Equilateral Prisms

Kingwin Optics specializes in manufacturing custom equilateral prisms, which are triangular optical prisms with three identical side lengths and three 60° apex angles. These prisms are commonly used for dispersive purposes, such as separating a white light source into a spectrum of multiple colors. Depending on the substrate materials, equilateral dispersive prisms can be selected to break up different spectral regions. They function similarly to a diffraction grating but offer better brightness, greater endurance to power, and fewer issues with higher orders.

Kingwin Optics offers a wide range of custom equilateral prisms made from high-refractive-index materials, including N-BK7, UV Fused Silica, SF11, N-SF11, CaF2, MaF2, ZnSe, F2, N-F2, and more. The transmission range of these materials spans from ultra-violet to infrared. To reduce loss at the prism-to-air interface for high-refraction materials, anti-reflection coatings with specified bandwidths are available. These coatings also provide additional protection against chemical corrosion and other contaminants.

As a sophisticated supplier of optical components, Kingwin Optics is confident in providing a series of equilateral prisms with a wide selection of specifications. They are capable of delivering both high-precision prisms with tight geometric tolerances and standard-grade prisms for less challenging requirements. The surface qualities of their custom equilateral prisms range from 60/40 to 10/5 S/D, with flatness options of <λ/4, <λ/8, <λ/10@632.8nm. Additionally, they offer stocked equilateral prisms fabricated from SCHOTT F2, CaF2, and UV Fused Silica.
