Earlier mentioned value are generic technical specs for fabrication, precise much better price may be available and have to be reviewed scenario by scenario.
Unfortunately Germanium is reasonable to higher temperature with degradation of its optical Attributes above 100°C.
Deliver us your particular necessities, and our technological income Associates will examine what is required to provide Completely ready-to-use factors in just your direct time.
To discover more details on Germanium Home windows from UQG Optics, or any of our optical windows call us on 01223 420329 or electronic mail our gross sales team at [email protected]
Wafers : for a semi conductor materials, like Silicon, it truly is commonly utilized as a thin substrate for Digital element.
In fact, at an eye-popping Knoop Hardness of 2000kg/mm2, one read more may possibly marvel, why wouldn’t I just use sapphire Home windows rather than germanium? Even though sapphire could be the undisputed winner of robust optics while in the UV/VIS and mid-IR which has a wavelength selection that dips into the significantly UV range at 150nm, it could possibly only be used as much as 4.
Grinding and sharpening: The First shaping of the germanium substrate utilizing precision grinding and sprucing is crucial for your easy and uniform floor. A series of measures are adopted, each with ever more finer abrasives, until eventually we obtain the desired floor end.
This helps make Ge ideal for use in programs in which lenses are subjected to Severe environmental conditions or demand productive heat dissipation, such as infrared cameras used in aerospace or armed service applications.
By expanding an individual crystal, we generate components having a steady crystal composition and large purity.
Germanium is not mined for a Major metallic but is produced as a by-product or service of zinc manufacturing and from coal fly ash.

Content Collection: Large-top quality germanium substrate is essential for producing substantial-efficiency lenses, as any defects or impurities in the germanium crystals could affect the optical Attributes of your concluded lens. Depend upon Lattice to provide high-quality custom made-grown germanium to be sure high-excellent lenses.
Uncooked germanium materials is very tricky but can however proficiently be machined and polished into optical components:
