Protected Silver: 450 nm - 20 µm

Four Diameter Options: 1/2", 1", 2", or 75 mm

Focal Lengths Range from 9.5 mm - 1000 mm

Seray' Protected Silver-Coated Concave Mirrors are designed for light collection, imaging, and focusing applications. These reflective optics focus light without chromatic aberration, making them especially suitable for broadband sources. 

These mirrors consist of a silver-coated N-BK7 substrate that features a protective SiO2 overcoat. They offer >95% average reflectance in the spectral range from 2 - 20 µm and >97% average reflectance in the spectral range from 450 nm - 2 µm. For applications near 780 nm, protected silver mirrors are significantly better than protected aluminum mirrors. With ≤λ/4 surface irregularity at 633 nm, these mirrors provide excellent image quality.
