Our germanium lenses have a higher refractive index—the best refractive index among available IR transmitters. Additionally, it displays minimal chromatic aberration resulting from reduced dispersion.
We are able to manufacture aspheres in rotationally symmetrical, ellipsoid and off-axis shapes to satisfy your precise specifications. In this method, we are one of the few organizations around the world to make use of various optical elements, for example glass, glass ceramics, quartz glass, crystals which include calcium fluoride, magnesium fluoride, germanium and silicon and metals. The antireflection coatings around the aspherical elements go over a spectral range between DUV to IR.

Thorough managing and cleaning: Germanium optics are very challenging and brittle. Right cleaning and packaging processes lessen any harm or contamination that may have an impact on its optical performance.
Both of those monocrystalline and polycrystalline Ge could possibly be utilized for production of optical factors. We produce Germanium lenses and Home windows for infrared thermal imaging applications and pyrometry (see our webpage Germanium Home windows and lenses for thermography).

This helps make Ge ideal for use in purposes wherever lenses are subjected to Excessive environmental problems or demand efficient warmth dissipation, like infrared cameras Employed in aerospace or armed service programs.
Aspherical germanium lenses : developed and employed for Increased optical Attributes and for programs that need bodyweight conserving. Germanium is often diamond turned into large floor quality aspheres.
Germanium is actually a substantial index materials that's used to manufacture Attenuated Complete Reflection (ATR) prisms for spectroscopy. Its refractive index is these that Germanium would make a powerful normal fifty% beamsplitter with no need to have for coatings.
