Our spherical plano-concave germanium lenses are mostly used to diverge a beam from the collimated light source, or to increase the focal size of the optical program.
We can easily manufacture aspheres in rotationally symmetrical, ellipsoid and off-axis designs to fulfill your particular requirements. In this process, we're one of many couple of firms around the globe to implement many different optical materials, like glass, glass ceramics, quartz glass, crystals which include calcium fluoride, magnesium fluoride, germanium and silicon and metals. The antireflection coatings within the aspherical parts cover a spectral range from DUV to IR.
Ship us your unique demands, and our technical profits representatives will assess what is necessary to deliver Completely ready-to-use elements within your direct time.
In the event you’re scanning a big spot that’s even further absent, such as the ceiling or roof of a manufacturing unit or warehouse, you’ll need a telephoto lens (2x or 4x is usually gives sufficient zoom) to be able to begin to see the detail you will need from more absent.
Avantier Inc. can be an unparalleled leader in delivering imaging methods methods and optical answers.
Each monocrystalline and polycrystalline Ge can be used for production of optical parts. We produce Germanium lenses and windows for infrared thermal imaging apps and pyrometry (see our webpage Germanium Home windows and lenses for thermography).
Most often the coating applied is diamond-like carbon (DLC) that has a refractive index of two.0. DLC is extremely tough, which means that windows coated with it may be used in ruggedised products which may be matter to harsh environmental ailments.

They can be very strong, shielded versus environmental affect and value-efficient. The filters also meet up with all the necessities from the DIN ISO or MIL benchmarks and have no radioactive substances. If expected, we can offer all filters with edges which can be suited to soldering, so that they're easy to integrate into your present units.
Germanium is often a significant index content which is utilized to manufacture Attenuated Overall Reflection (ATR) prisms for spectroscopy. Its refractive index is this kind of that Germanium will make a highly click here effective purely natural fifty% beamsplitter with no want for coatings.

Materials Selection: Substantial-high-quality germanium substrate is vital for producing high-overall performance lenses, as any defects or impurities during the germanium crystals could influence the optical Qualities on the completed lens. Depend upon Lattice to offer significant-quality personalized-developed germanium to guarantee significant-high-quality lenses.
Germanium (Ge) can be a shiny, really hard factor using a Knoop Hardness of 780kg/mm2 making it, along with its considerably more powerful sister sapphire, the default candidate for apps in which the atmosphere is probably going to put a beating on the fabric.
