Description

The laser diode beam source series LNC-13MM produce a circular laser spot with extended depth of focus. The beam profile is approx. Gaussian. More precisely it has an elliptical intensity distribution clipped by a circular aperture.

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 the spot diameter increases proportionally to the working distance.
A fine-adjustment of the distance between laser and target is recommended for fine-focusing.
