Laser Dispersing Prisms

  • Separate light by wavelength
  • They are made so that entrance and exit beams pass through at the Brewster Angle

Like Brewster Angle Windows, Laser Dispersing Prisms can be used inside the cavity of laser operating on very low gain laser transitions, where even slight reflection losses may be intolerable.

Custom fabrication also available: coating, cutting, edging, drilling according to your specification.
