Our spherical plano-concave germanium lenses are mainly utilized to diverge a beam from the collimated mild resource, or to increase the focal duration of an optical system.
It is usually value noting that germanium is relatively much more brittle that silicon and for that reason ought to be tackle with care in the course of machining.
Germanium has many strengths, making it an appropriate material for fabricating spherical lenses and aspheric lenses for a variety of purposes in aerospace, defense, and infrared optics.
To discover more about Germanium Windows from UQG Optics, or any of our optical windows simply call us on 01223 420329 or e-mail our revenue staff at [email protected]

It’s also a good choice in case you’re scanning overhead vents or duct work, substantial-ability transmission towers which can be a length absent. The telephoto lens allows you to perform safely and securely from the bottom.

We produce and manufacture optical factors in the very best top quality which you can use in a number of fields of application, from laser material processing to biotechnology, professional medical technological innovation, protection and safety along with the semiconductor sector.
Curiously, on account of its related crystal construction to Diamond may be coated having a DLC layer (Diamond Like Carbon) which in addition to lessening the reflection on it’s area, adds a diamond robust protecting layer. Eventually Germanium is just not clear from the noticeable that may be valuable to concentrate on IR light-weight.
At Shanghai Optics we manufacture numerous types of germanium lenses with a variety of anti reflection coatings. Spherical plano-concave, p-convex, concave-convex and aspheric lenses are all obtainable in numerous types of measurements. We can also be equipped to accommodate special orders in case you need a dimensions, shape or AR coating.
Sharpening & coating: Our sprucing strategies produce Excellent amounts of flatness, surface roughness, and surface area quality. Germanium lenses typically require optical or anti-reflection coatings to enhance their performance and sturdiness.
They could be Employed in beam expanders, and can also be used to balance out aberrations which had been introduced by other lenses in an optical arrangement.
Germanium (Ge) is actually a shiny, hard aspect by using a Knoop Hardness of 780kg/mm2 making it, coupled with its much much better sister sapphire, the default applicant for purposes in which the atmosphere is probably going To place a website beating on the material.
