More info

Cadmium Selenide (CdSe) Crystal is a high-performance material with infrared transmission up to 24 μm and strong nonlinear optical properties, including a high nonlinear coefficient (d₃₁ = 18 pm/V). It is ideal for applications like difference frequency generation (DFG) and optical parametric oscillation (OPO) and can be pumped by 2 μm lasers to generate long-wavelength infrared radiation. Additionally, it is used in infrared optical components such as substrates and polarizers. For other applications, Cadmium Selenide is also available as Cadmium Selenide Lumps, Cadmium Selenide Evaporation Material, and Cadmium Selenide Sputtering Target. Heeger Materials (HM) provides high-quality Cadmium Selenide (CdSe) Crystals and related materials for advanced optical systems.
