The laser diode beam source series 5MM produce a circular 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.
Laser Macro Line Generators designed to generate focus spots with an extended depth of focus. Laser Micro Focus Generators like the corresponding lasers of series 5M have common basic optical features, but are designed to produce spots with small spot size. They have a small depth of focus.
The laser has integrated electronics for control of the laser output power. The output power can be controlled using modulation input ports (TTL and analog, in case of electronics type B TTL only) 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.
