Dual Wavelength Coated Ultra High Reflectivity Mirrors

The National Institute of Standards and Technology (NIST) is seeking information from potential vendors for the provision of dual-wavelength high-reflectivity mirrors. The mirrors will be used in primary acoustic measurement systems to support the mission of the Quantum Measurement Division. The minimum requirements for the mirrors include a reflectivity of 99.97% at 1560 nm and 390 nm, an angle of incidence of 0 degrees, and a substrate diameter of 7.75 mm. Vendors are asked to provide information on their company's capabilities, experience, and past performance in providing similar products or services. • The Quantum Measurement Division requires 12 high-reflectivity mirrors. • The mirrors must operate at wavelengths of 1560 nm and 390 nm. • The angle of incidence must be 0 degrees. • The reflectivity at 1560 nm and 390 nm must be 99.97% +/- 0.005%. • The optical losses must be 0.015% or lower. • The backside AR coating must be 390 nm + 1560 nm. • The substrate diameter must be 7.75 mm. • The substrate thickness must be 4mm - 6mm. • The frontside ROC must be 1 m. • The backside ROC must be Plano, optical polish.
