Lens ya Germany (Ge lens) ya Infrared Applications

Lens ya Germanium ndi lens ya kuwala yopangidwa ndi germanium.Germanium (Ge) ndi chinthu cha crystalline chokhala ndi index yowoneka bwino kwambiri (4.002@11µm) ya zida zomwe zimagwiritsidwa ntchito kwambiri ndi infuraredi.Ilinso ndi kubalalikana kocheperako, kuuma kwakukulu ndi kachulukidwe.Chifukwa cha kufalikira kwake kwakukulu (kuposa 45% mu bandi ya 2-12 micron) ndi opaque ku UV ndi kuwala kowoneka bwino, Germanium ndiyoyenera kugwiritsa ntchito IR monga makina owonetsera kutentha, ntchito za infrared field ndi zida zowunikira molondola.

Germanium imakhudzidwanso ndi kuthawa kwa kutentha.Ndi kukula kwa kutentha, kuyamwa kumawonjezeka mofulumira kwambiri.Chifukwa cha kutha kwa kutenthaku, mandala a germanium si oyenera kugwiritsidwa ntchito potentha kuposa 100°C.

Wavelength Infrared imatha kupanga mawonekedwe osiyanasiyana a mandala a germanium okhala ndi ndege, concave, convex, aspheric and diffractive surface.Germanium ndiyotchuka kwambiri pamakina omwe akugwira ntchito m'chigawo cha 3-5 kapena 8-12µm chowonera, chokhala ndi zokutira zotsutsa (AR coating), kufalikira kwapakati kumatha kubweretsedwa ku 97.5-98.5% kumadalira bandwidth ya zokutira.Tithanso kuyika zokutira ngati diamondi (zopaka za DLC) kapena zokutira zolimba kwambiri (zopaka za HD) pamagalasi kuti titetezere ku kukanda ndi kukhudzidwa.

Wavelength infrared imapanga magalasi amtundu wamtundu wozungulira komanso wa aspheric germanium.Amatha kuyang'ana kapena kusiyanitsa kuwala komwe kukubwera kuti akwaniritse zofunikira za infrared system.Kugwiritsa ntchito kumatha kukhala kuyerekezera kwamafuta, thermograph, kukwera kwamitengo, kusanthula kwa sipekitiramu ndi zina.
