Low Noise Laser Macro Focus Generator with rotationally symmetric beam profile
The laser diode beam source type LNC-13MMC-S250-8+96CR-639-6-B21-M60-H-6 produces a rotationally symmetric laser spot with extended depth of focus. The beam profile is rotationally symmetric and approx. Gaussian.
The laser type LNC-13MMC-S250-8+96CR-639-6-B21-M60-H-6 produces a circular laser spot with extended depth of focus. The beam profile is approx. 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 the spot diameter increases proportionally to the working distance. A fine-adjustment of the distance between laser and target is recommended for fine-focusing.
