Germanium (Ge) Optics is applied in various Infrared (IR) systems. Its two most notable properties, which are its high index of refraction and its low optical dispersion make it very applicable for use in wide-angle camera lenses, microscopy, and in the optical fiber industry, which used up 60% of the annual germanium yield in 2002 Each aspheric lens is available uncoated, or with BBAR coating options. Uncoated germanium has transmission of <50%, so custom anti-reflection (AR) coatings should be considered if specifying an uncoated lens. Each BBAR coated lens offers >95% transmission, making it ideal for integration into a variety of OEM applications Germanium lenses (Ge lenses) is commonly used in IR imaging systems typically operating in the 2 µm to 16 µm spectral range, covers the LWIR (8-12μm) and MWIR (3-5μm) thermal imaging wavelength range. Germanium has the highest refractive index of commonly available IR-transmitters and has low optical dispersion. This makes it desirable in aspects of lens design where its refractive index. Germanium is mainly used in the thermal imaging system and infrared (FLIR) field. It is critical that the surface of the material has a promising finish and good transmittance. Hyperion Optics provides 40-20 surface quality Ge lenses as factory standard products, with up to 1/4 lambda in surface accuracy

Damage threshold specifications are constant for all Thorlabs' E3-coated, germanium lenses, regardless of the size or focal length of the lens. Laser Induced Damage Threshold Tutorial The following is a general overview of how laser induced damage thresholds are measured and how the values may be utilized in determining the appropriateness of an optic for a given application Germanium is also used extensively as a substrate for production of optical filters. Germanium covers the whole of the 8-14 micron thermal band and is used in lens systems for thermal imaging. Germanium can be AR coated with Diamond producing an extremely tough front optic

Germanium Lenses A

  1. This makes it desirable in aspects of lens design where its refractive index allows otherwise impossible specifications to be built. AR coating is recommended. Germanium transmits over 45% between 2-14μm up to 45⁰C but transmission degrades slowly at 100⁰C then more rapidly above 200⁰C
  2. eralen argydorit och germanit, men också ur stenkolsaska. Det kan separeras från andra metaller genom destillation av dess flyktiga tetraklorid, GeCl 4, som efter hydrolys till germaniumdioxid, GeO 2, och reduktion ger rent germanium
  3. Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbours silicon and tin.Pure germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature
