Our germanium lenses Have a very superior refractive index—the highest refractive index among available IR transmitters. In addition it reveals minimal chromatic aberration resulting from very low dispersion.
Regrettably Germanium is reasonable to large temperature with degradation of its optical Qualities in excess of 100°C.
Germanium has quite a few advantages, making it an acceptable product for fabricating spherical lenses and aspheric lenses for numerous applications in aerospace, defense, and infrared optics.
Jenoptik manufactures hybrid components in optical content for infrared purposes. They are ideal for infrared aim lenses and programs, as well as for impression seize, goal detection As well as in infrared digicam know-how. You are able to choose from concave, convex, airplane, spherical and aspherical surfaces. Info Sheet
You can electronic mail the site proprietor to allow them to know you had been blocked. Make sure you incorporate That which you have been undertaking when this web page arrived up and also the Cloudflare Ray ID website identified at The underside of the webpage.
It's the Distinctive hardness of germanium that offers it its distinctive ruggedness; Ge incorporates a Knoop hardness of 780. It is just a substantial density substance, at five.33 g/cm3, and allowances needs to be made for this excess weight Should you be coming up with a pounds delicate program.
Germanium’s transparency in the infrared wavelengths help it become a vital and extensively utilised substance in infrared optics.
Coatings: Specialized anti-reflective coatings and treatment plans can even further increase the general performance of germanium optics by reducing reflection and absorption, increasing transmission, and expanding longevity.
Aspherical germanium lenses : built and employed for enhanced optical Houses and for programs that need pounds conserving. Germanium can be diamond changed into high surface area high quality aspheres.
Quantum cascades are employed by this sort of institutions because the Max Planck Institute of Quantum Optics in Garching to provide ribbons and strip buildings along with to generate new products to be used in health-related applications. Fairly amazing stuff!
Germanium and germanium oxide have an exceptionally large refractive index, meaning that for a few window apps anti-reflective coating is necessary.
UQG Optics finest-sellers including Germanium Windows can be found coated and uncoated in a number of diameters and thicknesses.
Uncooked germanium material is rather difficult but can nonetheless properly be machined and polished into optical elements:
