Our germanium lenses have a large refractive index—the very best refractive index amongst available IR transmitters. Furthermore, it exhibits nominal chromatic aberration as a result of low dispersion.
We will manufacture aspheres in rotationally symmetrical, ellipsoid and off-axis styles to fulfill your specific specifications. In this method, we've been one of many couple organizations worldwide to work with many different optical elements, like glass, glass ceramics, quartz glass, crystals for example calcium fluoride, magnesium fluoride, germanium and silicon and metals. The antireflection coatings over the aspherical components include a spectral vary from DUV to IR.
Welcome to UQG Optics! It appears like that you are going to from outdoors the united kingdom. Find your most well-liked currency beneath to determine suitable pricing. Contact us For added assist or to discuss unique prerequisites.
No drinking water solubility- edge about salty windows including KBr and NaCl which might be really hygroscopic.
We offer plane, spherical, aspherical, cylindrical and toric mirrors for a wide range of programs. They're developed and produced by Jenoptik to meet your distinct necessities. Moreover to conventional substrate check here materials, we also use metallic substrates.
It’s also a good choice in case you’re scanning overhead vents or duct do the job, substantial-power transmission towers that happen to be a length away. The telephoto lens means that you can work securely from the ground.
When not in use, we advocate storing your germanium Home windows wrapped in lens tissue with humidity underneath 30% and involving 15 and 25ºC. Though germanium is quite tough stuff, these are The perfect disorders that may lengthen the lifestyle of the window.

1 quite common situation we see germanium used is inside significant and reduced pace wind tunnels for jet propulsion studies. Typically, these windows are much bigger than stock configurations achieving sizes in surplus of one hundred ninety-200mm.
Do you have a customized prerequisite for germanium optical factors? Send us your certain necessities, and our technical revenue representatives will evaluate what is needed to provide ready-to-use components inside your lead time.
Coatings from Jenoptik let you guideline beams inside a focused method. They filter certain wavelengths, reflect optics or redirect them and minimize reflection if necessary. We offer the following:
They may be used in beam expanders, and will also be used to stability out aberrations which were being launched by other lenses within an optical arrangement.
Germanium was initially utilised on a sizable scale to interchange Among the most fundamental Digital components, the diode.
