Cov theem granite yog cov cuab yeej tseem ceeb hauv kev ua haujlwm precision engineering, tshwj xeeb tshaj yog hauv kev sim thiab calibration ntawm cov khoom siv optical. Ua los ntawm cov granite ntuj, cov theem no muab qhov chaw ruaj khov thiab tiaj tus, uas yog qhov tseem ceeb rau kev ua tiav cov kev ntsuas tseeb hauv kev siv optical.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov granite platforms yog lawv qhov tiaj tiaj zoo kawg nkaus. Cov nplaim ntawm cov platforms no tau ua tib zoo tshuab kom tiaj tiaj heev, feem ntau yog nyob rau hauv ob peb microns. Qib kev raug no yog qhov tseem ceeb thaum kuaj cov khoom siv kho qhov muag xws li lens thiab iav, vim tias txawm tias qhov kev hloov pauv me me tuaj yeem ua rau muaj qhov yuam kev loj hauv kev ua tau zoo. Los ntawm kev muab lub dav hlau siv tau zoo, granite platforms xyuas kom meej tias cov khoom siv kho qhov muag tuaj yeem sib dhos thiab ntsuas tau raws li qhov tseeb.
Granite kuj paub txog nws qhov ruaj khov thiab tiv taus kev hnav. Tsis zoo li lwm cov ntaub ntawv uas yuav deform lossis hnav dhau sijhawm, granite tswj nws qhov kev ncaj ncees, kom ntseeg tau tias qhov chaw sim tseem sib xws dhau sijhawm ntev. Qhov kev ruaj khov no yog qhov tseem ceeb tshwj xeeb hauv kev sim kho qhov muag, qhov twg kev ntsuas rov ua dua yuav tsum tsim cov txiaj ntsig txhim khu kev qha. Granite cov khoom tseem ceeb kuj ua rau nws tsis tshua muaj kev cuam tshuam rau kev nthuav dav thermal, uas tuaj yeem cuam tshuam rau qhov tseeb ntawm kev ntsuas. Qhov no yog qhov tseem ceeb hauv cov chaw uas qhov kub hloov pauv ntau.
Tsis tas li ntawd xwb, cov platform granite feem ntau siv nrog ntau yam khoom siv kuaj pom kev zoo, xws li interferometers thiab autocollimators. Cov khoom siv no xav tau lub platform ruaj khov kom ua haujlwm tau zoo, thiab cov platform granite muab kev txhawb nqa tsim nyog. Kev sib xyaw ua ke ntawm granite qhov chaw tiaj tus thiab kev khov kho tso cai rau kev sib dhos thiab kev tso chaw ntawm cov khoom siv kho qhov muag, ua rau kev sim thiab kev soj ntsuam raug.
Xaus lus, cov platform granite ua lub luag haujlwm tseem ceeb hauv kev sim cov khoom siv optical. Lawv qhov tiaj tus, ruaj khov, thiab ruaj khov ua rau lawv yog cov khoom siv tseem ceeb rau kev ua kom raug thiab ntseeg tau ntawm kev ntsuas optical, thaum kawg pab txhawb rau kev nce qib ntawm cov thev naus laus zis optical.
