Laser line with a fan angle and approx. uniform intensity distribution.
  • Line widths starting at 40 µm
  • Wavelengths 405 - 940 nm
  • Laser powers up to 107 mW

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


The laser diode beam sources series 13LR have a fan angle of 12°, 25° or 40° with a constant line width and approx. uniform intensity distribution along the laser line.

The fine-structure is a chain of equidistant dots with a spacing of approx. the line width. The line width is constant along the laser line. Across the laser line the intensity distribution is Gaussian.

The lasers of series 13LR are 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 13LRM 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 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.

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.
