Ultralow Loss Mid-IR Optics with Hybrid Crystalline Coatings

The National Institute of Standards and Technology (NIST) is conducting market research to identify alternative sources for Ultralow Loss Mid-IR Optics with Hybrid Crystalline Coatings. The project aims to detect trace impurities in gas-phase samples relevant to the semiconductor industry. The required optics should have a center wavelength between 4450 nm and 4550 nm, operate with continuous-wave (CW) mid-infrared (mid-IR) lasers, and comprise a hybrid crystalline and ion beam sputtered coating. • Center wavelength between 4450 nm and 4550 nm • Mirror hybrid coating reflectivity greater than or equal to 0.999970 at center wavelength • Mirror hybrid coating transmission less than or equal to 10 parts-per-million (ppm) at center wavelength • Coating diameter after transfer to substrate between 15 mm and 18 mm • Crystalline coating component comprises alternating stacks of GaAs and AlGaAs The project seeks to purchase six (6) units of these optics. Interested parties are requested to provide information about their company, products, and services, as well as feedback on the draft requirements.
