Our spherical plano-concave germanium lenses are mostly accustomed to diverge a beam from a collimated mild resource, or to raise the focal duration of an optical system.
However Germanium is sensible to large temperature with degradation of its optical Homes about a hundred°C.
Ahead your content requirements and We are going to answer having a estimate. For any other inquiries or inquiries be sure to Get hold of our educated income personnel.
Germanium retains the superior ground On the subject of transmission array finding that supplemental protection from seven-16µm, which silicon lacks. On top of this, germanium has increased electrical conductivity rendering it a far more suited applicant as an optical element in laser units.
We offer plane, spherical, aspherical, cylindrical and toric mirrors for a wide array of apps. They're made and made by Jenoptik to meet your unique needs. On top of that to conventional substrate resources, we also use metallic substrates.

Most often the coating applied is diamond-like carbon (DLC) that has a refractive index of 2.0. DLC is incredibly tough, which suggests that windows coated with it can be employed in ruggedised products which can be matter to severe environmental disorders.
Just like how visible light camera lenses certainly are a good glass condition, thermal digicam lenses are strong Germanium. Equally as glass is clear to noticeable gentle, Germanium is transparent towards the wavelength band of infrared radiation, which most thermal cameras use.
Infrared Filters, Windows and canopy Glass for Hermetic Solder Sealing We build and manufacture numerous optical filters. They may be used to improve the functionality of radiation detectors and influence the sign-to-noise ratio or reaction sensitivity of your detector. The coatings are appropriate for workpieces constructed from these components as germanium, silicon and sapphire.
Ge lenses can transmit infrared wavelengths without the need of sizeable loss, allowing for very clear and accurate imaging.
Mainly because these cookies are strictly necessary to produce the website, refusing them could have effect more info how our web site features.
Manufacturing tailor made germanium lenses for high-efficiency optical programs requires know-how in germanium optics, Highly developed products which include CNC curve generators, and really managed manufacturing procedures.
People are rookie quantities and for most programs we’ll will need to spice up our window alerts by means of various coatings. Even though This can be a downside for optical Home windows this property comes in handy for novel lens patterns and ATR optics where by refraction is sought after.
