    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 no ka hana ʻana 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 hui holoʻokoʻa o 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 wikiwiki ka helu kuhikuhi refractive o Germanium me ka mahana a lilo ka mea i opaque ma nā lōʻihi hawewe a pau ma luna iki o 350K i ka wā e kahe ana ka ʻāwaha me nā electron thermal.
