Compact Micro Line Generator with a fan angle



Compact laser line with a fan angle and Gaussian intensity distribution.
  • Line length: 12 mm
  • Line width: 41 µm
  • Wavelength: 785 nm
  • Working distance: 78 mm
  • Micro Line Generator for small laser line widths and high power density in the focal plane
Micro Line Generator for small laser line widths and high power density in the focal plane


The laser diode beam source type 5LM8-S88+25CM-785-86-Q06-A8-S-6 has a fan angle of 8°.

The intensity profile is Gaussian in line direction clipped by an aperture with an edge intensity of 5 %. The line width is constant along the laser line. Across the laser line the intensity distribution is Gaussian.

The laser has integrated electronics type S for control of the laser output power. The output power can be controlled using the modulation input ports (TTL and analog) or manually using the potentiometer.

The working distance can be adjusted by adjusting the focus setting. Please note that beam parameters like line length and line width increase proportionally to the working distance.

A fine-adjustment of the distance between laser and target is recommended for fine-focusing.
