Laser Grade Pellin-Broca Prisms, Optical Prisms

Pellin Broca prisms are constant deviation (90°) dispersing prisms. The input angle is arranged so that total internal reflection occurs at the internal face. This will provide a constant 90° deflection for the beam with dispersion. If the input beam enters the long side of the prism the longer wavelengths will be deviat

Pellin Broca prisms are constant deviation (90°) dispersing prisms. The input angle is arranged so that total internal reflection occurs at the internal face. This will provide a constant 90° deflection for the beam with dispersion. If the input beam enters the long side of the prism the longer wavelengths will be deviated less.

These prisms provide a convenient way to compensate for group velocity dispersion in ultra-fast lasers or to separate harmonic wavelengths in an incoming laser beam.
