Our spherical plano-concave germanium lenses are primarily used to diverge a beam from a collimated mild supply, or to increase the focal size of the optical program.
It is also worth noting that germanium is comparatively additional brittle that silicon and therefore needs to be take care of with care in the course of machining.
Fabrication: Our specifically created managing and machining strategies aid to get rid of sub-floor damage and chipping. We maintain numerous prime-high-quality multi-axis CNC vertical mills devoted to machining advanced lenses in possibly manufacturing or prototype quantities.

Avantier Inc. is an unparalleled leader in offering imaging units options and optical remedies.
Avantier Inc. is surely an unparalleled chief in offering imaging systems alternatives and optical options.
Germanium lenses are optical lenses made from polished germanium. Germanium Optics are rugged and immune to corrosion, and are ideal for severe environments and applications wherever There is certainly regular exposure to The weather.
We provide precision cylinder lenses in spherical, rectangular or quadratic designs to meet your necessities. The optical factors are available with high-reflection or antireflection coatings for that DUV, UV, VIS and IR spectral ranges. The Specific coating enhances the cylinder lenses and helps make them much more resistant. Data Sheet
One particular quite common circumstance we see germanium utilized is within large and very low speed wind tunnels for jet propulsion scientific studies. Normally, these windows are much larger than stock configurations achieving dimensions in excessive of a hundred ninety-200mm.
Germanium is actually a significant index material that is certainly used to manufacture Attenuated Total Reflection (ATR) prisms for spectroscopy. Its refractive index is these types of that Germanium helps make a powerful organic fifty% beamsplitter without the require for coatings.
The sharp transmission Lower-off prior to 2µm also enables germanium for use as a long go filter, only transmitting wavelengths in extra of twoµm and completely blocking every thing right before it.
Realizing the distinction between different lens types might help select which just one to implement when so as to get most troubleshooting facts.
