Our germanium lenses Have got a high refractive index—the highest refractive index amid available IR transmitters. It also reveals negligible chromatic aberration resulting from small dispersion.

Germanium has fantastic thermal stability. It could possibly face up to high working temperatures without the need of degrading optical efficiency.

A different thought is germanium’s density. At five.33g/cm3 it does not float like a butterfly and sting similar to a bee. It’s heavy. Fairly major and this tends to have to be viewed as when planning weight-delicate devices.

Shanghai Optics manufactures high quality germanium lenses in A variety of well-known sizes, from 5m m to 350 mm in diameter.

Novotech is a global provider of evaporation grade Germanium. We assistance IR coating companies and the fiber optics marketplace with their product wants.

When this product is shielded by a thoroughly engineered anti-reflective coating, it results in being an amazingly successful product to transmit energy to your thermal camera detector and generate higher-top quality thermal pictures. The coating can be intended with ruggedness in mind which improves scratch resistance.

Apparently, on account of its similar crystal framework to Diamond might be coated using a DLC layer (Diamond Like Carbon) which along with minimizing the reflection on it’s floor, adds a diamond solid protective layer. Last but not least Germanium is not really transparent from the visible which may be handy to give attention to IR light.

At Shanghai Optics we manufacture here a wide variety of germanium lenses with different anti reflection coatings. Spherical plano-concave, p-convex, concave-convex and aspheric lenses are all offered in lots of dimensions. We will also be equipped to support Particular orders in the event you need a dimensions, shape or AR coating.

At Lattice Resources, we custom made manufacture germanium lenses by using a perfectly-described and managed procedure to make sure that they meet up with stringent performance necessities:

Optical precision is vital to meet distinct demands related to accuracy, surface area high-quality, and Total optical efficiency.
