CdSe – Cadmium Selenide
Transparent 0.8 – 24 µm | Optimal performance 2.5 – 16 µm
CdSe crystal (Cadmium selenide) is crystalline material, usually orientation is wurtzite (Hexagonal). Cadmium selenide crystals are used in various middle infrared (MIR) applications, most commonly CdSe is used to produce infrared optical components and in CO, CO2 or tother infrared laser systems.
Over the years several crystal growing methods have been adopted to grow CdSe single crystal and poly-crystalline material. Chemical vapor transport, solid state re-crystallization, temperature gradient solution zone growing, high-pressure vertical zone melting are mostly used to achieve high quality CdSe crystal.
3photon can always give professional advice on crystal growing. After CdSe polishing the material can be coated upon request. In house coatings are modeled and deposited by experienced coating engineers.
