Description

The laser diode beam source series LNC-5LMM has a fan angle of 8° or 15° and an extended depth of focus. The intensity profile is Gaussian in line direction clipped by an aperture with an edge intensity of typ 30%. The line width is constant along the laser line. Across the laser line the intensity distribution is approx. 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. 

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.
