Product Description
Features
- Protected Aluminum: 450 nm - 20 µm
- Four Diameter Options: 1/2", 1", 2", or 75 mm
- Focal Lengths Range from 9.5 mm - 1000 mm
Seray's Protected Aluminum-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 offer >90% average reflection in the spectral range from 450 nm - 2 µm and >95% average reflection in
the spectral range from 2 - 20 µm. They consist of an aluminum-coated N-BK7 substrate that features a protective SiO2 overcoat. With ≤λ/4 surface irregularity at 633 nm, these mirrors provide excellent image quality.
