It is usually truly worth noting that germanium is pretty much more brittle that silicon and therefore need to be tackle with care for the duration of machining.
Germanium has numerous benefits, making it an acceptable product for fabricating spherical lenses and aspheric lenses for many apps in aerospace, defense, and infrared optics.

An additional consideration is germanium’s density. At 5.33g/cm3 it doesn't float just like a butterfly and sting just like a bee. It’s weighty. Rather significant and this could must be regarded when planning fat-sensitive systems.

Germanium lenses are optical lenses product of polished germanium. Germanium Optics are rugged and immune to corrosion, and are perfect for severe environments and programs exactly where There is certainly continual publicity to The weather.
However, This is when they begin diverging. Silicon is much lighter which has a density of 2.33g/cm3, rendering it ideal for excess weight-delicate applications and fewer than fifty percent the density of germanium. Furthermore, it is a lot more thermally resistant than germanium and having a Knoop Hardness of 1150 It's also more durable and less brittle. Silicon also charges considerably less rendering it a much better candidate in quite a few applications.
A large-angle lens expands your thermal camera lens’ industry of check out. In order to see much more of what’s bordering an asset, or are Performing in a tight House, They can be mission crucial to find the shot.
At Shanghai Optics we manufacture lots of germanium lenses with various anti reflection coatings. Spherical plano-concave, p-convex, concave-convex and aspheric lenses are all offered in numerous types of dimensions. We can also be ready to support special orders must you require a dimensions, condition or AR coating.
Making a one crystal of germanium is definitely the start line for manufacturing significant-good quality components. The crystal composition and defect more info density can drastically have an effect on its optical and electrical properties.
Product Collection: Significant-excellent germanium substrate is critical for generating higher-performance lenses, as any defects or impurities during the germanium crystals could affect the optical Qualities of the completed lens. Rely on Lattice to offer higher-quality custom-developed germanium to make sure significant-excellent lenses.
Uncooked germanium materials is rather tricky but can continue to correctly be machined and polished into optical factors:
