Semi-telecentric Machine Vision Laser Line with uniform intensity distribution

The laser diode beam sources series 13LT/13LTM produce semi-telecentric laser lines with a uniform intensity distribution along the laser line.

13LT/13LTM
The laser diode beam sources series 13LT/13LTM produce a semi-telecentric laser line with 15 mm line length. The intensity profile is approx. uniform in line direction. More precisely, it is Gaussian clipped by an aperture with an edge intensity of typ. 80%. The line width is constant along the laser line. Across the laser line the intensity distribution is Gaussian for lasers of series 13LT and approx. Gaussian for lasers of series 13LTM.

Micro and Macro lasers
The lasers of series 13LT 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 13LTM have common basic optical features but are designed to generate laser lines with an extended depth of focus.

Electronics
The lasers have 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. 

RS232 interface
The lasers are equipped with an RS232 interface for laser control and data read-out. It provides e.g. control of ­laser power or allows to switch the laser ON and OFF and it allows to read and store critical data, like the hours of operation or the laser current for maintenance planning purposes.

Adjusting the working distance
For lasers of series 13LT/13LTM 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.

These high quality lasers can e.g. be used for machine vision applications, laser triangulation or laser light sectioning.
