Plano-convex Ge lenses are flat on just one facet and convex on the opposite. These lenses Use a favourable focal duration, and will often be utilized for mild collimation.
Ge is likewise excellent electromagnetic interference (EMI) shielding material. Its Unique quality termed EMI for its power to defend in opposition to electromagnetic interference has grown to be progressively vital for modern armed service apps exactly where other alerts (inside millimeter and centimeter array) may be solid enough to create close by IR devices ineffective.
fiveµm. This leaves germanium as the best and only option for brutally difficult IR programs. This is often why you will see germanium Home windows and lenses serving in sites as inhospitable as outer Room, battlefields and in the midst of large-powered CO2 laser programs. Additional on this later.
Forward your material specifications and We're going to react with a estimate. For any other inquiries or issues make sure you Make contact with our proficient revenue personnel.
Jenoptik manufactures hybrid components in optical material for infrared purposes. They are perfect for infrared aim lenses and units, and also for picture seize, focus on detection and in infrared camera technological innovation. You'll be able to Pick from concave, convex, aircraft, spherical and aspherical surfaces. Info Sheet
Very careful handling and cleaning: Germanium optics are really tricky and brittle. Proper cleaning and packaging methods decrease any hurt or contamination that can have an impact on its optical performance.
It’s also a good choice when you’re scanning overhead vents or duct work, large-power transmission towers which might be a distance away. The telephoto lens allows you to work safely from the ground.
Germanium lenses are optical lenses made from polished germanium. Germanium Optics are rugged and immune to corrosion, and are ideal for severe environments and purposes wherever You can find continuous exposure to the elements.
We provide precision cylinder lenses in round, rectangular or quadratic designs to satisfy your prerequisites. The optical components can be found with significant-reflection or antireflection coatings for that DUV, UV, VIS and IR spectral ranges. The Exclusive coating boosts the cylinder lenses and makes them more resistant. Details Sheet
A large-angle lens expands your thermal digicam lens’ industry get more info of see. If you'd like to see a lot more of what’s bordering an asset, or are Doing work in a decent Room, they are mission significant to obtain the shot.
These superior-excellent cylinder optics are perfect for use in laser scanning, laser projection, beam homogenization and PCB fabrication. They're also a great solution in fault Assessment.
Polishing & coating: Our polishing methods deliver exceptional amounts of flatness, area roughness, and floor excellent. Germanium lenses generally call for optical or anti-reflection coatings to boost their effectiveness and toughness.
They may be Utilized in beam expanders, and can also be accustomed to equilibrium out aberrations which have been released by other lenses in an optical arrangement.
Raw germanium content is quite challenging but can however proficiently be machined and polished into optical factors:
