Granite yog lub pob zeb tsis muaj zog uas tsim los ntawm quartz, feldspar thiab mica uas ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv kho qhov muag. Nws cov khoom tshwj xeeb ua rau nws yog cov khoom siv zoo tshaj plaws rau ntau yam kev siv hauv kev lag luam kho qhov muag, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov khoom siv kho qhov muag zoo xws li lo ntsiab muag, iav thiab prisms.
Ib qho ntawm qhov zoo tshaj plaws ntawm granite yog nws qhov tshwj xeeb ruaj khov. Tsis zoo li lwm cov ntaub ntawv, granite muaj thermal expansion me me, uas yog ib qho tseem ceeb rau precision optics txij li thaum txawm me ntsis deformation tuaj yeem ua rau muaj teeb meem loj hauv kev kho qhov muag. Qhov kev ruaj ntseg no ua kom ntseeg tau tias cov khoom siv kho qhov muag tswj lawv cov duab thiab kev sib haum xeeb nyob rau hauv qhov sib txawv ntawm ib puag ncig, yog li ua kom qhov tseeb thiab kev ntseeg siab ntawm cov tshuab kho qhov muag.
Tsis tas li ntawd, granite qhov ntom ntom pab nws ua kom muaj kev vibrations zoo. Thaum lub sij hawm tsim cov txheej txheem ntawm precision optics, kev co tuaj yeem cuam tshuam qhov zoo ntawm cov khoom tiav. Los ntawm kev siv granite ua lub hauv paus lossis cov qauv kev txhawb nqa, cov tuam ntxhab tuaj yeem txo cov kev vibrations, ua rau cov npoo du thiab zoo dua qhov pom tseeb. Cov cuab yeej no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov siab xws li telescopes thiab microscopes, qhov twg txawm tias qhov tsis zoo me me tuaj yeem cuam tshuam kev ua haujlwm tag nrho.
Granite txoj haujlwm ua haujlwm yog lwm yam uas ua rau nws tsim nyog rau kev siv hauv cov khoom siv optics. Txawm hais tias nws yog cov khoom siv nyuaj, kev nce qib hauv kev txiav thiab kev sib tsoo tshuab tau tso cai rau nws ua tiav cov kev zam zoo rau cov khoom siv kho qhov muag. Cov kws tshaj lij tuaj yeem tsim cov granite rau hauv cov qauv tsim tshwj xeeb, tso cai rau kev tsim cov khoom siv kho qhov muag thiab cov khoom siv los txhim kho kev ua haujlwm ntawm koj qhov kho qhov muag.
Hauv cov ntsiab lus, granite qhov ruaj khov, ntom ntom, thiab ua haujlwm ua haujlwm ua rau nws yog ib qho khoom siv tsis tseem ceeb hauv precision optical manufacturing. Raws li qhov kev thov rau kev ua haujlwm siab kho qhov muag txuas ntxiv mus ntxiv, granite lub luag haujlwm hauv kev lag luam yuav tsis muaj qhov tseem ceeb, kom ntseeg tau tias cov tuam ntxhab tuaj yeem tsim cov khoom lag luam uas ua tau raws li cov qauv nruj ntawm niaj hnub optics.
