Laser Micro Focus Generator with elliptical Gaussian beam profile


Laser spot with elliptical Gaussian beam profile.
  • Spot diameter: 0.007 x 0.016 mm
  • Wavelength: 685 nm
  • Working distance: 54 mm
  • Micro Focus Generator for small spot widths and high power density in the focal plane
  • With RS232 interface


The laser diode beam source type 13M-M60+55CM-685-41-H13-T12-CS-7 produces an elliptical laser spot with elliptical Gaussian intensity distribution.

The laser has integrated electronics type CS for control of the laser output power and serial interface (RS232). The output power can be controlled using the modulation input ports (TTL and analog) 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.
