Description

The laser diode beam sources series 13MM and 5MM produce a circular laser spot. They have different intensity distributions/beam profiles.

13MM and 5MM
The laser diode beam source series 13MM and 5MM produce a circular laser spot with extended depth of focus. More precisely it has an elliptical intensity distribution clipped by a circular aperture.The beam profile is approx. Gaussian

Macro lasers
The lasers of series 13MM and 5MM are Macro Focus Generators with extended depth of focus.

Electronics
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. Optionally the lasers can be equipped with RS232 serial interface for laser control and data read-out. Please note that the compact version 5M has different electronic features and is not available with RS232 interface.

Adjusting the working distance
For lasers of series 13MM and 5MM 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.

Optional: Low Noise Version
The laser series 13MM is also available as a Low Noise version LNC-13MM (Macro). These lasers are low noise (typ. < 0.15% of Po (RMS, Bandwidth < 1 MHz)) and operate mode-hopping free. Due to the reduced coherence length the speckle contrast is lowered. However this effect is smaller for smaller lines and spots. (Po is the maximum specified output power.)

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