Anything about 100ºC is not suggested. By the time it reaches 200ºC it is nearly opaque whatsoever wavelengths. If you need a large temperature window, you’re superior suited to keep on with a cloth like MgF2, YAG or our old friend sapphire.
Germanium has several benefits, rendering it an appropriate materials for fabricating spherical lenses and aspheric lenses for various apps in aerospace, defense, and infrared optics.

1 cautionary detail to notice is that your germanium window is not going to respect remaining exposed to higher temperatures. Actually, there is an inverse marriage to temperature and transmission In regards to this materials. As your temperature goes up, the transmission properties will fall precipitously, a property often called thermal runaway.
Our in residence creation capabilities let us to offer swift direct-periods and high-quality product at aggressive selling prices. read more We manufacture both of those conventional evaporation dimensions and tailor made measurements on request...
The quantity of holes current may be diminished by escalating the amount of electrons by the addition of team V atoms (donors) on the Ge. This lowers resistivity. Excessive addition of donors causes extreme electron focus and greater absorption.
Much like how noticeable light digicam lenses certainly are a reliable glass condition, thermal digital camera lenses are strong Germanium. Just as glass is clear to obvious light-weight, Germanium is clear to your wavelength band of infrared radiation, which most thermal cameras use.
Firebird Optics manufactures most of these Home windows in various geometries, coatings and may also make lenses, prisms and many other optical components from germanium. Now back for your routinely scheduled programming…
Germanium is really a superior index product that is definitely used to manufacture Attenuated Overall Reflection (ATR) prisms for spectroscopy. Its refractive index is this kind of that Germanium will make a highly effective natural 50% beamsplitter with no have to have for coatings.
Both equally germanium and germanium oxide are clear to infrared radiation and so are commonly used in the manufacture of spherical lenses and Home windows for top performance infrared spectroscopes and thermal imaging methods.
UQG Optics ideal-sellers including Germanium Home windows can be obtained coated and uncoated in a variety of diameters and thicknesses.
Uncooked germanium substance is quite challenging but can even now properly be machined and polished into optical elements:
