Our germanium lenses have a significant refractive index—the best refractive index between available IR transmitters. In addition, it exhibits minimum chromatic aberration on account of low dispersion.
It is usually really worth noting that germanium is comparatively additional brittle that silicon and therefore needs to be cope with with treatment through machining.

Thickness of Germanium window demanded to withstand pressure differential at opposite sides may be calculated by the next equation:
1 cautionary detail to notice is that the germanium window is not going to recognize remaining exposed to large temperatures. The truth is, There may be an inverse romance to temperature and transmission In terms of this product. As your temperature goes up, the transmission Qualities will drop precipitously, a property often known as thermal runaway.
The truth is, at an eye fixed-popping Knoop Hardness of 2000kg/mm2, one particular may well speculate, why wouldn’t I just use sapphire Home windows in lieu of germanium? While sapphire is definitely the undisputed champion of sturdy optics while in the UV/VIS and mid-IR with a wavelength variety that dips in the significantly UV assortment at 150nm, it may only be employed up to four.
Novotech is a global supplier optical germanium lenses of evaporation grade Germanium. We assistance IR coating organizations along with the fiber optics marketplace with their product requires.

Aspherical germanium lenses : created and useful for Increased optical Qualities and for programs that need excess weight conserving. Germanium is usually diamond was higher floor high quality aspheres.
Below you could find listing of most important Attributes of Germanium in addition to its transmission and absorption spectra.
The sharp transmission cut-off just before twoµm also allows germanium for use as a lengthy pass filter, only transmitting wavelengths in excess of 2µm and completely blocking all the things before it.
Novotech Inc is able to take care of by far the most demanding IR and visible lens from prototype to high volume production. We employing the Most recent single point diamond turning and CNC sharpening devices accessible inside our facility...
