REO maintains 14 Fizeau interferometers for accurate measurement of surface figure, utilizing several different configurations for both in-process and final product measurement of surface figure of flat and spherical surfaces. REO has interferometers at 633nm and 1064nm. These instruments normally have an absolute accuracy of approximately l/100. REO maintains interferometers with apertures of up to 150mm diameter, with lateral resolution of up to 100um.Learn More
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.
