Equilateral prisms. Custom IR equilateral prisms

Manufacturer of equilateral prisms made of CaF2, IR Fused Silica, Si and ZnSe. Equilateral prisms feature three equal 60 angles and are often referred to as dispersing prisms. These prisms are ideal for wavelength separating applications. Deviation is a function of refractive index, and hence wavelength. Our Equilateral Prisms are available uncoated or with a anti-reflection coating.
