Ion Beam Sputtered Coatings (IBS)
REO pioneered the commercial use of IBS Coatings in the late 1980’s. With 22 IBS systems in operation today, REO is home to the world’s largest concentration of IBS optical coating technology. Our IBS technology produces thin films with exceptionally low scatter and absorption along with high mechanical and environmental durability. Utilizing primarily metal oxide materials, REO uses IBS to produce films which function from the UV through the Mid IR (up to 6um).

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.

Superpolishing
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.
