Filter Coatings

Filter Coatings

REO provides a diverse range of wavelength selective coatings for the ultraviolet, visible and infrared, including bandpass filters, long wave and short wave pass filters, notch filters, dichroics, trichroics, harmonic separators and even spatially variable components.  Our range of coating technologies means we can always deliver optimum performance/cost.  For example, we utilize ion beam sputtering (IBS) to deliver bandpass and sharp edge filters which have exceptional wavelength stability with respect to changes in ambient temperature and humidity. 


Our factory has been built and organized for optics, thin film coatings and assembly fabrication. Clean rooms, state of the art metrology and our laminar flow production areas for contamination controls are just the foundation of what we do to ensure excellence.
