Besides the Reflection Prisms, UPT also offers the Dispersion Prisms. The most typical dispersion prism is equilateral prism made of high difference of refaction indexes for different wavelengths. The dispersion prisms of special use are: Litrow prisms, Pellin-Broca prisms, Brewster prisms, Amici Prisms.
