Muminda yekuedza kwekuona zvakanyatsonaka uye kugadzira zvinhu zvepamusoro-soro, kugadzikana kwemakona padanho re0.01μrad chiratidzo chakakosha. Mapuratifomu ekuona egranite, ane hunhu hwawo hwezvinhu uye kubatana kwetekinoroji, ave chinhu chikuru chekutakura zvinhu kuti zvive neunyanzvi hwakanyanya.
Zvakanakira zvezvinhu zvinoisa hwaro hwakasimba. Granite, sedombo reigneous rakaumbwa ne geology kwemazana emamiriyoni emakore, inozivikanwa nekuwanda kwaro kwakaderera kwekuwedzera kwekupisa, iyo iri hafu yesimbi uye chikamu chimwe muzvina chearuminiyamu. Kana tembiricha ikachinja ne1℃, chikamu chegranite chakareba mita imwe chinokura nema micrometer matanhatu chete, nepo chikamu chearuminiyamu chichikura nema micrometer makumi maviri nematatu. Izvi zvinodzivirira kutsauka kwekona kunokonzerwa nekushanduka kwekupisa. Panguva iyi, kushanda kwayo kwakanaka kwekudzikisa mvura kunogona kukurumidza kuderedza kudedera kwekunze, kuchengetedza puratifomu iri mumamiriro ekumira uye kuderedza kupindirana nezvikamu zve optical.
Dhizaini chaiyo yechivakwa inowedzera kuomarara. Puratifomu yegranite optical, mushure mekugadzirwa kwechimiro chemuchina chakagadziridzwa, yakasimbisa kuomarara zvakanyanya uye inogona kudzivirira kushanduka kwemutoro zvinobudirira. Kururama kwayo pakugadzirisa pamusoro kunosvika padanho repamusoro muindasitiri. Tichifunga nezvekururama kwe00-level kunoenderana nechiyero cheGB4987-85 semuenzaniso, kushivirira kwekutsetseka kunongova 2×(1 + d/1000)μm (d ndiyo kureba kwedivi), zvichipa referensi yekuiswa kwakatwasuka zvakanyanya yemidziyo ye optical.
Kuenzanisa kwakasimba kunowanikwa kuburikidza nekushandira pamwe chete kwetekinoroji. Kana yakashongedzwa nemasisitimu epamusoro ekuparadzanisa vibration akadai sema air springs kana magnetic levitation, granite platform inogona kuparadzanisa vibration yakaderera uye yakakwira. Ichiwedzerwa nemidziyo yekuyera yakanyatsojeka senge laser interferometers, shanduko dzeAngle dzinotariswa munguva chaiyo. Kana kutsauka kwacho kwapfuura chiyero che0.01μrad, system yekudzora mhinduro inobva yatanga nzira yekugadzirisa zvakanaka kuti ive nechokwadi chekuti platform inogara iri mumamiriro akakodzera uye akagadzikana.
Kubva pachinhu chakakosha kusvika pakusimbisa tekinoroji, granite optical platform, ine kugadzikana kwekupisa, kuramba kuzununguka uye mabhenefiti ekugadzirisa nemazvo sepakati payo, pamwe chete nehunyanzvi hwekudzora, yakabudirira kupfuura nepakati pe 0.01μrad precision threshold uye inoshandiswa zvakanyanya muminda yemazuva ano senge photolithography, astronomical observation uye laser measurement, ichikurudzira kutsvagisa nekugadzira high-precision optics kusvika pakukwirira kutsva.
