Frequently Asked Questions

The Broadband VUV to UV Optical Beamsplitters are designed to provide 40% to 50% average reflectance and transmission over the 170nm to 300nm VUV-UV wavelength range at a 45 degrees angle of incidence (AOI) unpolarized.

The Broadband VUV to UV Optical Beamsplitters are available in standard 25.4mm and 50.8mm diameters. Other sizes can be requested.

The Broadband VUV to UV Optical Beamsplitters are metal-dielectric-metal (MDM) design thin-film coatings supplied as unmounted and open-faced VUV-UV beamsplitters. They are manufactured using high purity UV grade Fused Silica substrate for VUV to UV wavelengths 170nm to 300nm.

The substrates of the Broadband VUV to UV Optical Beamsplitters are highly polished to a <=40-20 scratch & dig surface quality with less than 5 arc minutes parallelism.

The lead-time for ordering the Broadband VUV to UV Optical Beamsplitters is typically within ~3-4 weeks.
