Sapphire (Al2O3)
Sapphire (Al2O3) ʻo ia kahi aniani alumini oxide (Al2O3) me ka paʻakikī Mohs o 9, ʻo ia kekahi o nā mea paʻakikī loa. ʻO kēia paʻakikī paʻakikī o ka sapphire ka mea paʻakikī i ka poli me ka hoʻohana ʻana i nā ʻenehana maʻamau. ʻAʻole hiki i nā manawa a pau ka hoʻopau ʻana i ka maikaʻi optical kiʻekiʻe ma ka sapphire. No ka mea ʻoi loa ka lōʻihi o Sapphire a loaʻa iā ia ka ikaika mechanical maikaʻi, hoʻohana mau ʻia ʻo ia ma ke ʻano he puka aniani kahi e koi ʻia ai ke kūʻē ʻana. ʻO kona wahi hoʻoheheʻe kiʻekiʻe, ka conductivity thermal maikaʻi a me ka hoʻonui haʻahaʻa haʻahaʻa hāʻawi i ka hana maikaʻi loa ma nā wahi wela kiʻekiʻe. ʻAʻole hiki ke hoʻoheheʻe ʻia ka Sapphire i ka wai, nā ʻakika maʻamau, a me nā alkali no nā mahana a hiki i 1,000 °C. Hoʻohana maʻamau ia i nā ʻōnaehana laser IR, spectroscopy, a me nā mea hana kaiapuni.

Kiʻikuhi
ʻO ka pakuhi ʻākau ka pihi hoʻouna o 10 mm mānoanoa, ʻaʻole i uhi ʻia ka sapphire substrate
Manaʻo kōkua: ʻOki ʻia nā puka aniani IR kumu maʻamau mai ke aniani, akā naʻe, koho ʻia kahi ʻano no nā noi kikoʻī kahi i pilikia ai ka birefringence. ʻO ka mea maʻamau kēia me ka axis optic ma 90 degere i ka mokulele honua a ʻike ʻia ʻo "zero degere". ʻAʻohe kala o ka sapphire optical synthetic.
No ka ʻikepili kikoʻī hohonu, e ʻoluʻolu e nānā i kā mākou papa inoa optics e ʻike i kā mākou koho piha o nā optics i hana ʻia mai ka sapphire.
