Silver Mirror, General Purpose, Borofloat, 50.8 mm, 450 - 12,000 nm

The 5123 General Purpose Silver Coated Mirror can be used over a broad spectral range with better than 95% reflectivity from 450 nm to beyond 12 μm. It's proprietary silver-based coating makes this 50.8 mm (2.0 inch) diameter mirror highly reflective from 0° to 45° and virtually insensitive to polarization. Protective dielectric coatings make it resistant to tarnish and oxidation. Plus it has minimal phase distortion, so it is useful for ultrafast-pulsed applications with Ti:Sapphire and other lasers.
