Plano-convex Ge lenses are flat on just one side and convex on another. These lenses Use a constructive focal size, and are often utilized for mild collimation.
Our germanium lenses Possess a large refractive index—the highest refractive index amid readily available IR transmitters. Furthermore, it reveals small chromatic aberration as a result of low dispersion.
Trust in our talented crystal development experts to overcome these difficulties and provide demanding technical specs.
Novotech has the ability to complete diamond turning, sharpening, and custom made producing for all orders from prototype to creation quantities.
You definitely don’t need to breathe in germanium dust so care have to be taken even though handling these optics. Employing gloves Every time possible and washing palms should be part of any common running technique.

Shanghai Optics manufactures high quality germanium lenses in a range of well-known dimensions, from 5m m to 350 mm in diameter.
When not in use, we advise storing your germanium Home windows wrapped in lens tissue with humidity down below thirty% and among fifteen and twenty fiveºC. Though germanium is very tough things, these are generally the ideal situations which will extend the lifetime of your respective window.
Specialised measurement and inspection: Working with specialized measurement applications and inspection products, we be sure that the surface area roughness, curvature, along with other vital parameters meet strict tolerances and high-quality expectations.
They are exceptionally sturdy, secured against environmental effects and cost-productive. The filters also meet all the requirements from the DIN ISO or MIL expectations and have no radioactive substances. If needed, we can provide all filters with edges which have been well suited for soldering, so that they're simple to combine into your current methods.
Germanium is just not mined being a Main metallic but is developed like a by-product of zinc production and also from optical germanium lens coal fly ash.
Coatings from Jenoptik enable you to guideline beams in a specific method. They filter particular wavelengths, reflect optics or redirect them and lessen reflection if demanded. We offer the following:
