Lattice Materials is exceptionally equipped to produce optical factors, and germanium lenses particularly, to specific optical specifications with any finishing you demand.
Our germanium lenses Use a large refractive index—the very best refractive index among available IR transmitters. What's more, it exhibits minimum chromatic aberration resulting from low dispersion.
Everything more than one hundredºC is not advised. By the point it reaches two hundredºC it is nearly opaque in the least wavelengths. If you want a significant temperature window, you’re greater suited to stay with a fabric like MgF2, YAG or our old Mate sapphire.
Ahead your materials prerequisites and we will reply using a estimate. For any other inquiries or issues remember to contact our well-informed revenue workers.
Our totally built-in recycling business enterprise accepts your scrap germanium and gallium waste streams. This don't just relieves you on the obligation, but in addition creates an added profits stream wherever none may well previously have existed.
One more consideration is germanium’s density. At five.33g/cm3 it doesn't float like a butterfly and sting just like a bee. It’s major. Rather hefty and this may should be deemed when building excess weight-delicate units.
Both of those monocrystalline and polycrystalline Ge could possibly be employed for producing of optical parts. We develop Germanium lenses and Home windows for infrared thermal imaging programs and pyrometry (see our webpage Germanium Home windows and lenses for thermography).
When not in use, we propose storing your germanium windows wrapped in lens tissue with humidity beneath thirty% and among 15 and 25ºC. Though germanium is very hard things, they are The best problems which will prolong the everyday living of one's window.
We provide precision get more info cylinder lenses in spherical, rectangular or quadratic shapes to meet your demands. The optical factors can be found with significant-reflection or antireflection coatings for the DUV, UV, VIS and IR spectral ranges. The Particular coating boosts the cylinder lenses and will make them a lot more resistant. Info Sheet
These are extremely robust, safeguarded versus environmental influence and cost-powerful. The filters also fulfill all the necessities of the DIN ISO or MIL specifications and consist of no radioactive substances. If demanded, we can offer all filters with edges that are ideal for soldering, so that they are simple to integrate into your existing systems.
Germanium has a superior refractive index, so lenses crafted from Ge can concentration mild much more competently and supply larger-resolution imaging such as thermal cameras, distant sensing, and night eyesight gadgets.
This substantial-density window incorporates a thermal escape which makes the transmission cut down as being the temperature in the window increases.
They could be Utilized in beam expanders, and can even be utilized to equilibrium out aberrations which were released by other lenses within an optical arrangement.
Notice: As a result of recent improve while in the Chinese exporting policy, the exporting of Germanium optics is restrained and underneath stringent supervision. Please inquire us if you want to buy the Germanium Lenses
