VariFi (TM) Linear Variable Filters
REO manufactures spatially variable response coatings, in which the center wavelength of operation changes with position in a linear manner over the surface of the optic. REO has developed a unique, proprietary, volume scalable technology which enables cost effective production of linearlyvariable filters over a wide range of sizes. These filters are available in the visible, near infrared, and mid-infrared spectral ranges and can be delivered on a variety of substrate materials.

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.

Learn MoreSpectral Metrology/Laser Photometry
REO maintains an extensive set of lasers for metrology, covering more than 30 wavelengths and bands between 244nm and 10.6um. A range of standard and proprietary measurement techniques allows us to characterize reflectivity, transmission, polarization extinction, retardance and other functional characteristics across all angles of incidence.
Spectrophotometers, both dual-beam and FTIR, cover a wavelength range from 180nm to 20um, with a large number of fixtures to accommodate various sizes and geometries over the full range of incident angles.
