Our germanium lenses Have a very superior refractive index—the best refractive index between available IR transmitters. In addition it exhibits small chromatic aberration as a consequence of very low dispersion.
We can easily manufacture aspheres in rotationally symmetrical, ellipsoid and off-axis shapes to fulfill your unique demands. In this method, we have been on the list of couple corporations worldwide to use a range of optical products, like glass, glass ceramics, quartz glass, crystals for example calcium fluoride, magnesium fluoride, germanium and silicon and metals. The antireflection coatings on the aspherical factors protect a spectral range from DUV to IR.
Be sure to be aware this may possibly heavily reduce the features and visual appeal of our web page. Changes will acquire impact as soon as you reload the web page.
Jenoptik manufactures hybrid parts in optical substance for infrared programs. They are ideal for infrared goal lenses and systems, along with for impression seize, concentrate on detection and in infrared digital camera technological know-how. You can choose from concave, convex, airplane, spherical and aspherical surfaces. Facts Sheet
Our metallic or dielectric coatings on mirrors are optimized to fulfill your specifications. Simultaneously, these coatings protect the read more factors towards environmental affect and boost the reflection. Jenoptik checks all factors in accordance with DIN ISO or MIL specifications.
In actual fact, at an eye-popping Knoop Hardness of 2000kg/mm2, one particular might speculate, why wouldn’t I just use sapphire Home windows rather than germanium? Although sapphire may be the undisputed champion of sturdy optics during the UV/VIS and mid-IR by using a wavelength array that dips in the far UV assortment at 150nm, it may only be utilized around four.

Coatings: Specialized anti-reflective coatings and treatment plans can even more improve the functionality of germanium optics by lowering reflection and absorption, bettering transmission, and increasing durability.
There are several technical difficulties in producing germanium factors for infrared optical systems, such as retaining substantial optical good quality in excess of an array of temperatures, reducing undesirable radial resistivity gradients, and reducing the absorption of infrared radiation.
Down below you will discover listing of primary Qualities of Germanium as well as its transmission and absorption spectra.
Jenoptik´s OrthoLine optical alignment cubes are made mostly for processes that have to have precision datum registration - which include purposes while in the lifestyle and health sciences, metrology and protection.
They could be Utilized in beam expanders, and may also be accustomed to harmony out aberrations which have been released by other lenses in an optical arrangement.
