Our germanium lenses Have a very substantial refractive index—the very best refractive index among readily available IR transmitters. In addition, it exhibits small chromatic aberration on account of reduced dispersion.

Something about one hundredºC will not be advisable. By the point it reaches two hundredºC it is almost opaque whatsoever wavelengths. If you want a significant temperature window, you’re greater suited to follow a cloth like MgF2, YAG or our aged Pal sapphire.

Germanium has lots of strengths, which makes it a suitable materials for fabricating spherical lenses and aspheric lenses for many programs in aerospace, defense, and infrared optics.

Jenoptik manufactures hybrid parts in optical materials for infrared purposes. They are ideal for infrared aim lenses and programs, and for impression seize, focus on detection and in infrared camera technology. You are able to Decide on concave, convex, airplane, spherical and aspherical surfaces. Knowledge Sheet

Shanghai Optics manufactures top quality germanium lenses in A selection of common sizes, from 5m m to 350 mm in diameter.

Grinding and sharpening: The Original shaping of your germanium substrate making use of precision grinding and sprucing is important for the clean and uniform surface area. A number of steps are followed, each with ever more finer abrasives, until eventually we attain the desired area finish.

Even so, This is when they start diverging. Silicon is much lighter that has a density of 2.33g/cm3, rendering it ideal for excess weight-sensitive programs and below 50 percent the density of germanium. Moreover, it is more thermally resistant than germanium and by using a Knoop Hardness of 1150 It's also more challenging and fewer brittle. Silicon also costs fewer making it a much better applicant in numerous apps.

Curiously, because of its very similar crystal construction to Diamond could be coated with a DLC layer (Diamond Like Carbon) which along with lessening the reflection on it’s surface area, provides a diamond sturdy protective layer. Finally Germanium is just not clear in the seen that may be handy to concentrate on IR gentle.

Ge lenses can transmit infrared wavelengths devoid of important loss, making it possible for for very clear and exact imaging.

Germanium was first made use of on a substantial scale to exchange Among the most simple electronic parts, the diode.
