Equilateral Dispersing Prisms

Equilateral Dispersing Prisms


 Equilateral dispersing prisms are used for wavelength separation applications. Deviation is a function of refractive index, and hence wavelength. Angular dispersion ∆θd is the difference in deviation for light rays having different wavelengths and varies with prism orientation.
