Low Noise Micro Line Generator with a fan angle
The laser diode beam source type LNC-5LM8-S325+56CM-639-8-H18-A8-H-6 has a fan angle of 8°.
The intensity profile is Gaussian in line direction clipped by an aperture with an edge intensity of 44 %. The line width is constant along the laser line. Across the laser line the intensity distribution is Gaussian.
The laser has integrated electronics type H 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 lines and spots. 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.
