Anamorphic Prism Pairs

TECHSPEC Mounted and Unmounted Anamorphic Prism Pairs

×
  • Converts Elliptical Beam to Circular
  • Anti-Reflection Coated for Common Diode Wavelengths
  • Mounted and Unmounted Versions Available

An anamorphic prism pair is used to expand a laser beam in one dimension. This makes it ideal for converting the elliptical beam shape of laser diodes into a nearly circular one. Mounting our unmounted anamorphic prism pair in the proper orientation will provide magnification ratios from 2:1 - 6:1. Designed at 650nm and broadband anti-reflection (BBAR) coated for 600 – 1050nm, it provides excellent performance at both 635nm and 670nm.

The center of the output beam is displaced 5.9mm from center of the input beam in our mounted anamorphic prism pair. The Dovetail Accessory Mount allows it to rotate with respect to the laser, simplifying bench-top mounting. The C-Accessory Mount allows our full line of C-Mount components to be used in conjunction with the mounted anamorphic prism pair.
