Macro Line Generator with a fan angle


Laser line with a fan angle, Gaussian intensity distribution and extended depth of focus.
  • Line length: 21.8 mm
  • Line width: 148 µm
  • Wavelength: 685 nm
  • Working distance: 138 mm
  • Depth of focus: 68.7 mm
  • Macro Line Generator for extended depth of focus
Macro Line Generator for extended depth of focus


The laser diode beam source type 5LMM8-S150-1+55CM-685-24-H13-A8-C-6 has a fan angle of 8° and an extended depth of focus.

The intensity profile is Gaussian in line direction clipped by an aperture with an edge intensity of 14 %. The line width is constant along the laser line. Across the laser line the intensity distribution is approx. Gaussian.

The laser has integrated electronics type C 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.
