Pellin Broca Prism can be used to separate the harmonics of a laser beam or compensate for group velocity dispersion. The light enters and exits the prism near Brewster’s angle, which minimizes reflection losses in P-polarized light. Since the beam undergoes one total internal reflection before exiting the prism, the angle between the input and exit beams is 90° plus a small angle due to dispersion. The dispersion is less for longer wavelengths.
As Pellin Broca Prism is rotated about point A, the selected wavelength, which is deviated by 90°, is changed without changing the geometry or relative positions of the input and output beams.

This is the general standards we offer our customers, UNION OPTICS can supply other prisms meet your requirements, for detail information, please contact us.
