Applications of equilateral prisms are to disperse or break light into its spectral components. These prisms are available from Holmarc either uncoated or with single layer anti-reflection coating on the faces. AR coating helps to reduce polarization at the surface by increasing total transmittance. Broadband multi-layer anti-reflection coated prisms can be provided on special requests.
