Description

Laser diode collimators transform the divergent light of a laser ­diode into a collimated beam, while maintaining the Gaussian ­intensity distribution and the circular intensity profile.

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 collimation can be adjusted by using an eccentric key. Please note that this affects beam parameters like collimated beam diameter and beam divergence.
