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.
