ʻO ka Germanium ma ke ʻano he aniani mono i hoʻohana mua ʻia i ka semi-conductor ʻaʻole absorptive ma 2μm a 20μm IR māhele.Hoʻohana ʻia ma ʻaneʻi ma ke ʻano he ʻāpana optical no nā noi māhele IR.
ʻO Germanium kahi mea helu helu kiʻekiʻe i hoʻohana ʻia e hana i nā prisms Attenuated Total Reflection (ATR) no ka spectroscopy.ʻO kāna helu helu refractive ka mea e hana ai ʻo Germanium i ka 50% beamsplitter kūlohelohe me ka ʻole o ka pono o nā uhi.Hoʻohana nui ʻia ʻo Germanium ma ke ʻano he substrate no ka hana ʻana i nā kānana optical.Hoʻopili ʻia ka Germanium i ka 8-14 micron thermal band a hoʻohana ʻia i nā ʻōnaehana lens no ke kiʻi wela.Hiki ke hoʻopili ʻia ʻo Germanium me AR me ka Diamond e hana ana i kahi optic mua paʻakikī.
Hoʻoulu ʻia ʻo Germanium me ka hoʻohana ʻana i ka ʻenehana Czochralski e kahi liʻiliʻi o nā mea hana ma Belgium, USA, Kina a me Rusia.Hoʻololi koke ka helu helu refractive o Germanium me ka mahana a lilo ka mea i opaque ma nā hawewe a pau ma luna iki o 350K i ka wā e kahe ana ka ʻāwaha me nā electron thermal.
Noi:
• Pono no nā noi kokoke-IR
• Broadband 3 i ka 12 μm anti-reflection coating
• Pono no nā noi e koi ana i ka hoʻopuehu haʻahaʻa
• Nui no ka mana haʻahaʻa CO2 laser noi
Hiʻona:
• 'A'ole hiki ke ho'ouna 'ia kēia mau puka makani germanium ma ka 'āpana 1.5µm a i 'ole ma lalo, no laila, aia kona ho'ohana nui ma nā 'āpana IR.
• Hiki ke hoʻohana ʻia nā puka makani Germanium i nā hoʻokolohua infrared like ʻole.
