产品特点
Equilateral dispersing prisms are used for wavelength separation applications. The three sides are of equal length. A light ray is twice refracted passing through the prism with total deviation denoted by qd in the figure below. Deviation is a function of refractive index, and hence wavelength. Angular dispersion Dqd is the difference in deviation for light rays having different wavelengths and varies with prism orientation.
