Filters

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.  We utilize ion beam sputtering, in particular, to deliver bandpass and sharp edge filters which have exceptional wavelength stability with respect to changes in ambient temperature and humidity. 

Think REO when you need:

• High transmission filters
• High out of band blocking
• Very broad passbands
• Spatially variable films
• Exceptional environmental stability
• High durability
