Green Machine Vision Collimator with elliptical Gaussian beam profile

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

55CM
The Laser Diode Collimators all have a Gaussian intensity profile. The 55CM/55CR produce collimated beams with Gaussian beam profile while maintaning the intensity profile of the laser diode - in this case elliptical.

Electronics
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. Optionally the lasers can be equipped with RS232 serial interface for laser control and data read-out.

Adjustment of collimation settings
The collimation can be adjusted by using a hex key for series 55CM/55CR. Please note that this affects beam parameters like collimated beam diameter and beam divergence.

Optional: Low Noise Version
The laser series 55CM/55CR are also available as a Low Noise version LNC-56CM/LNC-56CR. These lasers are low noise (typ. < 0.15 % of P_o* (RMS, Bandwidth < 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 beam diameters.  (* P_o is the maximum specified output power.)

These high quality lasers can e.g. be used for machine vision applications.
