This calculator is designed to compute the dispersion characteristics of materials used in prism pairs. By selecting a material and inputting the wavelength, length, and prism angle, the system will automatically calculate and display relevant dispersion parameters.

Explanation of Beta Angle: Angle β is the angle between the reference ray and other rays propagating near the apices of the prisms. The reference ray travels from apex to apex of the prisms, and the angle β measures the deviation of nearby rays from this reference path.The angle β could be set to <0.1 degrees to start.
