Our germanium lenses Have got a higher refractive index—the highest refractive index amid readily available IR transmitters. Furthermore, it exhibits minimal chromatic aberration as a consequence of small dispersion.
fiveµm. This leaves germanium as the most beneficial and only choice for brutally difficult IR apps. This is often why you will see germanium windows and lenses serving in sites as inhospitable as outer Area, battlefields and in the middle of large-driven CO2 laser techniques. Additional on this afterwards.
The easiest method to cleanse the windows is to utilize either ethanol, isopropyl alcohol, methanol, reagent-grade acetone or lint-free of charge lens cloths. You may also use nitric acid but this content, even though alright for germanium can corrode other optics or mounts That could be nearby with your system.
To understand more about Germanium Home windows from UQG Optics, or any of our optical Home windows get in touch with us on 01223 420329 or electronic mail our revenue team at [email protected]

It is the Exclusive hardness of germanium that offers it its distinctive ruggedness; Ge provides a Knoop hardness of 780. It is a large density substance, at five.33 g/cm3, and allowances must be created more info for this fat When you are creating a bodyweight sensitive technique.
The top purpose is to provide germanium optics that meet up with or exceed the demanding necessities of various apps, from infrared thermal imaging and sensing to spectroscopy and laser techniques.
Thermal digicam lenses are created of Germanium due to the material’s unique Houses with regard towards the Infrared spectrum. Germanium is an element you can find while in the periodic desk and straight from character.
One particular very common circumstance we see germanium utilized is within high and small speed wind tunnels for jet propulsion research. Ordinarily, these windows are much bigger than inventory configurations reaching measurements in excess of 190-200mm.
Germanium includes a significant refractive index, so lenses made of Ge can target light-weight extra successfully and deliver bigger-resolution imaging for example thermal cameras, remote sensing, and night vision devices.
Equally germanium and germanium oxide are clear to infrared radiation and so are generally Employed in the manufacture of spherical lenses and Home windows for high efficiency infrared spectroscopes and thermal imaging methods.
Alternatively, You should utilize liquid CO2 from the specialized nozzle for cleaning although this needs added Value in phrases of equipment.
Germanium (Ge) is a shiny, really hard component having a Knoop Hardness of 780kg/mm2 which makes it, in addition to its far more robust sister sapphire, the default candidate for apps where the surroundings is probably going to put a beating on the material.
