Our germanium lenses Possess a higher refractive index—the best refractive index among readily available IR transmitters. In addition it displays minimum chromatic aberration on account of reduced dispersion.
Depend upon our gifted crystal advancement experts to beat these issues and deliver demanding technical specs.
Germanium has quite a few rewards, which makes it an appropriate product for fabricating spherical lenses and aspheric lenses for various programs in aerospace, defense, and infrared optics.
To find out more details on Germanium Home windows from UQG Optics, or any of our optical Home windows simply call us on 01223 420329 or electronic mail our product sales group at facts@uqgoptics.com
Our metallic or dielectric coatings on mirrors are optimized to meet your demands. Concurrently, these coatings secure the elements in opposition to environmental impression and greatly enhance the reflection. Jenoptik assessments all factors in accordance with DIN ISO or MIL requirements.

On the other hand, this is where they begin diverging. Silicon is much lighter having a density of two.33g/cm3, rendering it perfect for excess weight-delicate apps and fewer than 50 % the density of germanium. What's more, it is more thermally resistant than germanium and which has a Knoop Hardness of 1150 It is additionally more challenging and less brittle. Silicon also fees fewer which makes it a far better applicant in a number of programs.
There are lots of technical problems in producing germanium elements for infrared optical techniques, for instance retaining superior optical excellent more than an array of temperatures, minimizing unwanted radial resistivity gradients, and lessening the absorption of infrared radiation.
Ge lenses can transmit infrared wavelengths without the need of major decline, letting for very clear and precise imaging.
The sharp transmission Lower-off just before 2µm also allows germanium to be used as a lengthy move filter, only transmitting wavelengths in surplus of twoµm and completely blocking all the things ahead of it.
Manufacturing customized germanium lenses for prime-functionality optical apps necessitates knowledge in germanium optics, State-of-the-art tools like CNC curve generators, and hugely managed production procedures.
