Our aspheric lenses have a more sophisticated entrance. The curvature progressively improvements as you progress from the center with the lens out to the sting. Our aspheric Ge lenses are most frequently utilized to remove spherical aberration in an optical system.
Our germanium lenses Use a substantial refractive index—the highest refractive index amid available IR transmitters. What's more, it reveals minimal chromatic aberration as a result of low dispersion.
Rely on our talented crystal progress professionals to overcome these issues and provide demanding technical specs.
Fabrication: Our specially made handling and machining methods enable to get rid of sub-surface area hurt and chipping. We keep many best-high-quality multi-axis CNC vertical mills devoted to machining complex lenses in either production or prototype quantities.
To determine more about Germanium Home windows from UQG Optics, or any of our optical windows phone us on 01223 420329 or electronic mail our revenue group at [email protected]
Avantier Inc. is surely an unparalleled leader in supplying imaging devices alternatives and optical remedies.
In fact, at an eye fixed-popping Knoop Hardness of 2000kg/mm2, one could possibly speculate, why wouldn’t I just use sapphire windows instead of germanium? While sapphire could be the undisputed winner of strong optics inside the UV/VIS and mid-IR which has a wavelength variety that dips in the far UV vary at 150nm, it might only be employed approximately 4.

On the other hand, This is when they start diverging. Silicon is way lighter which has a density of two.33g/cm3, rendering it ideal for bodyweight-sensitive apps and a lot less than 50 % the density of germanium. Furthermore, it is much more thermally resistant than germanium and with a Knoop Hardness of 1150 Additionally it is more challenging and fewer brittle. Silicon also charges fewer rendering it a greater candidate in a number of website applications.
By increasing just one crystal, we make factors which has a consistent crystal composition and large purity.
The majority of the Uncooked content comes from China, Russia and USA being also vital suppliers, quality product is on the market just about everywhere.
Both equally germanium and germanium oxide are transparent to infrared radiation and so are generally Employed in the production of spherical lenses and windows for high performance infrared spectroscopes and thermal imaging devices.
An uncoated germanium window is a decent IR generalist but particular optical coatings can definitely kick points up a notch.
Uncooked germanium materials is rather challenging but can however effectively be machined and polished into optical parts:
