Equilateral Prisms, also known as equilateral dispersive prisms, are optical prisms in the shape of triangles each that has three identical side lengths and 60°apex angles. Dispersion is the phenomenon when lights of different wavelengths travel through a media triggering different refractive indexes. The Equilateral dispersive prisms work according to this principle and are often utilized to break white light into a spectrum of different colors.
Hangzhou Shalom EO offers Custom Equilateral Prisms made from a wide assortment of materials, and high-refractive-index materials including N-BK7, UV Fused Silica, SF11, N-SF11, CaF2, MaF2, ZnSe, F2, N-F2, etc. Anti-reflection coatings with specified bandwidths are available to reduce the loss at the prism-to-air interface for high-refraction materials. Besides, we also provide Off-the-shelf Equilateral Prisms fabricated from SCHOTT F2, CaF2, UV Fused Silica.
