All UV Optical Bandpass Filters from 270nm to 326.1nm are available at select wavelengths in standard 12.5mm, 25.0mm, and 50.0mm Diameters. UV Optical Bandpass Filters from 270nm to 326.1nm are metal-dielectric-metal (MDM) design thin-film UV Bandpass Filters supplied as Unmounted and Open-Faced Filters.   Open-Faced UV Optical Bandpass Filters from 270nm to 326.1nm include a high purity UV grade Fused Silica substrate over-coated with the MDM filter coating. All UV filter substrates from 270nm to 326.1nm have a highly polished scratch & dig surface quality with less than ~5 arc minutes parallelism.  "FVN", "FNB" & "FBB" Optical Filters are available at other wavelengths from 193nm to 313nm upon request.

Open-Faced UV Optical Bandpass Filters from 270nm to 296.7nm are fairly soft and must be handled with due care. For added durability and protection from the environment, UV filters can be special ordered with a UV Fused Silica cover window that is edge sealed to the Open-faced filter.  For more information on covered & edge sealed  UV Optical Filters and/or UV filter peak wavelengths not listed below, please contact eSource Optics. UV Optical Bandpass Filters from 300nm to 326.1nm are multiple element filters and are only supplied edge sealed and mounted as 12.5mm, 25.0mm & 50.0mm Diameter Optical Filters.

All eSource Optics UV Optical Bandpass Filters are supplied with individual % Transmission Calibration Curves detailing normal incidence UV spectral performance characteristics.  UV Optical bandpass Filters are mainly used in UV light source applications requiring a narrow spectral bandwidth and a high signal-to-noise ratio.

optics, Science concerned with the production and propagation of light, the changes it undergoes and produces, and closely related phenomena. Physical optics deals with the nature and properties of light; geometric optics deals with the formation of images by mirrors, lenses, and other devices that use light. Optical data processing involves manipulation of the information content of an image formed by coherent (one-wavelength) optical systems. The study of optics has led to the development of devices such as eyeglasses and contact lenses, telescopes, microscopes, cameras, binoculars, lasers, and optical fibres (see fibre optics).

eSource Optics Ultraviolet (UV) Optical Bandpass Filters are available at specific peak wavelengths over the Ultraviolet wavelength range of 220nm to 320nm, within the UV-C & UV-B Short to Mid-wave Ultraviolet spectrum.  Both Narrow Very Narrow & Broad Bandwidth UV Optical Bandpass Filter designs are available and designated as "FNB" & "FVN" having a 10-25nm FWHM, and "FBB" having a ~50nm FWHM.
