Filters
REO provides a diverse range of wavelength selective coatings, including bandpass filters, long wave and short wave pass filters, notch filters, dichroics, trichroics, harmonic separators and even spatially variable components. Utilizing ion beam sputtering, we deliver bandpass and sharp edge filters which have exceptional wavelength stability with respect to changes in ambient temperature and humidity.
Linear Variable Filters
Our custom linear variable filters offer a compact, cost effective solution for a variety of sensing applications. These spatially variable filter coatings, in which the center wavelength of operation changes with position in a linear manner over the surface of the optic can be applied to substrates as small as 1mm. REO has developed a unique, proprietary, volume scalable technology which enables us to manufacture filters in the visible, near infrared, and mid-infrared spectral ranges.
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).

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.

Spectral 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.
