Highly-specialized optical systems often require components that cannot be classified under the standard prism types. Unusual prism shapes, angles/beam paths, thin film coatings, or chamfers/flats and other features may bring into question the manufacturability of the optical components.

Since the company’s founding in 1959, Precision Optical has specialized in manufacturing custom optical components for the most demanding applications. Our facility is configured to allow flexibility in addressing our customers’ custom prism needs, from prototype units to large scale production. Our experienced sales staff collaborates with our engineers and manufacturing technicians to evaluate the feasibility of each prism design, and can offer advice on how to reduce costs while optimizing the performance of the custom prism. Our ISO 9001:2008 design-certified engineering team can assist in the design of custom prism configurations.
