Seray Protected Gold-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 >96% average reflection in the infrared spectral range from 800 nm - 20 µm. They consist of a gold-coated N-BK7 substrate that features a protective SiO2 overcoat. With low surface irregularity at 633 nm, these mirrors provide excellent image quality.
