The laser diode beam source series 13M produce an elliptical laser spot with elliptical Gaussian intensity distribution.
The lasers of series 13M are Laser Micro Focus Generators designed to produce spots with small spot size. They have a small depth of focus (in this case the depth of focus is the Rayleigh range). Laser Macro Focus Generators like the corresponding lasers of series 13MM have common basic optical features but are designed to generate laser spots with an extended depth of focus.
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.
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.
