Low Noise Laser Micro Focus Generator with elliptical Gaussian beam profile
The laser diode beam source type LNC-13M-S250+56CM-640-14-H22-T15-H-6 produces an elliptical laser spot with elliptical Gaussian intensity distribution.
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 the spot diameter increases proportionally to the working distance. A fine-adjustment of the distance between laser and target is recommended for fine-focusing.
