Product Family Description

  • Enhanced Metallic Coating for High Reflectivity Across Deep UV (DUV) and Visible Spectra
  • 190nm Design Wavelength
  • <50Å RMS Surface Roughness

TECHSPEC® Ultraviolet Off-Axis Parabolic (OAP) Mirrors are coated with a DUV Enhanced Aluminum coating for excellent reflection from 190 – 900nm. To minimize scatter, these OAPs feature aluminum substrates and are diamond turned to have a surface roughness of <50Å RMS. Standard imperial diameters are available with multiple focal length options which range from 25.4 – 203mm. TECHSPEC® Ultraviolet Off-Axis Parabolic Mirrors are ideal for use in DUV ellipsometers, DUV Raman spectroscopy, or for general focusing of UV light generated by broadband light sources. To facilitate mounting and system integration, threaded mounting plate #47-111 (sold separately) which attaches to the base of these off-axis parabolic mirrors are available.

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