Laser Diode Beam Source series 13LNM
Laser Diode Beam Source series 13LNM with tools


Laser line with a fan angle, approx. uniform intensity distribution, and extended depth of focus.
  • Depth of focus 7 to 35 times larger than for corresponding Micro Laser Line Generator
  • Line widths starting at 14 µm
  • Wavelengths 635 - 940 nm
  • Laser powers up to 51 mW

  • Macro Line Generator for extended depth of focus


The laser diode beam sources series 13LNM have a fan angle between 0° and 16.8°, approx. uniform intensity distribution along the laser line and extended depth of focus. More precisely, it is Gaussian clipped by an aperture with an edge intensity of typ. 80% . Across the laser line the intensity distribution is approx. Gaussian. The line width is constant along 60% of the central area, outside this area the line width differs up to 30%.

The lasers of series 13LNM are Laser Macro Line Generators designed to generate laser lines with an extended depth of focus. Laser Micro Line Generators like the corresponding lasers of series 13LN have common basic optical features, but are designed to produce lines with small line width. They have a small depth of focus .

The laser has integrated electronics 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. Optionally the lasers can be equipped with RS232 serial interface for laser control  and data read-out.

For this laser type the working distance is fixed. A fine-adjustment of the distance between laser and target is recommended for fine-focusing in order to achieve minimal line width.
