Kauj ruam Qhov Dia25.4 × 2.0mmt Sapphire optical lens qhov rais
Cov ncauj lus kom ntxaws
Cov khoom siv tshuaj lom neeg ntawm sapphire yog qhov ruaj khov thiab tsis corroded los ntawm acids thiab alkalis. Lub hardness ntawm sapphire yog siab heev, nrog ib tug Mohs hardness ntawm 9, thib ob tsuas yog lub hardest pob zeb diamond. Nws muaj lub teeb kis tau zoo, thermal conductivity thiab hluav taws xob rwb thaiv tsev, zoo mechanical thiab mechanical zog, thiab muaj cov yam ntxwv ntawm hnav tsis kam thiab cua yaig kuj. Qhov siab tshaj plaws ua haujlwm kub yog 1900 ℃.
Vim tias cov khoom siv zoo nkauj zoo nkauj sapphire siv lead ua muaj lub teeb pom kev zoo hauv 170nm ~ 6000 nm band, infrared transmittance yuav luag tsis hloov nrog qhov kub, yog li cov khoom siv kho qhov muag thiab infrared transmittance optical qhov rais ua los ntawm cov khoom zoo nkauj sapphire yog tsim. ntawm cov khoom zoo sapphire. Nws tau siv tag nrho hauv cov khoom siv tub rog hmo ntuj pom infrared, qhov ntsuas kub tsis tshua muaj chaw soj ntsuam chaw nres nkoj, cov cuab yeej ua haujlwm siab rau navigation, aerospace thiab lwm yam haujlwm.
Cov yam ntxwv thiab kev siv ntawm sapphire
1, Sapphire nrog nws cov kev ua tau zoo tshaj plaws, dhau los ua cov khoom siv oxide substrate ntau tshaj plaws (cov ntaub ntawv substrate)
2, Optical Cheebtsam, saib daim iav, optical qhov rais, nrhiav kom pom qhov rais thiab nws daim ntawv thov
3, Sapphire fiber ntau sensor thiab nws daim ntawv thov
4, Doped sapphire ib leeg siv lead ua thermal (lub teeb) luminescence khoom thiab nws daim ntawv thov
