Germanium (Ge)
Loaʻa i ka Germanium kahi hiʻohiʻona uahi hina ʻeleʻele me kahi kuhikuhi refractive kiʻekiʻe o 4.024 ma 10.6 µm & haʻahaʻa optical dispersion.Hoʻohana ʻia ʻo Ge e hana i nā prisms Attenuated Total Reflection (ATR) no ka spectroscopy.ʻO kāna kuhikuhi kuhikuhi refractive e hana i ka 50% beamsplitter kūlohelohe maoli me ka ʻole o ka pono o nā uhi.Hoʻohana nui ʻia ʻo Ge ma ke ʻano he substrate no ka hana ʻana i nā kānana optical.Hoʻopili ʻo Ge i ka hui wela 8 - 14 µm 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 optics mua paʻakikī.Eia kekahi, ʻaʻole inert ʻo Ge i ka ea, ka wai, nā alkalis, a me nā waikawa (koe wale ka nitric acid), loaʻa iā ia ka paʻa nui me kahi Knoop Hardness (kg/mm2): 780.00 e ʻae iā ia e hana maikaʻi no nā optics kahua i nā kūlana paʻakikī.ʻO nā waiwai hoʻoili o Ge, ʻaʻole i hoʻouna ʻia ma 200 °C a ʻaʻole hiki ke hoʻouna ʻia ma 200 °C.

Manaʻo kōkua: I ka hana ʻana me ka Germanium, pono e hoʻokomo i nā mīkina lima, no ka mea he mea weliweli ka lepo mai ka mea.No kou palekana, e ʻoluʻolu e hahai i nā kaʻina kūpono a pau, me ke komo ʻana i nā mīkina lima i ka wā e lawelawe ai i kēia mea a me ka holoi pono ʻana i kou mau lima ma hope.
No ka ʻikepili kikoʻī hohonu hou aku, e ʻoluʻolu e nānā i kā mākou catalog optics e ʻike i kā mākou koho piha o nā optics i hana ʻia mai germanium.
