99.999% Al2O3 sapphire boule monocrystal rauemi mārama
He rauemi ahurei te hapaira e whakamahia whānuitia ana i roto i te ahumahi i ēnei rā. Ko te hapaira te matū tino mārō, tuarua i te taimana, he 9 te pakeke o te Mohs. Ehara i te mea he ātete noa ki ngā karawarawa me ngā pakaru, engari ki ētahi atu matū pērā i te waikawa me te kawakore, ā, he kaha ake i ētahi atu rauemi whatu. Nō reira, he pai mō te tukatuka haurua-ira me te matū. Me te ira rewa tata ki te 2050°C, ka taea te whakamahi i te hapaira i roto i ngā tono pāmahana teitei tae atu ki te 1800°C, ā, he teitei ake tōna pumau wera i tērā o tētahi atu rauemi whatu. Hei tāpiri, he mārama te hapaira mai i te 180nm ki te 5500nm, ā, nā tēnei whānuitanga o ngā āhuatanga mārama whatu ka waiho te hapaira hei rauemi pai rawa atu mō ngā pūnaha whatu infrared me te ultraviolet. Hei whakamutunga, engari ehara i te mea iti rawa, he rauemi rongonui hoki te hapaira i roto i te ahumahi whakapaipai, he mea motuhake nā tōna parakore teitei, te tuku mārama me te pakeke. Ka taea te whakarerekē i te tae o te hapaira kia rite ki ngā whakaritenga rerekē, ka whakarato i te whānuitanga o ngā kōwhiringa ki ngā kiritaki.
