Depending on the application, we utilize highly resilient and economical antireflection coatings to your components. This tends to make them resistant and enhances transmission. We also check them in accordance with DIN ISO or MIL benchmarks.
Count on our talented crystal development professionals to beat these worries and deliver demanding specifications.
Germanium has outstanding thermal security. It might face up to superior operating temperatures without having degrading optical functionality.

Our metallic or dielectric coatings on mirrors are optimized to meet your necessities. At the same time, these coatings secure the components towards environmental influence and greatly enhance the reflection. Jenoptik assessments all parts in accordance with DIN ISO or MIL standards.
In truth, at an eye fixed-popping Knoop Hardness of 2000kg/mm2, just one could possibly speculate, why wouldn’t I just use sapphire windows as an alternative to germanium? Though sapphire will be the undisputed winner of sturdy optics while in the UV/VIS and mid-IR using a wavelength selection that dips in the significantly UV range at 150nm, it may only be utilized as much as four.
Grinding and polishing: The initial shaping on the germanium substrate making use of precision grinding and sprucing is vital to get a easy and uniform area. A number of techniques are adopted, Every read more with progressively finer abrasives, right up until we accomplish the specified floor complete.
Coatings: Specialized anti-reflective coatings and treatment plans can more increase the general performance of germanium optics by cutting down reflection and absorption, increasing transmission, and escalating longevity.
Firebird Optics manufactures these types of windows in various geometries, coatings and may also deliver lenses, prisms and many other optical elements from germanium. Now back again towards your regularly scheduled programming…
Ge lenses can transmit infrared wavelengths without having sizeable reduction, enabling for distinct and correct imaging.
Thanks to the compact design, you'll need fewer elements and components for diffractive optics than for typical programs. What is more, assembly is easier. This would make optical buildings for broadband apps far more Value-successful to put into practice.
Rather than needing numerous distinct cameras to accomplish every one of these responsibilities, you can save lots of money with “good” insert-on lenses which can be used amongst multiple compatible cameras with no Exclusive recalibration for each camera and manage to quickly swap out lenses on The task.
Uncooked germanium materials is quite tough but can nonetheless effectively be machined and polished into optical components:
