The laser diode beam sources series 13M/13MM produces an elliptical laser spot.

The laser diode beam source series 13M produces an elliptical laser spot with elliptical Gaussian intensity distribution. The laser diode beam source series 13MM produces an often circular (sometimes slightly elliptical) laser spot with extended depth of focus. The beam profile is approx. Gaussian. More precisely it has an elliptical intensity distribution clipped by a circular aperture.

Micro and Macro lasers
The lasers of series 13M and 5M 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 lasers have 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. 

RS232 interface
The lasers are equipped with an RS232 interface for laser control and data read-out. It provides e.g. control of ­laser power or allows to switch the laser ON and OFF and it allows to read and store critical data, like the hours of operation or the laser current for maintenance planning purposes.

Adjusting the working distance
For lasers of series 13M/13MM 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 in order to achieve minimal spot size.

These high quality lasers can e.g. be used for machine vision applications.
