Germanium Crystal Plate

Stanford Advanced Materials (SAM) manufactures and supplies Germanium crystal plates designed to achieve a predictable transmittance and a uniform refractive index. These crystal plates are used for blanks, windows, lenses and prism arrays with diameters up to 300 mm for single crystals and 380 mm for polycrystals.

Infrared single-crystal Germanium is used in infrared optical and laser systems with thicknesses ranging from 2 µm to 20 µm. Single-crystal Germanium is primarily applied in the production of Germanium transistors, given that the electron and hole mobilisation in Germanium exceeds that observed in high-speed circuits.
