Our germanium lenses Have got a substantial refractive index—the best refractive index amid available IR transmitters. It also exhibits minimum chromatic aberration on account of small dispersion.
Vast-angle lenses are perfect for residence inspectors that need to scan the skin of a house as you’ll be able to see the largest spot directly.
Germanium has superb thermal stability. It may withstand substantial working temperatures without degrading optical overall performance.
To see more details on Germanium Home windows from UQG Optics, or any of our optical Home windows connect with us on 01223 420329 or email our sales group at [email protected]
We provide plane, spherical, aspherical, cylindrical and toric mirrors for a wide range of purposes. They are created and made by Jenoptik to meet your unique demands. Additionally to standard substrate supplies, we also use metallic substrates.
Equally monocrystalline and polycrystalline Ge could be used for producing of optical factors. We develop Germanium lenses and windows for infrared thermal imaging applications and pyrometry (see our webpage Germanium windows and lenses for thermography).
Germanium’s transparency from the infrared wavelengths allow it to be a very important and broadly utilized product in infrared optics.
Comparable to how visible light digital camera lenses can be a stable glass condition, thermal digicam lenses are solid Germanium. Just as glass click here is transparent to visible mild, Germanium is transparent into the wavelength band of infrared radiation, which most thermal cameras use.
It may be Slash, polished and shaped into lenses and windows Utilized in infrared detector equipment and also infrared spectroscopes.
It's got very good transmission inside the 8 to fourteen µm array masking the thermal Infrared gentle, thus it's a material of choice for thermal and evening eyesight. What's more, it demonstrates a higher refractive index which enable significant open aperture angle optical part’s style and design.
Both germanium and germanium oxide are clear to infrared radiation and so are commonly Utilized in the creation of spherical lenses and Home windows for high performance infrared spectroscopes and thermal imaging units.
Alternatively, you can use liquid CO2 from a specialized nozzle for cleaning however this necessitates added Price tag in conditions of equipment.
These are rookie numbers and in many apps we’ll will need to spice up our window indicators through several coatings. Though This can be a drawback for optical windows this home is available in helpful for novel lens layouts and ATR optics where refraction is wished-for.
