Compact laser line with a fan angle and Gaussian intensity distribution.
  • Line widths starting at 26 µm
  • Wavelengths 405 - 940 nm
  • Laser powers up to 86 mW

  • Micro Line Generator for small laser line widths and high power density in the focal plane


The laser diode beam source series 5LM+25CM has a fan angle of 8° or 15°. The intensity profile is Gaussian in line direction clipped by an aperture with an edge intensity of typ. 30%. The line width is constant along the laser line. Across the laser line the intensity distribution is Gaussian.  

Laser Micro Line Generators designed to produce lines with small line width. They have a small depth of focus (in this case the depth of focus is the Rayleigh range). Laser Macro Line Generators like the corresponding lasers of series 5LMM have common basic optical features but are designed to generate laser lines with an extended depth of focus.

The laser has integrated electronics for control of the laser output power. The output power can be controlled using modulation input ports (TTL and analog, in case of electronics type B TTL only) 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.
