Description
The Laser Diode Collimators type LNC-56CR-450-26-O06-A7.5-HP-4 transforms the divergent light of a laser diode into a collimated beam, while maintaining the Gaussian intensity distribution and the elliptical intensity profile.
The laser has integrated electronics type HP with micro-controller for control of the laser output power. It is a low noise laser source (0.1 % RMS,@<1 MHz) with reduced coherence length and operates mode-hopping free. Due to the reduced coherence length the speckle contrast might be lowered. Please note that this effect is smaller for smaller beam diameters. 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 a hex key. Please note that this affects beam parameters like collimated beam diameter and beam divergence."
