Our germanium lenses Have got a higher refractive index—the highest refractive index amid available IR transmitters. In addition, it reveals nominal chromatic aberration as a consequence of lower dispersion.
Depend upon our proficient crystal progress professionals to beat these problems and deliver demanding technical specs.
If large transmission is the only real thought, you’d be very best served to double coat your Home windows with BBAR in excess of particular wavelength ranges and you'll see transmissions many of the way as much as ninety nine%. Now we’re conversing!
Jenoptik manufactures hybrid factors in optical product for infrared apps. They are ideal for infrared aim lenses and devices, along with for picture seize, focus on detection As well as in infrared camera engineering. You'll be able to choose from concave, convex, aircraft, spherical and aspherical surfaces. Knowledge Sheet

Shanghai Optics manufactures high quality germanium lenses in a range of well known measurements, from 5m m read more to 350 mm in diameter.
Click on different group headings to determine more. You can even change some of your Choices. Take note that blocking some different types of cookies may well influence your knowledge on our Internet websites plus the expert services we can give.
Specialized measurement and inspection: Working with specialized measurement equipment and inspection machines, we make sure that the surface area roughness, curvature, together with other significant parameters meet strict tolerances and high quality requirements.
They're extremely strong, shielded towards environmental effect and cost-efficient. The filters also fulfill all the necessities in the DIN ISO or MIL specifications and contain no radioactive substances. If demanded, we can offer all filters with edges which can be ideal for soldering, so that they're simple to combine into your existing units.
Ge lenses can transmit infrared wavelengths with out considerable loss, enabling for obvious and correct imaging.
The sharp transmission Reduce-off prior to twoµm also enables germanium for use as an extended pass filter, only transmitting wavelengths in surplus of 2µm and absolutely blocking anything just before it.
Product Assortment: Large-top quality germanium substrate is very important for creating higher-performance lenses, as any defects or impurities in the germanium crystals could effects the optical Houses on the concluded lens. Trust in Lattice to supply superior-grade custom-developed germanium to ensure higher-high-quality lenses.
Raw germanium have a relatively regular transmission within the IR (fewer than 50%) but Anti-replicate or DLC treatment options do make improvements to a good deal it’s transmittance.
