Equilateral prism


He Rui optics' equilateral prism is an optical prism primarily used for applications involving the separation of wavelengths. This prism has three equal-length sides, and when light passes through it, it undergoes two refractions, with the total angle of refraction denoted as qd. The angle of refraction is a function of the refractive index and, therefore, also depends on the wavelength.

An equilateral prism has minimal reflection loss when light enters parallel to the prism’s base, a condition known as minimum deviation. Minimum deviation occurs when the angle of incidence and the angle of emergence for the incoming light and wavelength are equal (both angles are measured relative to the surface normal). Anti-reflective coatings help to reduce polarization at the prism’s surfaces, thereby increasing overall transmission.
