dispersing prisms |
|
 This is a dispersing prism cut in half.
The desired beam enters the hypotenuse, reflects from a coated rear surface and
exits parallel to the entering beam. This is especially useful for multi-wavelength
visible lasers to select output wavelength.

Also called images rotors, a dove prism rotates an image about the beam axis by an
angle of rotation of the prism.
The DPD series is designed for use at 632.8 nm. Other wavelength designs are
available by special order.
