Chifukwa chiyani musankhe zenera la germanium la thermometer ya infrared

Nthawi zambiri, galasi la germanium limagwiritsidwa ntchito ngati zenera la chithunzithunzi cha infrared thermal kuti ateteze makina owoneka bwino komanso chowunikira cha infrared.Komabe, chifukwa refractive index ya zinthu za germanium ndi 4, kugwiritsa ntchito mwachindunji kungayambitse kutayika kwakukulu kwa chizindikirocho.Pofuna kupititsa patsogolo mphamvu yotumizira ma siginecha a infrared, galasi la germanium liyenera kuphimbidwa ndi mafilimu oyenerera kuti apititse patsogolo kufalikira ndi kuteteza pamwamba pa mandala a germanium.

Galasi ya Germanium laminated ili ndi kuwala kwabwino kwambiri pa 2-16um, ndipo mawonekedwe ake ndi okhazikika.Sikophweka kuwonetsera ndi hydroxide, asidi asidi ndi madzi.Thermometer ya infrared ndi chojambula chotenthetsera chiyenera kukhala ndi fyuluta yapakati komanso yakutali.Thermometer ya infrared ndi chojambula chotenthetsera nthawi zambiri chimagwira ntchito mu gulu la 2-13um, pomwe galasi la germanium laminated limangokhala ndi kutumizirana bwino kwambiri mu infrared yakutali.Kutumiza kwa magalasi wamba mugululi ndikotsika kwambiri, kotero sikungamalizidwe

Kuonjezera apo, filimu ya kuwala yomwe imayikidwa pa galasi la germanium laminated imatha kuonjezera kwambiri kufalikira kwake ndikuchepetsa kufalikira kwa galasi la germanium laminated.Galasi laminated la Germany silidutsa mu gulu lowala losaoneka.Pazithunzi zina zotentha, anthu amathanso kugwiritsa ntchito makristalo a silicon m'malo mwa galasi la germanium laminated.Gulu lozungulira la makristalo a silicon silitalikirana ndi galasi la germanium laminated.

Silicon (Si) polycrystalline silikoni ndi organic mankhwala pulasitiki zopangira ndi mphamvu kwambiri ndi madzi osasungunuka.Ili m'gulu la 1-7 μ M-band ili ndi ma transmittance abwino kwambiri.Kuphatikiza apo, ili mu gulu lakutali la infrared 300-300 μ M ilinso ndi kuwala kwabwino kwambiri, komwe ndi mawonekedwe omwe zida zina zowoneka bwino komanso zosawoneka bwino zilibe.

Silicon (Si) polycrystalline silikoni nthawi zambiri imagwiritsidwa ntchito pa 3-5 μ Chifukwa cha kutentha kwake kwabwino komanso kutsika kwapang'onopang'ono, ndizinthu zodziwika bwino zopangira magalasi owoneka bwino a laser, ma thermometers a infrared ndi magalasi a infrared optical laser.

Galasi yaku Germany imagwiritsidwa ntchito pazenera la infrared thermal imager ndi infrared thermometer.Gulu la 8-14um limaganiziridwa makamaka.Kutumiza kwa galasi la germanium popanda zokutira ndi 40-50% yokha, pomwe kutumizira kwa galasi la germanium lokutidwa ndi filimu yowonetsera kumatha kufika 90%.Kuphatikiza apo, makasitomala ambiri amafunikiranso filimu ya kaboni ya diamondi ya DLC pagalasi la germanium kuti alimbikitse kuuma kwa galasi la germanium ndikukwaniritsa kuphulika kwamphamvu.
