Availability: eSource Optics VUV to UV Mirrors are supplied on a per order basis.  Lead-times can vary and are typically within ~4 weeks.

All eSource Optics Broadband VUV to UV Al & MgF2 Mirror Coatings offer excellent reflectance properties at the specific VUV through UV wavelengths listed below, with high average broadband reflectance throughout the Visible to NIR.  High Reflectance broadband VUV to UV mirror coatings are specifically designed for use in a variety of VUV to UV instrument and research applications including VUV to UV-based analytical instrumentation, DUV spectrophotometers & Ellipsometers.  For the VUV through the UV wavelength region, we supply % Reflectance curves with every Lot of mirrors supplied.  All eSource Optics VUV to UV Mirrors are measured on a Vacuum Spectrophotometer system capable of measuring VUV through 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 also offers standard VUV to UV Spherical Plano-Concave Mirrors  with our High Reflectance Broadband VUV to UV Mirror Coatings listed above on 0.5" (12.7mm), 1.0" (25.4mm) & 2" Diameter (50.8mm) Plano-Concave Spherical Mirror substrates with Concave Radii from 0.25 Meter up to 2.0 Meter.   Custom sizes and Radii also available, including custom Off-Axis Parabolic Mirrors.
