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.
(1)EQUILATERAL dispersion prism
EQUILATERAL dispersion prisms have three equal 60° angles, which are made of optical materials with high difference of refraction indexes for different wavelength, such as the SF10.
