Our germanium lenses Have got a large refractive index—the best refractive index among the available IR transmitters. What's more, it reveals minimal chromatic aberration as a consequence of lower dispersion.
Germanium can be matter to thermal runaway. What this means is that the transmission will lessen as temperature increases, along with the lens becomes opaque. For this reason thermal runaway result, germanium lenses should only be employed at temperatures underneath 100°C.
Germanium has fantastic thermal security. It could endure substantial operating temperatures without the need of degrading optical general performance.
You unquestionably don’t choose to breathe in germanium dust so treatment has to be taken although handling these optics. Applying gloves When attainable and washing fingers should be Element of any typical working procedure.
Be sure to be aware this could possibly heavily reduce the operation and look of our web site. Adjustments will consider effect as you reload the site.
Our in home output capabilities allow us to supply brief lead-situations and excellent product at aggressive charges. We manufacture the two typical evaporation dimensions and custom sizes on request...

Just like how noticeable light camera lenses really are a reliable glass shape, thermal camera lenses are sound Germanium. Just as glass is transparent to noticeable light, Germanium is clear to your wavelength band of infrared radiation, which most thermal cameras use.
They may be particularly strong, protected against environmental influence and value-successful. The filters also satisfy all the necessities of your DIN ISO or MIL requirements and incorporate no radioactive substances. If essential, we can offer all filters with edges that happen to be suited to soldering, so that they're simple to integrate into your present systems.
The vast majority of Uncooked material originates from China, Russia and United states currently being also significant suppliers, high-quality material is accessible almost everywhere.
This significant-density window incorporates a thermal escape that makes the transmission lessen because the temperature of your window will increase.
Material Assortment: High-good quality germanium substrate is crucial for making substantial-performance lenses, as any defects or impurities inside the germanium crystals could effects the optical properties in the completed lens. Rely upon Lattice to provide higher-grade custom made-grown germanium to be sure significant-quality lenses.
Optical windows : major utilization of germanium with very good transmission within the IR and no transmission within the visible. Often, here germanium Home windows are strengthened with DLC coating on just one experience.
