eSource Optics offers a variety of High Reflectance broadband metallic Aluminum & Magnesium (Al & MgF2) VUV-UV Mirror Coatings with high reflectivity optimized at specific VUV to UV wavelengths.
All eSource Optics broadband VUV-UV Al & MgF2 mirror coatings offer excellent reflectance properties at the specific VUV-UV wavelengths listed below, with high average broadband reflectance throughout the Visible to NIR. High Reflectance broadband VUV-UV mirror coatings are specifically designed for use in a variety of VUV-UV instrument and research applications including VUV-UV-based analytical instrumentation, DUV spectrophotometers & Ellipsometers. For the VUV to UV wavelength region, we supply % Reflectance curves with every Lot of mirrors supplied. All eSource Optics VUV-UV Mirrors are measured on a Vacuum Spectrophotometer system capable of measuring VUV-UV reflectance as short as 120nm. The system is based on a calibrated Model VM-502 0.2 Meter Vacuum Monochromator with VUV enhanced 1200g/mm grating & Deuterium light source for very accurate VUV to UV wavelength measurements.
eSource Optics High Reflectance broadband VUV-UV mirror coatings offer superior reflectance properties as specified below, optimized for normal incidence. All eSource Optics broadband VUV-UV mirror coatings are available as complete VUV-UV mirrors per the sizes listed below; or on customer supplied substrates. eSource Optics also offers VUV-UV Spherical Mirrors as noted below.

All eSource Optics High Reflectance broadband VUV-UV Mirrors include a Flat (Plano-Plano) high purity UV grade Fused Silica or BK7 substrate over-coated with the VUV-UV Al & MgF2 mirror coating. All VUV-UV Mirror flat substrates are highly polished to a 40-20 to 20-10 scratch & dig surface quality with less than 5 arc minutes parallelism.
eSource Optics also offers VUV-UV Spherical Mirrors. We routinely provide 0.5" (12.7mm), 1.0" (25.4mm), 1.5" (38.1mm) & 2" Diameter (50.8mm) Plano-Concave VUV-UV Spherical Mirrors (or Plano-Convex) with typical Radius of Curvature from 0.1 Meter up to 10.0 Meter Concave Radii.)
