Our germanium lenses Have a very significant refractive index—the highest refractive index among readily available IR transmitters. In addition, it exhibits minimum chromatic aberration because of small dispersion.
fiveµm. This leaves germanium as the ideal and only choice for brutally hard IR programs. This is often why you will note germanium windows and lenses serving in locations as inhospitable as outer Room, battlefields and in the course of superior-run CO2 laser devices. More on this later on.
Fabrication: Our specifically produced handling and machining approaches aid to eradicate sub-surface problems and chipping. We preserve many top-excellent multi-axis CNC vertical mills devoted to machining elaborate lenses in both production or prototype portions.
No water solubility- benefit about salty Home windows like KBr and NaCl which might be exceptionally hygroscopic.
Our metallic or dielectric coatings on mirrors are optimized to satisfy your needs. Simultaneously, these coatings shield the factors against environmental impression and boost the reflection. Jenoptik tests all factors in accordance with DIN ISO or MIL expectations.
Germanium can be applied extensively as a substrate for production of optical filters. Germanium addresses The full from the 8-fourteen micron thermal band and is particularly Utilized in lens techniques for thermal imaging. Germanium might be AR coated with Diamond developing a particularly difficult entrance optic.
When not in use, we propose storing your germanium windows wrapped in lens tissue with humidity beneath thirty% and between fifteen and twenty fiveºC. Whilst germanium is rather rough things, they are The perfect problems that may lengthen the lifestyle of one's window.
Thermal digital camera lenses are created of Germanium because of the content’s unique Houses with respect on the Infrared spectrum. Germanium is a component you could find during the periodic table and directly from mother nature.
Firebird Optics manufactures these kind of windows in various geometries, coatings and may also produce lenses, prisms and a variety of other optical factors from germanium. Now back to the routinely scheduled programming…
Do you have a customized necessity for germanium optical components? Send us your particular specifications, and our specialized product sales representatives will evaluate what is needed to provide Completely ready-to-use factors within just your direct time.

All those are rookie quantities and for most applications we’ll require to boost our window signals by click here way of different coatings. Even though This can be a drawback for optical windows this house comes in useful for novel lens patterns and ATR optics in which refraction is sought after.
