Hextek Lightweight Gas-Fusion Mirror 10x13x2.5 Coated for 248 nm
This is a Hextek lightweight gas-fusion mirror. It weighs 9.92 lbs, and measures 10" x 13" x 2.5" overall. Surface is coated with a high reflectivity dielectric coating that is optimized for a wavelength of 248 nm making it perfect for work involving KrF excimer lasers. However, the mirror could easily be over-coated with some other material. Peak to valley flatness is guaranteed to be better than 1/2 wave.
