Lattice Components is extremely Outfitted to develop optical elements, and germanium lenses especially, to specific optical requirements with any finishing you demand.
Our germanium lenses have a large refractive index—the best refractive index amongst readily available IR transmitters. It also exhibits minimum chromatic aberration as a consequence of lower dispersion.
Depend on our gifted crystal development professionals to beat these problems and provide demanding technical specs.

They can be Utilized in concentrating programs, and possess popular use in a variety of fields, from science to sector to defense. We endorse these lenses be oriented so the flat aspect faces the specified focal aircraft.
It is the Exclusive hardness of germanium that offers it its distinctive ruggedness; Ge includes a Knoop hardness of 780. It is a superior density product, at 5.33 g/cm3, and allowances must be website built for this body weight Should you be designing a body weight sensitive technique.

Having said that, This is when they begin diverging. Silicon is far lighter by using a density of two.33g/cm3, which makes it perfect for weight-sensitive purposes and less than fifty percent the density of germanium. Furthermore, it is much more thermally resistant than germanium and by using a Knoop Hardness of 1150 It's also more durable and fewer brittle. Silicon also prices fewer making it a better applicant in numerous programs.
Infrared Filters, Home windows and Cover Glass for Hermetic Solder Sealing We build and manufacture numerous optical filters. They are often utilized to Increase the functionality of radiation detectors and affect the sign-to-noise ratio or reaction sensitivity with the detector. The coatings are suited to workpieces made out of this sort of components as germanium, silicon and sapphire.
Beneath you could find list of main Houses of Germanium together with its transmission and absorption spectra.
Sharpening & coating: Our polishing techniques deliver exceptional amounts of flatness, floor roughness, and surface area top quality. Germanium lenses frequently need optical or anti-reflection coatings to improve their performance and longevity.
Manufacturing customized germanium lenses for prime-functionality optical applications requires knowledge in germanium optics, Sophisticated tools such as CNC curve turbines, and remarkably managed production processes.
Uncooked germanium have a comparatively ordinary transmission in the IR (less than fifty%) but Anti-replicate or DLC solutions do strengthen quite a bit it’s transmittance.
