Abstract. Germanium/Zinc Sulphide (Ge/ZnS) single and multilayers are deposited by ion assisted electron beam deposition on Silicon substrates for applications in the 2-15 µm wavelength region. Refractive indices of Ge and ZnS thin films are extracted from measured reflectance and transmittance spectra. Several types of mid-infrared …
(cm-1 Germanium exhibits low absorption of infrared radiation in the usable wavelength range of 2 to 12 µm. The band gap of 0.67 eV in Germanium is responsible for the increase in absorption in the short wavelength region. The lattice (phonon) absorption bands are responsible for the long wavelength absorption. The absorption...

Attenuate IR radiation from 2 to 14 µm; Precision Germanium substrates; Spectrally neutral vacuum deposited reflective coating; Optimized for 2 ...
Download. Germanium is a high index material that is used to manufacture Attenuated Total Reflection (ATR) prisms for spectroscopy. Its refractive index is such that Germanium makes an effective natural 50% beamsplitter without the need for coatings. Germanium is also used extensively as a substrate for production of optical filters.
Germanium is stable in air and water, and is unaffected by alkalis and acids, except nitric acid. Applications. Germanium is an important semiconductor, mainly used in transistors and integrated circuits. They are often made from germanium to which small amounts of arsenic, gallium, or other metals. Germanium forms many compounds.

The FWHM (full width at half maximum) for germanium detectors is an energy function. For a 1.3 MeV photon, the FWHM is 2.1 keV, which is very low. High-purity germanium detectors (HPGe detectors) are the best …
The majority of germanium is used in optical systems. This is because Germania (GeO2) has good qualities for working with light and lasers. It is used in applications like cameras, fibre optics, and microscopes, and infrared optics. Camera Lenses – used in the manufacture of wide-angle camera lenses. It gives special properties to the glass.
The germanium Ge100_10 photodetector achieves a 3-dB bandwidth of 265 GHz at a d.c. photocurrent of 1.0 mA, which is an improvement of a factor of ~2.4 compared to ref. 10. This device even ...
QUEENS, NY— Death By Audio, the effects pedal company founded by Oliver Ackermann of A Place To Bury Strangers, announced today the Germanium Filter, a vintage console-style boost, fuzz, …
Common names include germanium-132 (Ge-132) and germanium sesquioxide. A 2012 study examined changes in rat fecal bacteria and found no correlation that Ge-132 accumulated in rat bodies by ...
The Germanium Filter, by our friends at Death By Audio, is uncharacteristically low on controls, but as noisy a pedal as the NYC company has gotten us used to. Inspired by the "ripped speaker" type of fuzz loved by the seekers of impure and corrupt tone, the Germanium Filter offers two knobs and an internal trim pot to push the …
As such, TECHSPEC Germanium (Ge) Windows should be used at temperatures below 100°C. Germanium's high density (5.33 g/cm3) should be considered when designing for weight-sensitive systems. The Knoop Hardness of germanium (780) is approximately twice that of magnesium fluoride, making it ideal for infrared applications requiring rugged optics.
germanium (Ge), a chemical element between silicon and tin in Group 14 (IVa) of the periodic table, a silvery-gray metalloid, intermediate in properties between the metals and the nonmetals.Although germanium was not discovered until 1886 by Clemens Winkler, a German chemist, its existence, properties, and position in the periodic system …

Features. Thorlabs' Ø1/2" and Ø1" Germanium (Ge) Plano-Convex Lenses are available with a broadband AR coating for the 7 µm to 12 μm spectral range deposited on both surfaces. This coating greatly reduces the high surface reflectivity of the substrate, yielding an average transmission in excess of 94% over the entire AR coating range.
The primary sources of worldwide germanium production are Zn-refinery residue and coal fly ash, with recycling of industrial scraps being the secondary source [12].Globally, the main producer of germanium is China, accounting for 80% of world production during 2012–2016 [7].Other producers are Russia, Finland, US, Japan, and …
