Emkhakheni wokukhiqiza amathuluzi okubona, ukunemba kwamalensi kunquma ngqo ikhwalithi yezithombe. Kusukela kumatheleskopu ezinkanyezi kuya kumathuluzi amancane, kusukela kumakhamera aphezulu kuya kumishini ye-photolithography enembile, ukusebenza okuvelele kwanoma iyiphi idivayisi yokubona kuncike ekusekelweni kwamalensi anembile kakhulu. Imishini yokubona i-granite, enezici zayo ezingenakuqhathaniswa, iba yisihluthulelo sokudala amapulatifomu okugaya amalensi anembile kakhulu, okuqhuba ukukhiqizwa kwamathuluzi okubona ezingeni elisha lokunemba.
Izinzuzo zemvelo zemishini yokunemba kwe-granite
I-Granite yasungulwa ngezinqubo ze-geological eminyakeni engamakhulu ezigidi futhi inezakhiwo zomzimba ezihlukile, okwenza ibe yinto efanelekile yokwakha amapulatifomu okugaya amalensi anembe kakhulu. Okokuqala, i-coefficient yokwanda kokushisa kwe-granite iphansi kakhulu, ngokuvamile isukela ku-5 kuya ku-7×10⁻⁶/℃, futhi cishe ayithinteki ukuguquguquka kokushisa kwemvelo. Ngesikhathi senqubo yokugaya ilensi, ukushisa okubangelwa ukusebenza kwemishini noma izinguquko ekushiseni kwemvelo ngeke kubangele ukuguqulwa okukhulu kwepulatifomu yokugaya i-granite, ngaleyo ndlela kuqinisekiswe ukuthi ukunemba kobukhulu bamalensi kuhlala kuzinzile kuyo yonke inqubo yokugaya futhi kugwenywe ukuphambuka kokugoba kwamalensi okubangelwa ukwanda nokuncipha kokushisa.
Okwesibili, i-granite inamandla amahle kakhulu okunciphisa ukudlidliza. Ukugaya ilensi ye-optical kudinga indawo yokucubungula ezinzile kakhulu. Ngisho nokudlidliza okuncane kakhulu kungabangela amaphutha ebusweni belensi. I-granite ingamunca ngempumelelo amandla okudlidliza angaphandle, inciphise ukuphazamiseka kokudlidliza ngesikhathi senqubo yokugaya, yehlise ubukhulu bokudlidliza ngo-60% kuya ku-80%, iqinisekise indawo eqondile phakathi kwethuluzi lokugaya nelensi, futhi isize ekufinyeleleni ukushelela okuphezulu kakhulu ebusweni belensi.
Ngaphezu kwalokho, i-granite inobulukhuni obuphezulu kanye nokumelana nokuguguleka okunamandla, enobulukhuni be-Mohs obungu-6 kuya ku-7. Emisebenzini yokugaya ilensi yesikhathi eside neyama-frequency aphezulu, amapulatifomu okugaya i-granite awagugi, angahlala egcina ukunemba okuzinzile, andise impilo yesevisi yemishini, futhi anciphise izindleko zokulungisa.
Ubuchwepheshe bokucubungula kahle amapulatifomu okugaya i-granite
Ukuze kusetshenziswe ngokugcwele izinzuzo zokusebenza kwe-granite, ipulatifomu yokugaya ilensi enembile kakhulu isebenzisa izinqubo zobuchwepheshe ezithuthukisiwe ngesikhathi senqubo yokukhiqiza. Ngobuchwepheshe bokugaya nokupholisha obunembile kakhulu bokulawula izinombolo, ukuthamba komphezulu wepulatifomu ye-granite kungalawulwa ngaphakathi kuka-±0.002mm/m, futhi ukugoba komphezulu kungafinyelela ezingeni le-nanometer. Le khwalithi yomphezulu enembile kakhulu inikeza indawo enembile yokubhekisela yokugaya ilensi, okuqinisekisa ukuthi amathuluzi okugaya angacubungula amalensi ngokulinganayo nangokuzinzile.
Okwamanje, enkambisweni yokuklama nokukhiqiza yesikhulumi sokugaya i-granite, izakhiwo zemishini eziqondile kanye nezinhlelo zokunyakaza ziyahlanganiswa. Isibonelo, ngokuhlanganisa iziteshi zokuqondisa ezintanta emoyeni ezinembile kakhulu kanye nezinhlelo zokushayela ze-servo motor, amathuluzi okugaya angafeza ukunyakaza okubushelelezi nokunembile epulatifomu, ngokunemba kokubeka ukunyakaza okungu-±0.005mm. Lokhu kulawula ukunyakaza okunembile kakhulu, kuhlanganiswe nokuqina kwepulatifomu ye-granite, kungahlangabezana nezidingo zokugaya zezindawo ezigobile eziyinkimbinkimbi zezinhlobo ezahlukene zamalensi. Kungakhathaliseki ukuthi amalensi aqondile, amalensi aqondile, noma amalensi angenasiphepho, ukucubungula okunembile kakhulu kungafezwa.
