Compact Laser Micro Focus Generator with elliptical Gaussian beam profile


Compact Laser spot with elliptical Gaussian beam profile.
  • Spot diameter: 0.048 x 0.156 mm
  • Wavelength: 520 nm
  • Working distance: 317 mm
  • Micro Focus Generator for small spot widths and high power density in the focal plane


The laser diode beam source type 5M-S325+55CM-520-56-O11-A7.5-P-6 produces an elliptical laser spot with elliptical Gaussian intensity distribution.

The laser has integrated electronics type P with micro-controller 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.

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.
