Laser Macro Focus Generator with approx. circular beam profile


Laser spot with approx. circular beam profile and extended depth of focus.
  • Spot diameter: 0.075 x 0.065 mm
  • Wavelength: 635 nm
  • Working distance: 233 mm
  • Depth of focus: 11.1 mm
  • Macro Focus Generator for extended depth of focus


The laser diode beam source type 13MM-S250-4+55CM-635-5-H10-T15-C-6 produces 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.

The laser has integrated electronics type C 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.
