Our germanium lenses Possess a higher refractive index—the best refractive index among available IR transmitters. In addition it reveals small chromatic aberration because of low dispersion.
We could manufacture aspheres in rotationally symmetrical, ellipsoid and off-axis designs to satisfy your particular needs. In this method, we're one of many couple corporations worldwide to work with several different optical supplies, like glass, glass ceramics, quartz glass, crystals like calcium fluoride, magnesium fluoride, germanium and silicon and metals. The antireflection coatings around the aspherical parts address a spectral vary from DUV to IR.

Shanghai Optics manufactures high quality germanium lenses in a range of well-known measurements, from 5m m to 350 mm in diameter.

Comparable to how visible light-weight digicam lenses can be a good glass shape, thermal digital camera lenses are good Germanium. Equally as glass is clear to visible gentle, Germanium is transparent to your wavelength band of infrared radiation, which most thermal cameras use.
Infrared Filters, Home windows and canopy Glass for Hermetic Solder Sealing We produce and manufacture many optical filters. They can be used to improve the effectiveness of radiation detectors and impact the signal-to-sound ratio or reaction sensitivity from the detector. The coatings are ideal for workpieces made from this kind of products as germanium, silicon and sapphire.
Do you do have a tailor made prerequisite for germanium optical parts? Ship us your distinct needs, and our technological revenue Associates will analyze what is required to deliver Prepared-to-use factors inside your guide time.
The sharp transmission Lower-off right before 2µm also enables germanium for use as a long go filter, only transmitting wavelengths in excess of 2µm and absolutely here blocking almost everything right before it.
When you'll get an even better, extra managed cleaning and can be utilized for stubborn stains, care needs to be taken to work in a controlled humidity-no cost setting and we don't propose this for usual conclude-users.
Up coming, the crystal is processed into the specified form working with precision chopping, grinding, and machining strategies to realize the exact flatness or curvature necessary.
