Precision Optical is The Prism Master

Custom Prisms Custom Prisms For 65 years, Precision Optical has been at the forefront of manufacturing some of the most custom and demanding prisms in the world. While our expertise has grown to include catalog optics, large optical flats (up to 850mm), integrated optical assemblies , and custom thin film coatings (including IBS), our core passion has always been prisms.

From Dove and sharp edge roof prisms to penta and corner cube retroreflectors, we are your one-stop shop for custom prism configurations that meet your most stringent requirements. Need light-weighting? Our advanced CNC machines have you covered. Require extremely low surface or transmitted wavefront distortions? Our 34 continuous polishers, combined with state-of-the-art high-resolution interferometers and master opticians, are ready to deliver. At Precision Optical, we also excel in quantifying and certifying glass materials for striae, stress birefringence, and inhomogeneity, ensuring an ideal starting point for achieving minimal transmitted wavefront error, independent of the glass manufacturer.







Prisms, particularly those with challenging specifications and configurations, can be a significant challenge. This is true for many optical components in the precision optics industry. However, we excel in this area, thanks to our extensive array of equipment and instrumentation specifically geared toward manufacturing prisms. Over decades our prism manufacturing techniques have evolved, and when combined with our metrology capabilities, we can now achieve prism angular tolerances down to ± 0.2 arc second and prism surface form error down to 10nm PVr and 2nm RMS!  Traditionally known for our UV to SWIR capabilities, we have also embraced many IR materials over the years. We actively welcome opportunities to create custom prisms from CaF2, ZnS, ZnSe, Si, and Ge.

At Precision Optical, we don’t just meet expectations; we set new standards. Trust us with your most challenging prism requirements, and experience the precision and excellence that have defined our legacy for over six decades!  Contact us or email
