Optical filter - 380 nm - 2.6 μm
![Research Electro-Optics]()
A diverse range of wavelength selective coatings are provided by REO for the infrared, visible and ultraviolet. This range includes long wave and short wave pass filters, notch filters, bandpass filters, dichroics, trichroics, harmonic separators and spatially variable components. Ion beam sputtering is particularly used to deliver bandpass and sharp edge filters which have superior wavelength stability. This is in respect to changes in humidity and ambient temperature.
REO provides high transmission filters, very broad passbands and spatially variable films. The highly durable products have exceptional environmental stability. REO offers high out of band blocking.
