eSource Optics Broadband VUV-UV Optical Beamsplitters (BBVUVBS) are Metallic VUV-UV broadband beamsplitter optical coatings that are designed to provide 40% to 50% average Reflectance and Transmission over the 170nm to 300nm VUV-UV wavelength range @ 45 degrees Angle of Incidence (AOI) Unpolarized.

eSource Optics Broadband VUV-UV Optical Beamsplitters (BBVUVBS) are available in standard 25.4mm and 50.8mm Diameters. Other sizes are available upon request.  eSource Optics Broadband VUV-UV Optical Beamsplitters (BBUVBS) are metal-dielectric-metal (MDM) design thin-film coatings supplied as Unmounted and Open-Faced VUV-UV Beamsplitters. Open-Faced Broadband VUV-UV Optica Beamsplitters (BBUVBS) are manufactured using high purity UV grade Fused Silica substrate for VUV-UV wavelengths 170nm to 300nm. All VUV-UV Optical Beamsplitters (BBVUVBS) substrates are highly polished to a <=40-20 scratch & dig surface quality with less than 5 arc minutes parallelism.
 

All eSource Optics Broadband VUV-UV Optical Beamsplitters (BBVUVBS) are supplied with individual Vacuum UV % Reflection/Transmission Calibration Curves detailing 45 degree (unpolarized) VUV-UV spectral performance characteristics. Broadband VUV-UV Optical Beamsplitters (BBVUVBS) are mainly used in VUV-UV light source and low power applications requiring nearly equal separation of Reflected and Transmitted broadband VUV-UV wavelengths.
 

 
eSource Optics also offers Vacuum UV Otical Beamsplitters from 120nm to 240nm on a custom basis upon request.
