Dispersion prism is a glass block in shape of pentahedron with two non-active triangular surfaces and other 3 optically active surfaces .
Dispersion prism is a glass block in shape of pentahedron with two non-active triangular surfaces and other 3 optically active surfaces .The most typical dispersion prism is equilateral prism made of high difference of refaction indexes for different wavelengths . Dispersion Prisms are ideal for spectroscopy or laser tuning
