REO produces an extremely broad range of high reflector products, with a particular competency around precision components that combine low scatter and very high reflectivity. We use state-of-the-art superpolishing technology to fabricate flat, spherical and even cylindrical mirrors. Our extensive array of metrology instrumentation enables us to measure and verify virtually all aspects of mirror performance, including reflectance, polarization characteristics, retardance, surface figure, surface roughness, absorption, laser damage threshold, plasma durability and even cavity ringdown time.

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.

Laser Damage Testing
REO provides some of the highest laser damage resistant optics in the world and is committed to the highest possible standard for testing and qualification of these optics. With our own fully automated laser damage test capability, REO not only conducts routing production testing of our products, but also continuously advances the state of the art in understanding laser damage mechanisms and test methodologies.
REO’s primary test system is comprised of a ~20ns pulse length 1064nm laser induced damage threshold (LIDT) test system according to ISO 21254-2 or other similar test protocols.Learn More
Substrate surfaces polished with roughness measuring less than 1A rms are availble from REO. “Superpolishing” refers to processes that are designed to produce surfaces featuring exceptionally low scattering of light throughout the UV to IR wavelength ranges. These superpolished surfaces often demonstrate surface scattering levels lower than 1ppm (wavelength dependent). In terms of surface roughness, this typically means surfaces with significantly less than 1A rms, integrated over spatial scales from approximately 1 micron to 100 microns. Superpolished surfaces may be flat or spherical with a radius of curvature as short as 20mm.Learn More
Our core production starts with optical polishing, includes super polishing, IBS coatings, broad focused metrology, including in house LDT and concludes with our active active assembly production. REO cutting edge technology enables the optimum manufacture of our products.
