Our germanium lenses Possess a substantial refractive index—the best refractive index among readily available IR transmitters. Furthermore, it displays minimal chromatic aberration on account of small dispersion.
Everything about one hundredºC is not really recommended. By the time it reaches 200ºC it is sort of opaque in the slightest degree wavelengths. If you want a higher temperature window, you’re better suited to stay with a cloth like MgF2, YAG or our previous friend sapphire.
If high transmission is the sole consideration, you’d be ideal served to double coat your windows with BBAR about distinct wavelength ranges and you will see transmissions every one of the way around ninety nine%. Now we’re talking!

Wafers : for a semi conductor material, like Silicon, it can be greatly utilized as read more a thin substrate for electronic element.

Specialised measurement and inspection: Working with specialized measurement resources and inspection devices, we ensure that the floor roughness, curvature, as well as other important parameters meet strict tolerances and quality standards.
By escalating only one crystal, we make components that has a steady crystal composition and large purity.
Germanium provides a higher refractive index, so lenses crafted from Ge can focus mild additional competently and deliver larger-resolution imaging for instance thermal cameras, distant sensing, and night time eyesight equipment.
Coatings from Jenoptik enable you to manual beams inside of a focused fashion. They filter certain wavelengths, mirror optics or redirect them and reduce reflection if expected. We provide the following:
They may be used in beam expanders, and can also be used to harmony out aberrations which were being launched by other lenses within an optical arrangement.
Raw germanium have a relatively common transmission inside the IR (below 50%) but Anti-reflect or DLC remedies do boost a whole lot it’s transmittance.
