Our spherical plano-concave germanium lenses are largely utilized to diverge a beam from a collimated gentle resource, or to improve the focal size of an optical process.
Everything in excess of 100ºC is just not encouraged. By the time it reaches 200ºC it is almost opaque at all wavelengths. If you want a significant temperature window, you’re improved suited to stay with a material like MgF2, YAG or our outdated Close friend sapphire.
Fabrication: Our specially designed dealing with and machining approaches assistance to remove sub-floor problems and chipping. We sustain various major-excellent multi-axis CNC vertical mills dedicated to machining complex lenses in either generation or prototype portions.

They may also be used in concentrating applications, and also have prevalent use in a variety of fields, from science to market to protection. We advocate these lenses be oriented so that the flat facet faces the desired focal aircraft.
Our in dwelling creation abilities allow for us to provide brief guide-situations and quality product at aggressive charges. We manufacture both typical evaporation measurements and personalized measurements on ask for...
Germanium’s optical germanium lens transparency in the infrared wavelengths enable it to be an important and widely utilised substance in infrared optics.
Routinely, DLC coatings tend to be paired with Broadband AR Coatings (BBAR) to don't just up the mechanical performance but in addition the transmission Homes. Generally, a window is coated on 1 side with DLC and the opposite aspect with BBAR (generally while in the 7-14μm range to boost the two of these Qualities in tandem.
Firebird Optics manufactures these sorts of Home windows in different geometries, coatings and may also create lenses, prisms and many other optical factors from germanium. Now back to your frequently scheduled programming…
We could make personalized specs to non-common sizes of optical crystals. Novotech can provide the material fabricated to most customer’s specs. With an intensive fabrication capacity, we can easily deliver common generated lens blanks inside a one particular-to 2-week time frame.
Sprucing & coating: Our sharpening tactics produce Excellent amounts of flatness, surface area roughness, and area excellent. Germanium lenses generally require optical or anti-reflection coatings to further improve their effectiveness and toughness.
Knowing the distinction between the various lens kinds may also help determine which one to employ when so as to get most troubleshooting data.
Germanium (Ge) is really a shiny, really hard element with a Knoop Hardness of 780kg/mm2 rendering it, together with its far stronger sister sapphire, the default prospect for purposes the place the natural environment is likely To place a beating on the fabric.
