Product description

G&H Germanium wafers are precision-manufactured from high-purity monocrystalline Germanium for use in infrared (IR) detection, semiconductor devices, and advanced photonic systems. These wafers offer excellent transmission in the mid- to long-wave infrared range (2–14 µm), making them ideal for IR detectors, thermophotovoltaic cells, and spectroscopic sensing.

Available in both intrinsic and doped forms (n-type or p-type), G&H Germanium wafers feature low dislocation density, excellent surface quality, and tight dimensional tolerances. They can be supplied in standard semiconductor-grade diameters with polished, lapped, or etched surfaces depending on downstream processing requirements.

With applications in aerospace, defense, medical diagnostics, and industrial sensing, Germanium wafers support high-sensitivity devices operating across a wide range of infrared wavelengths.
