Xihu District, Hangzhou, Zhejiang Province, China
Germanium (Ge) Windows
Germanium (Ge) Windows
Features: • Stocked and custom Germanium (Ge) windows available • Maximum diameter 300mm • Broad wavelength range covering 2000-16000nm, excellent for IR applications • Coating options: DLC coating, AR@3-5μm, AR@8-12μm, BBAR@3-12μm Germanium Windows are ideal for infrared spectrum applications for its broad transmission range and opacity in the visible portion of the spectrum. Germanium is commonly used in infrared (IR) thermal imaging systems operating in the 2 µm to 14 µm spectral range, and covers both the LWIR and MWIR spectrum. Ge windows are relatively more rugged than other infrared (IR) materials, it is often used as protective windows for thermal cameras, or the substrates for long-pass filters for wavelengths above 2000nm. Germanium also has the virtues of high chemical inertness and low chromatic aberration. But germanium would begin to become opaque in the IR spectrum when the temperature rises above 90℃, one should take caution when it is used in high-temperature applications. Hangzhou Shalom EO offers both off-the-shelf and custom Germanium Windows, the maximum diameter is 300mm. For the off-the-shelf versions, the specifications and transmission curves after coating are all listed individually. Because Germanium has a considerably large refractive index (about 4.0 at 11000nm), AR coatings are crucial to ensure high transmission. Coating options available include DLC (Diamond Like Carbon) coating, AR@3-5 micro, AR@8-12 micro, and BBAR@3-12 micro, Shalom EO is capable to fabricate the Germanium optical windows with the precision and coating sets according to your requests.
