Infrared Prisms
REO fabricates a wide variety of prism types utilizing substrate materials including fused silica, Si, Ge, ZnSe, ZnS, CaF2, MgF2, Cleartran and AMTIR. We specialize in components with high quality surfaces, minimal edge defects, large clear apertures, tight angular tolerances and low wavefront error. Carefully controlled fabrication and coating processes allow us to consistently deliver superior performance. A full suite of advanced metrology instruments enable us to achieve and verify arc second level angle accuracy.
High Precision Prism Assemblies
REO's high precision prism assemblies utilize novel adhesive free Activated Covalent Bonding (ACB) to enable the construction of compact beam multiplexing systems. REO prism assemblies are distinguished by their low transmitted wavefront distortion values (as low as λ/10 at 633 nm), beam deviation tolerances in the arc second range, and even the capability for precise control of output beam phase relationships. These precision assemblies are available from numerous substrate materials for applications in the ultraviolet, visible, or infrared and in sizes ranging from 3 mm to 25.4 mm.

Thermal Evaporation
Evaporative coatings are produced in a high vacuum chamber. Both metals and dielectric coating materials can be utilized with this technique. The coating material is heated either resistively or through electron beam bombardment until it vaporizes. The vapor then streams away from the source and recondenses on all surfaces that are in a line of sight with the source. Wide range of coating materials allow coatings from the deep UV, to the LWIR.

Thin Film Coating
Over 20 years ago, REO became the first company to commercially provide Ion Beam Sputtered (IBS) thin film coatings. Today, we have expanded our technology to produce the highest quality thin films performing a range of functions across the full optical spectrum from the deep UV (190nm) through the long wave IR (14um). With a total of 35 coating chambers in operation, REO’s ability to produce the highest performance, lowest loss, most durable thin films across the spectrum is unmatched in the world.
