Isinyathelo Izimbobo Dia25.4×2.0mmt amawindi e-Sapphire optical lens
Ulwazi Oluningiliziwe
Amakhemikhali esafire azinzile kakhulu futhi awagqwali ngama-asidi nama-alkali. Ukuqina kwesafire kuphezulu kakhulu, ngokuqina kwe-Mohs okungu-9, okwesibili ngemuva kwedayimane elinzima kakhulu. Inokuhanjiswa kokukhanya okuhle, ukuguquguquka okushisayo kanye nokufakwa kukagesi, izakhiwo ezinhle zemishini nemishini, futhi inezici zokumelana nokugqoka kanye nokumelana nokuguguleka komoya. Izinga lokushisa eliphezulu lokusebenza ngu-1900 ℃.
Ngenxa yokuthi izinto ezisezingeni eliphakeme zokwenziwa kwekristalu yesafire zinokudluliswa okuhle kokukhanya ebhendini engu-170nm ~ 6000 nm, ukudluliswa kwe-infrared cishe akushintshi nezinga lokushisa, ngakho-ke izingxenye ezibonakalayo kanye ne-infrared transmittance optical Windows eyenziwe ngesafire yokwenziwa yekhwalithi ephezulu yenziwa. yekhwalithi ephezulu yesafire yokwenziwa. Isetshenziswe ngokugcwele emishinini ye-infrared yombono wamasosha wasebusuku, itheku lokubuka elabhorethri lokushisa eliphansi, amathuluzi anembe kakhulu okuzulazula, i-aerospace nezinye izinkambu.
Izici kanye nokusetshenziswa kwesafire
I-1, iSapphire ngokusebenza kwayo okuhle kakhulu, iba yizinto ezisetshenziswa kakhulu ze-oxide substrate (izinto ezingaphansi)
2, Izingxenye ze-Optical, isibuko sewashi, iwindi elibonakalayo, iwindi lokubona kanye nokusebenza kwalo
3, inzwa yefiber yeSapphire kanye nokusebenza kwayo
4, I-Doped sapphire single crystal thermal (light) luminescence material kanye nokusetshenziswa kwayo
