UV Optical Bandpass Filters
220nm to 266nm

eSource Optics Ultraviolet  (UV) Optical Bandpass Filters are available at specific peak wavelengths over the UV wavelength range of 220nm to 320nm.  Both Narrow & Broad Bandwidth UV Optical Bandpass Filters designs are available and designated as "FNB" having a 20nm FWHM, and "FBB" having a 35-50nm FWHM. 

All UV Optical Bandpass Filters are available in standard 12.7mm, 25.4mm, and 50.8mm Diameters. UV Optical bandpass Filters are metal-dielectric-metal (MDM) design thin-film UV bandpass filters supplied as Unmounted and Open-Faced Filters.   Open-Faced UV Optical Bandpass Filters include a high purity UV grade Fused Silica substrate over-coated with the MDM filter coating. All UV bandpass filter substrates are highly polished to a 20-10 scratch & dig surface quality with less than 3 arc minutes parallelism.

Availability: eSource Optics UV Optical Filters are supplied on a per order basis; lead-time is typically within ~3-4 weeks.


Open-Faced UV Optical Bandpass Filters are fairly soft and must be handled with due care. For added durability and protection from the environment, UV Optical Bandpass 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.

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.

For more information on UV Optical Bandpass Filters, please refer to our VUV-UV Optical Filter Information Page
