Safire (Al2O3)
Safire (Al2O3) ikristaro imwe chete aluminium oxide (Al2O3) neMohs kuoma kwe9, ndechimwe chezvinhu zvakaoma zvikuru. Uku kuoma kwakanyanyisa kwesafire kunoita kuti zviome kupukuta uchishandisa hunyanzvi hunyanzvi. High optical quality inopedzisa pasafire haisi nguva dzose inogoneka. Sezvo Sapphire yakasimba kwazvo uye iine simba rakanaka remuchina, inogara ichishandiswa semahwindo zvinhu uko kukwenya kuramba kunodiwa. Iyo yakakwirira yekunyungudika, yakanaka yekupisa conductivity uye kuderera kwekuwedzera kwemafuta kunopa kuita kwakanakisa munzvimbo dzekushisa kwepamusoro. Sapphire ikemikari inert uye hainyunguriki mumvura, maasidhi akajairika, uye alkalis kune tembiricha inosvika 1,000 °C. Inowanzo shandiswa muIR laser masisitimu, spectroscopy, uye yakaomarara ezvakatipoteredza michina.

Grafu
Girafu rekurudyi inzira yekufambisa ye10 mm gobvu, isina kuvharwa nesafire substrate
Mazano: Sapphire ine birefringent zvishoma, chinangwa chakajairika IR mahwindo anowanzo kuchekwa nenzira isina kujairika kubva kukristaro, zvisinei chinongedzo chinosarudzwa kune chaiwo maapplication apo iyo birefringence inyaya. Kazhinji izvi zvinenge zvine optic axis pa90 madhigirii kuenda pamusoro pendege uye inozivikanwa se "zero degree" zvinhu. Synthetic optical sapphire haina ruvara.
Kuti uwane rumwe ruzivo rwakadzama rwe data, ndapota tarisa yedu katalogi optics kuti uone yedu yakazara sarudzo yeoptics yakagadzirwa nesafire.
