We can focus the laser beam differently if you wish. We can focus the laser so that at the desired distance (or range) the line or point is as thin as possible, as small as possible. Most of our lasers are manufactured with a beam angle of 70°. This is because the ratio of the angle to the amount of light incident on the area that forms the line is the most optimal. It is suitable for the vast majority of applications that our customers require from us.
However, we also commonly produce beam angles (line laser) of 35°, 45°, 70°, 85°, 110° with cylindrical optics, or 5°, 20°, 36°, 45°, 60°, 90°, 120°, 160° with bellows optics.
We can also offer you various unconventional light shapes, cross, target, various raster and other shapes with the help of diffractive optics.

Why don´t run after a big laser beam fan angle.

Here you can find a simple guidance instrument to determination of laser flaring angle you need. Reference to a detailed table you can find at the end of this chapter.

Angle Alfa - height v – line-length a
45° - 1m - 82cm
70° - 1m - 140cm
80° - 1m - 167cm
110° - 1m - 285cm
115° - 1m - 313cm

When lightening lengthways it is also possible, on condition that the laser is placed only a very small distance in front of the surface you need to lighten (Z=20cm), with a smaller angle to achieve even a longer distance (line-length a).

Angle Alfa - height v – line-length a
45°  - 1m - 129cm
50°  - 1m - 162cm
60°  - 1m - 273cm
70°  - 1m - 623cm
