Laser Macro Focus Generator
MacroThe laser diode beam source series 13MM 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 13M 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 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.
These high quality lasers can e.g. be used for machine vision applications.

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 (TTL only for electronics type B) or manually using the potentiometer.
Using the potentiometer you set the maximum output power of the laser. Turn the potentiometer clockwise for more power and anti-clockwise for lower power.
For all lasers with analog modulation input: The input for analog modulation allows applying an analog voltage Uanalog, which allows a linear control of the laser output power from approximately zero up to the maximum power given by the potentiometer setting.
Please refer to the manual for more details.
No, you are not allowed to take off the attachment optics. If you do so you can severely damage the laser as well as hurt yourself and others around you.
Each modification of the laser needs to be discussed with Schäfter+Kirchhoff first and is not to be done by the customer.
Often higher power lasers can be equipped with internal optical filters to reduce the laser power, which in consequence may mean a smaller laser class.
This option has the advantage, that you can still set the laser power using the potentiometer and - if the laser has an analog modulation input- use the full range of the analog modulation input for setting the laser power.
Please note, that reducing the laser power by potentiometer or analog modulation input so that it operates close to the laser threshhold negatively affects laser features like pointing stability, line width/spot size or state of polarization.
Please contact Schäfter+Kirchhoff for lasers with reduced laser power.
