Granite theem yog cov cuab yeej tseem ceeb hauv kev ua haujlwm ntawm precision engineering, tshwj xeeb tshaj yog nyob rau hauv kev sim thiab calibration ntawm optical Cheebtsam. Ua los ntawm ntuj granite, cov theem no muab qhov chaw ruaj khov thiab tiaj tus, uas yog qhov tseem ceeb rau kev ua tiav kev ntsuas qhov tseeb hauv cov ntawv thov kho qhov muag.
Ib qho ntawm qhov zoo tshaj plaws ntawm granite platforms yog lawv qhov tshwj xeeb flatness. Qhov chaw ntawm cov platforms no tau ua tib zoo ua kom zoo nkauj heev, feem ntau nyob rau hauv ob peb microns. Qhov kev txiav txim siab no yog qhov tseem ceeb thaum kuaj cov khoom siv kho qhov muag xws li lo ntsiab muag thiab tsom iav, vim tias qhov sib txawv me ntsis tuaj yeem ua rau muaj kev ua yuam kev loj. Los ntawm kev muab lub dav hlau siv txhim khu kev qha, granite platforms xyuas kom meej tias cov khoom siv kho qhov muag tuaj yeem ua kom raug thiab ntsuas.
Granite tseem paub txog nws cov kav ntev thiab tsis kam hnav. Tsis zoo li lwm yam ntaub ntawv uas yuav deform los yog hnav thaum lub sij hawm, granite tuav nws txoj kev ncaj ncees, kom ntseeg tau tias qhov kev ntsuam xyuas saum npoo tseem zoo ib yam nyob rau lub sij hawm ntev. Qhov kev ruaj ntseg no yog qhov tseem ceeb tshwj xeeb hauv kev sim kho qhov muag, qhov uas rov ntsuas dua yuav tsum tsim cov txiaj ntsig txhim khu kev qha. Granite cov khoom siv los kuj ua rau nws tsis tshua muaj kev cuam tshuam rau thermal expansion, uas tuaj yeem cuam tshuam qhov ntsuas qhov tseeb. Qhov no feature yog ib qho tseem ceeb nyob rau hauv ib puag ncig uas qhov kub thiab txias hloov tau tshwm sim.
Tsis tas li ntawd, granite platforms feem ntau siv nrog ntau yam khoom siv kho qhov muag, xws li interferometers thiab autocollimators. Cov khoom siv no xav tau lub platform ruaj khov kom ua haujlwm tau zoo, thiab granite platforms muab kev txhawb nqa tsim nyog. Kev sib xyaw ua ke ntawm granite lub tiaj tiaj thiab rigidity tso cai rau kev ua kom zoo thiab qhov chaw ntawm cov khoom siv kho qhov muag, ua kom yooj yim rau kev ntsuam xyuas thiab kev ntsuam xyuas.
Hauv kev xaus, granite platforms ua lub luag haujlwm tseem ceeb hauv kev kuaj qhov muag. Lawv qhov sib txawv tsis sib xws, durability, thiab ruaj khov ua rau lawv yog cov khoom siv tsis tseem ceeb rau kev ua kom qhov tseeb thiab kev ntseeg siab ntawm kev ntsuas kho qhov muag, thaum kawg ua rau kev nce qib ntawm kev siv tshuab kho qhov muag.
