Optical Prisms
Custom-Designed, Built to Spec
Custom optical prisms for beam deviation, reflection, dispersion, and image rotation. Every prism is manufactured to your exact specifications with angle accuracy down to 0.5 arcmin.
Types Available
- •Right-Angle Prism — 90 degree beam deviation and reflection
- •Dove Prism — Image rotation and inversion
- •Roof Prism — Image inversion with roof surface for binocular systems
- •Wedge Prism — Beam deviation and anamorphic expansion
- •Penta Prism — 90 degree deviation without image reversal
- •Equilateral Prism — Dispersion and wavelength separation
- •Custom Prisms — Designed to your specific requirements

We produce a full range of optical prisms including right-angle prisms, Dove prisms, roof prisms (Amici), Penta prisms, wedge prisms, Porro prisms, corner cubes, and custom prism geometries. We also manufacture prism assemblies and cemented components.
Prisms are used for beam deflection, image rotation, beam splitting, path folding, polarization manipulation, and dispersion. Typical applications include binoculars, periscopes, spectrometers, laser systems, and medical instruments.
Standard prisms have angular tolerances of ±3–5 arcminutes. Precision grade goes down to ±30 arcseconds, and high-precision grade can achieve ±5 arcseconds on critical angles. We provide interferometric angle verification for precision prisms.
We fabricate prisms from BK7, fused silica, CaF2, SF glass, N-BK7 equivalents, and other optical materials. For dispersive prisms we use high-dispersion glasses, CaF2, or fused silica depending on the wavelength range.
Yes. We apply aluminum, silver, gold, and dielectric reflective coatings on reflecting surfaces, and AR coatings on transmitting surfaces. We can also apply polarization-selective coatings for beam splitter prisms.
