Vacuum UV Broadband Filters

eSource Optics Vacuum Ultraviolet (VUV) Broadband Optical Filters are available at specific peak Vacuum UV (VUV) wavelengths as short as 130nm up to 214nm.

Broad Bandwidth VUV optical bandpass filter designs are available designated as "FBB" having a ~35-50nm FWHM. Popular Vacuum Ultraviolet (VUV) Analytical and Laser Lines are available in 10nm increments. Other Vacuum Ultraviolet (VUV) wavelengths are available upon request. Narrow Bandwidth VUV optical bandpass filter designs are also available designated as "FNB" having a ~20nm FWHM.

All VUV optical bandpass filters are available in standard 12.7mm, 25.4mm, and 50.8mm Diameters. VUV Broadband Optical Filters are metal-dielectric-metal (MDM) design thin-film VUV bandpass filters supplied as Unmounted and Open-Faced Filters. Open-Faced VUV Broadband optical filters are manufactured using high purity UV grade Fused Silica substrate for VUV wavelengths 170nm to 214nm. Open-Faced VUV Broadband optical filters are manufactured using high purity VUV grade MgF2, CaF2 & Quartz substrates for VUV wavelengths 130nm to 160nm. More information can be found on our Material Properties Page. Both VUV bandpass filter types are over-coated with the MDM filter coating. All VUV bandpass filter substrates are highly polished to a <20-10 scratch & dig surface quality with less than 3 arc minutes parallelism.

Open-Faced VUV Broadband optical filters are fairly soft and must be handled with due care. For added durability and protection from the environment, VUV Broadband filters from 170nm to 214nm can be special ordered with a UV Fused Silica cover window that is edge sealed to the Open-faced VUV Broadband filter. For more information on covered & edge sealed VUV Broadband Optical Filters and/or VUV Broadband filter peak wavelengths not listed below, please contact eSource Optics.

All eSource Optics VUV Broadband Optical Filters are supplied with individual Vacuum UV % Transmission Calibration Curves detailing normal incidence VUV-UV spectral performance characteristics. VUV Broadband Optical Filters are mainly used in VUV D2 light source applications requiring a fairly broad spectral bandwidth and a high signal-to-noise ratio.
