Vacuum UV Optical Filters

eSource Optics Vacuum Ultraviolet (VUV) Optical Bandpass Filters are available at specific peak Vacuum UV (VUV) wavelengths as short as the 122nm Lyman Alpha line up to 214nm, within the UV-C Short-Wave Ultraviolet spectrum.

Narrow Bandwidth VUV Optical Bandpass Filter designs are available designated as "FNB" having a ~20nm FWHM. Extra Narrow Bandwidth 121.6nm Lyman Alpha VUV Optical Bandpass Filter designs are available designated as "FXB" having either a ~10nm or ~15nm FWHM. Popular Vacuum Ultraviolet (VUV) Analytical and Laser Lines are available including 122nm Lyman Alpha line, 155nm Carbon IV (C IV) line, 158nm Fluorine (F) Laser line, 172nm Xenon (Xe) Laser line, 184.9nm Mercury (Hg) Lamp line, 193nm Argon Fluoride (ArF) Laser line & 214nm Zinc (Zn) line. Other Vacuum Ultraviolet (VUV) wavelengths are available upon request. All VUV Optical Bandpass Filters are available in standard 12.7mm, 25.4mm, and 50.8mm Diameters. Very Narrow Bandwidth VUV Optical Bandpass Filter designs are available at select 214nm and longer VUV to UV wavelengths designated as "FVN" having a ~10nm - 15nm FWHM in both a 25.0mm & 50.0mm Diameter size. "FVN" type Optical Filters are available at other wavelengths from 214nm to 313nm upon request.

Broad Bandwidth VUV Optical Bandpass Filter designs are also available designated as "FBB" having a ~35-50nm FWHM .
