Product Family Description

  • 120nm and 190nm Design Wavelengths
  • Average Reflectivity >85% Across Specified Range
  • Enhanced Metallic Coatings for Broadband Reflectivity through the Visible Region

TECHSPEC® Precision Ultraviolet Mirrors are ideal for most commercially available light sources and are offered in both Deep UV (DUV) and Vacuum UV (VUV) enhanced coating options. The DUV coating offers excellent reflection from 190nm to the long-wave infrared (LWIR), while the VUV coating has optimized reflection from 120nm to the LWIR. These mirrors are designed for 0° angle of incidence and feature an aluminum-based coating for low polarization sensitivity. TECHSPEC® Precision Ultraviolet Mirrors have an average reflectivity of greater than 85% across a specified range. The mirrors are available in diameters ranging from 5 to 50mm.

Note: The soft coating can be easily damaged by fingerprints and aerosols.
