Equilateral prisms have three equal angles of 60°, also known as dispersion prisms. Equilateral prisms are very suitable to be used in applications of wavelength separation for chromic dispersion. The equilateral prisms manufactured by Control Optics offer options of non-coating or single-layer MgF2 coating.
