OpticsCalc Logo  OpticsCalc: Prism Refraction


The prism refraction pane computes the refraction of a ray through a prism. The input values are the index of the surrounding media n, the index of the prism material n', the angle of incidence of the input ray relative to the surface normal of the entrance face φ1 and the prism apex angle α. The pane then computes the beam deviation δ and the angle of the output beam relative to the surface normal of the output face fout. In addition the Prism Refraction pane also computes the angle of minimum deviation for the prism δmin as well as the input angle for minimum deviation φ1min.

This is an automatic computation pane. The results will update automatically as soon as a new input value is entered.

A Note On Units

All angles are in degrees.
