Lattice Products is extremely equipped to generate optical components, and germanium lenses in particular, to specific optical technical specs with any ending you have to have.
Germanium helps make a fantastic electromagnetic interference (EMI) shielding material and will shield IR techniques on planes from other close by indicators that will render the program ineffective. This properly results in an IR Faraday cage or as we want to check with it, an aerospace tin foil hat.
fiveµm. This leaves germanium as the very best and only option for brutally hard IR apps. This is typically why you will notice germanium windows and lenses serving in locations as inhospitable as outer Place, battlefields and in the midst of superior-driven CO2 laser units. Additional on this later on.

It is the Distinctive hardness of germanium that provides it its unique ruggedness; Ge features a Knoop hardness of 780. This is a superior density content, at five.33 g/cm3, and allowances has to be manufactured for this weight When you are creating a bodyweight sensitive method.
The end intention is to create germanium optics that meet or exceed the demanding demands of assorted purposes, from infrared thermal imaging and sensing to spectroscopy and laser methods.
We provide precision cylinder lenses in round, rectangular or quadratic styles to fulfill your specifications. The optical elements can be found with substantial-reflection or antireflection coatings for that DUV, UV, VIS and IR spectral ranges. The Distinctive coating boosts the cylinder lenses and makes them more resistant. Information Sheet
Apparently, because of its identical crystal framework to Diamond may be coated with a DLC layer (Diamond Like Carbon) which in addition to lowering the reflection on it’s floor, adds a diamond get more info potent protective layer. Lastly Germanium is not clear within the seen that may be beneficial to deal with IR light.
Germanium is usually a higher index content that is definitely used to manufacture Attenuated Complete Reflection (ATR) prisms for spectroscopy. Its refractive index is these kinds of that Germanium will make an effective organic fifty% beamsplitter with no have to have for coatings.

As an alternative to needing multiple diverse cameras to accomplish every one of these tasks, you can save lots of money with “smart” incorporate-on lenses which might be utilized amid various compatible cameras with no Specific recalibration for every digicam and manage to quickly swap out lenses on the job.
Notice: Due to the latest improve within the Chinese exporting coverage, the exporting of Germanium optics is restrained and less than stringent supervision. Remember to inquire us if you want to order the Germanium Lenses
