Semi-telecentric Macro Line Generator


Semi-telecentric laser line with constant line length of 4.3 mm and extended depth of focus.
  • Line length: 4.3 mm
  • Line width: 46 µm
  • Wavelength: 640 nm
  • Working distance: 39 mm
  • Depth of focus: 7.13 mm
  • Macro Line Generator for extended depth of focus


The laser diode beam source type 5LTM-50-11+55CM-640-18-H22-A8-C-6 produces a semi-telecentric laser line with 4.3 mm line length. In this case the line length is given on the 13.5%-level. The intensity profile is Gaussian in line direction and the line is truncated at 4.8 mm. 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.

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.
