Plano-convex Ge lenses are flat on just one side and convex on another. These lenses have a beneficial focal length, and tend to be employed for light-weight collimation.
Dependant upon the application, we implement very resilient and productive antireflection coatings into the components. This tends to make them resistant and improves transmission. We also take a look at them in accordance with DIN ISO or MIL criteria.
It's also really worth noting that germanium is comparatively a lot more brittle that silicon and as a consequence ought to be deal with with care through machining.
Novotech Inc has comprehensive CNC making abilities. We are an industry leader giving the marketplace with produced and pre-produced optical blanks.
Jenoptik manufactures hybrid parts in optical material for infrared apps. They are perfect for infrared objective lenses and programs, and for impression seize, focus on detection As well as in infrared camera technological know-how. You could choose from concave, convex, aircraft, spherical and aspherical surfaces. Information Sheet

The quantity of holes existing can be lessened by escalating the quantity of electrons via the addition of group V atoms (donors) for the Ge. This lowers resistivity. Excessive addition of donors contributes to excessive electron focus and increased absorption.
Thermal digital camera lenses are made of Germanium due to material’s unique properties with respect for the Infrared spectrum. Germanium is an element you will find while in the periodic table and directly from nature.
Firebird Optics manufactures these types of Home windows in different geometries, coatings and might also deliver lenses, prisms and numerous other optical elements from germanium. Now back again to the consistently scheduled programming…
It's got fantastic transmission from the 8 to 14 µm vary covering the thermal Infrared light, hence it can be a material of option for thermal and evening eyesight. What's more, it exhibits a high refractive index which empower substantial open up aperture angle optical part’s design and style.
The sharp transmission Slash-off in advance of twoµm also allows germanium for use as a lengthy move filter, only transmitting wavelengths in excessive of 2µm and entirely blocking almost everything prior to it.
At Lattice Components, we custom manufacture germanium lenses having a nicely-defined check here and controlled course of action to make certain that they satisfy stringent effectiveness demands:
Notice: Mainly because of the recent change while in the Chinese exporting coverage, the exporting of Germanium optics is restrained and underneath stringent supervision. Please inquire us if you want to order the Germanium Lenses
