Description
Product Overview
The RIWETRA Germanium Single Wafer is a premium-grade, double‑sided polished germanium substrate designed for high‑performance infrared applications. Measuring precisely 10mm in diameter and 1mm in thickness, this wafer provides a clear, uniform optical window that maximizes transmission across the 2‑14 µm wavelength range. The wafer is fabricated from ultra‑high‑purity germanium crystal, ensuring minimal impurity levels and superior optical clarity. Its flatness and surface finish meet stringent industry standards, making it suitable for integration into spectroscopic instruments, thermal imaging systems, laser optics, and other precision scientific equipment. The product is supplied without any anti‑reflective coating, allowing users the flexibility to apply custom coatings if required for specific wavelength optimization.
Usage
Designed for a broad range of infrared‑focused environments, this germanium wafer excels in laboratory research, industrial quality control, and advanced manufacturing settings. In spectroscopy, the wafer serves as a reliable window for FTIR and Raman spectrometers, delivering consistent signal strength and low background noise. Thermal imaging devices benefit from the wafer’s high thermal conductivity and low emissivity, enabling accurate temperature measurements in aerospace, automotive, and medical diagnostics. Laser systems that operate in the mid‑infrared spectrum rely on the wafer’s durability and resistance to laser‑induced damage, ensuring long‑term stability even under high‑power conditions. Additionally, the wafer can be incorporated into custom optical assemblies, such as beam splitters, filters, and waveguides, where its precise dimensions and surface quality are critical for performance.
