The 13LT Series from Schäfter + Kirchhoff GmbH are Semi Telecentric Laser Micro Line Generators with an output wavelength from 405-940 nm. They provide an output power of up to 67 mW. These lasers produce semi-telecentric laser lines that are 15 mm in length and have a constant line width of over 12 µm. The laser line produced is a Gaussian intensity distribution clipped by an aperture with an edge intensity of 80%. The output power can be controlled using the modulation input ports (TTL and analog) or manually using the potentiometer. They can be optionally controlled with an RS232 serial interface for laser control and data read-out. These lasers have a fixed working distance hence, minimal line width can be achieved by fine adjustment of the distance between laser and target. They are ideal for machine vision, laser triangulation, and laser light sectioning applications.
