Ge can be intriguing for its minimal optical dispersion and thus extremely low chromatic dispersion in it’s transmission spectrum.
Our manufacturing personnel makes use of precision CNC curve turbines to generate most effective-in-class germanium lenses for any of your respective demands — from prototype requests by whole manufacturing volumes.
If superior transmission is the one thing to consider, you’d be best served to double coat your windows with BBAR around individual wavelength ranges and you can see transmissions every one of the way nearly ninety nine%. Now we’re conversing!

Careful handling and cleaning: Germanium optics are really difficult and brittle. Suitable cleansing and packaging strategies reduce any injury or contamination that would affect its optical efficiency.
It is the Specific hardness of germanium that offers it its exclusive ruggedness; Ge has a Knoop hardness of 780. This is a superior density materials, at five.33 g/cm3, and allowances needs to be created for this body weight If you're coming up with a weight sensitive program.
Grinding and sharpening: The Original shaping of the germanium substrate making use of precision grinding and sharpening is significant to get a easy and uniform surface area. A series of steps are followed, Each and every with ever more finer abrasives, right until we achieve the desired surface complete.
Specialized measurement and inspection: Utilizing specialised measurement resources and inspection equipment, we ensure that the surface roughness, curvature, and various important parameters satisfy demanding tolerances and good quality requirements.
Curiously, on account of its related crystal construction to Diamond may be coated with a DLC layer (Diamond Like Carbon) which in addition to cutting down the reflection on it’s surface area, adds a diamond potent protective layer. Ultimately Germanium is just not transparent in the obvious which may be helpful to concentrate on IR light-weight.
It's superior transmission while in the eight to 14 µm selection covering the thermal Infrared light-weight, consequently it can be a optical germanium lens material of choice for thermal and evening eyesight. Additionally, it demonstrates a high refractive index which permit superior open aperture angle optical element’s style and design.
Regular resistance for EMI-quality germanium is around 4 Ohm for each cm but this relies on the necessary volume of spurious sign suppression. A germanium window produced to these specs can proficiently short out any errant signals and preserve the IR process functioning nicely.
Manufacturing custom germanium lenses for prime-efficiency optical purposes calls for experience in germanium optics, Highly developed products like CNC curve turbines, and highly managed producing processes.
Uncooked germanium material is quite difficult but can continue to correctly be machined and polished into optical parts:
