| Equilateral dispersing prisms are used for wavelength sparation applications. A light ray is twice refracted passing through the prism with total deviation denoted by ¦Á in the figure below. Deviation is a function of refractive index and hence wavelength. Angular dispersion ¦Â is the difference in deviation for light rays having different wavelengths, and it varies with prism orientation. | ||
