Laser Diode Collimators 20C and 20P

Modular system for the customer assembly and alignment of laser diodes

A laser diode collimator transforms the divergent radiation of a laser diode into a collimated (parallel) beam. The beam profile is elliptical or circular and is defined by the beam characteristics of the laser diode. The parallel and perpendicular beam dimensions can be calculated from the beam divergence of the laser diode and the numerical aperture and focal length of the collimating lens.

Performance Features

  • Collimating lenses with focal lengths f’ 4–11 mm
  • Suitable for diodes of Ø 9 mm (Ø 5.6 mm with adapter)
  • With internal focussing mechanism
  • Collimator casing permits lateral x/y-adjustment of laser diode using screwdriver 9D-12
  • Frontal slot for fitting microfocus and micro line optics
  • Option: cable plug system 20CS/20PS for solderless contact of pins
