optics
Since July 1, 2011, a new type series has been presented for sale – an efficient red line laser with the exchangeable protective optics. These are lasers for basic industry, located in severe working and climatic settings. Even though these new lasers follow the types well proved through many years, they have been improved with some important changes.
The laser has available a new and unique solving of changeable protective optics. From experience it is known that before the laser working life itself can be finished, the protective optics is mostly damaged by scratching when carelessly cleaned. On some working places there are lasers that cannot be cleaned at all, e.g. scratching with stone dust or fine glued resin sawdust, and that´s why the protective optics can be exchanged very easily.One piece of spare glass slide is delivered with this laser, other glass slides can be bought any time for € 1,00 (without VAT).
The electronic components as well as the frame of the optic parts have been further improved. Now we are able to set your laser in many ways according to your special demands. We also enhanced the line precision and quality.
Thanks to changing some important suppliers and to producing some important components by ourselves, we can offer these lasers to you for far lower prices than till now.
A new laser series with a spiral cable inlet
Dear business friends,
We are coming with a new series of products. Since January 1, 2011, we present new lasers with spiral inlets to the market.
New lasers have 18mm diameter and 100mm length. It is not by coincidence that they are of the same dimension as our lasers with M12 cnnectors. The shielding will again be IP67, and therefore our lasers will be „waterproof“ as well, as you have found them so far.
The laser cables are 3m, 6m and 10m long, as usual. However, we are able to supply any length to 100m.
He new laser series with 12M connectors
Dear business friends,
I am greeting you in this New Year 2010 and I am coming with a new series of our products. Since February 1, 2010, we present new lasers with M12 connectors on market. Till now, the customers could only buy lasers with an cable outlet for supply connection. Now we will be able to fulfil the wishes of those customers who need to change the laser very quickly.
New lasers will be 100mm long and with 18mm diameter. They will be bigger, more robust, they have a larger refrigerating surface, and therefore they are adapted even to extreme temperature conditions as e.g. in African countries. The M12 4-pin-connector will be supplied by the Lapp Group Company. The shielding will again be IP67, and therefore our lasers will be „waterproof“ as well, as you have found them so far.
We are offering laser cables to these lasers too (3m, 6m and 10m long), as usual. However, we are able to supply any length to 100m.
All our products are purchased for a very fair price for you and your customers as well.
