The laser diode beam sources series LNC-5LT-2 produce a semi-telecentric laser line in the range of 2 mm line length. The line length is given on the 13.5%-level. The intensity profile is Gaussian in line direction. The line width is constant along the laser line. Across the laser line the intensity distribution is Gaussian. 
The lasers are low noise (0.1 % RMS,@<1 MHz) and operate mode-hopping free. Due to the reduced coherence length the speckle contrast is lowered. However this effect is smaller for smaller lines and spots.
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. 

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.
