Spectral Systems’ Offerings For Off-Axis Mirrors

25 Aug 2022

Spectral Systems creates optical mirrors from on-axis, off-axis parabolic, ellipsoid, aspheric, flat, fold, faceted, and freeform. Our facility expertly polishes aluminum and diamond turns an array of substrates, including:  

  • Electroless nickel plated Al 
  • Electroless Ni plated stainless steel
  • Brass
  • Copper
  • Stainless steel

In partnership with our sister company, EMF, we offer a wide range of coatings for mirrors, including:

  • Aluminum 
  • UV protected aluminum
  • IR protected aluminum
  • Gold
  • IR protected gold
  • UV protected gold
  • Silver
  • Ultrafast enhanced silver
  • UV protected silver
  • IR protected silver

Spectral’s experience and equipment allow us to manufacture products to very accurate and precise tolerances backed by quality measurements. We offer off-axis parabolic mirrors measuring to an OAD (off-axis distance) of 150 mm from the optical axis. Our team manufactures on-axis aspheric and parabolic mirrors in diameters up to 320 mm. 

Our Standard Mirrors consistently measure <100Å RMS for roughness and 1λ form error/flatness. We are proud that our High-precision and Performance Mirrors offer <50Å roughness, ½ or ¼ λ form error/flatness. Final specifications always depend on the geometry and substrate required.

Spectral Systems delivers. Our team of engineers is ready to collaborate on your next project. Find out more at spectral-systems.com. Mastery of the IR.
