Our spherical plano-concave germanium lenses are mostly utilized to diverge a beam from the collimated light supply, or to enhance the focal size of an optical program.
Germanium is likewise topic to thermal runaway. What This suggests is that the transmission will minimize as temperature boosts, as well as the lens becomes opaque. Due to this thermal runaway effect, germanium lenses really should only be utilized at temperatures down below 100°C.
Germanium has a lot of rewards, which makes it a suitable material for fabricating spherical lenses and aspheric lenses for various purposes in aerospace, protection, and infrared optics.

We provide precision cylinder lenses in round, rectangular or quadratic shapes to satisfy your necessities. The optical components can be found with substantial-reflection or antireflection coatings with the DUV, UV, VIS and IR spectral ranges. The Unique coating improves the cylinder lenses and can make them extra resistant. Information Sheet
It can be Minimize, polished and formed into lenses here and windows Utilized in infrared detector machines and also infrared spectroscopes.
Do you've got a tailor made necessity for germanium optical parts? Send us your distinct requirements, and our specialized gross sales representatives will examine what is necessary to provide ready-to-use elements within just your guide time.
Sprucing & coating: Our sprucing strategies supply exceptional levels of flatness, surface area roughness, and floor quality. Germanium lenses usually have to have optical or anti-reflection coatings to improve their functionality and toughness.
When you'll get an even better, extra managed cleaning and can be utilized for stubborn stains, care should be taken to work in a managed dampness-cost-free natural environment and we do not advise this for common finish-users.
Uncooked germanium content is quite tough but can nevertheless properly be machined and polished into optical elements:
