Emkhakheni wokukhiqiza insimbi yokubona, ukunemba kwamalensi kunquma ngokuqondile ikhwalithi yesithombe. Kusukela kuzibonakude zezinkanyezi kuya kumathuluzi amancane, kusukela kumakhamera asezingeni eliphezulu ukuya emishinini ye-photolithography enembayo, ukusebenza okuvelele kwawo wonke amadivaysi okubona kuncike ekusekelweni kwamalensi anembe kakhulu. Imishini yokunemba ye-Granite, enezici zayo ezingenakuqhathaniswa, iba ukhiye wokudala amapulatifomu wokugaya amalensi anembayo, okuqhuba ukukhiqizwa kwezinsimbi zokubona ezingeni elisha lokunemba.
Izinzuzo zemvelo zemishini yokunemba ye-granite
I-Granite yakhiwa ngezinqubo ze-geological phakathi namakhulu ezigidi zeminyaka futhi inezinto ezibonakalayo eziyingqayizivele, okuyenza ibe yinto ekahle yokwakha amapulatifomu okugaya amalensi anembayo. Okokuqala, i-coefficient yokunwetshwa okushisayo kwegwadle iphansi kakhulu, ngokuvamile isukela ku-5 ukuya ku-7×10⁻⁶/℃, futhi ayithinteki ukushintshashintsha kwezinga lokushisa kwemvelo. Phakathi nenqubo yokugaya ilensi, ukushisa okukhiqizwe ukusebenza kwemishini noma ukushintsha kwezinga lokushisa kwemvelo ngeke kubangele ukuguqulwa okuphawulekayo kweplathifomu yokugaya igwadle, ngaleyo ndlela kuqinisekiswe ukuthi ukunemba kobukhulu bamalensi kuhlala kuzinzile kuyo yonke inqubo yokugaya futhi kugwema ukuchezuka kokugoba kwamalensi okubangelwa ukwanda nokufinyela okushisayo.
Okwesibili, i-granite inokusebenza okuhle kakhulu kokudambisa ukudlidliza. Ukugaya i-Optical lens kudinga indawo yokucubungula ezinzile kakhulu. Ngisho nokudlidliza okuncane kungabangela ukonakala endaweni yelensi. I-Granite ingakwazi ukumunca ngempumelelo amandla okudlidliza angaphandle, inciphise ukuphazamiseka kokudlidliza phakathi nenqubo yokugaya, yehlise i-amplitude yokudlidliza ngo-60% kuya ku-80%, iqinisekise ukuma okuhlobene okunembile phakathi kwethuluzi lokugaya nelensi, futhi isize ukuzuza ukushelela okuphezulu okuphezulu endaweni yelensi.
Ukwengeza, i-granite inobunzima obukhulu nokumelana nokugqoka okuqinile, ngokuqina kwe-Mohs kwe-6 kuya ku-7. Emisebenzini yokugaya i-lens yesikhathi eside kanye ne-high-frequency, amapulatifomu okugaya ama-granite awakwazi ukugqoka nokudiliza, angakwazi njalo ukugcina ukunemba okuzinzile, ukwandisa impilo yesevisi yemishini, nokunciphisa izindleko zokulondoloza.
Ubuchwepheshe bokucubungula okunembayo kwamapulatifomu e-granite okugaya
Ukuze kusetshenziswe ngokugcwele izinzuzo zokusebenza kwegwadle, inkundla yokugaya ilensi enembayo ephezulu isebenzisa izinqubo zobuchwepheshe ezithuthukisiwe phakathi nenqubo yokukhiqiza. Ngokulawula izinombolo ukugaya okunembe kakhulu kanye nobuchwepheshe bokupholisha, ukucaba kwendawo yesikhulumi se-granite kungalawuleka ngaphakathi kuka-±0.002mm/m, futhi ukuhwaqaza kwendawo kungafinyelela izinga le-nanometer. Le khwalithi ephezulu enembayo inikeza indawo eyireferensi enembile yokugaya ilensi, iqinisekisa ukuthi amathuluzi okugaya angakwazi ukucubungula amalensi ngokulinganayo nangokuzinzile.
Phakathi naleso sikhathi, ekuklanyeni nasekukhiqizeni isiteji sokugaya i-granite, izakhiwo eziqondile zemishini kanye nezinhlelo zokunyakaza zihlangene. Isibonelo, ngokuhlanganisa ama-rail omhlahlandlela antantayo anembayo ephezulu kanye nesistimu ye-servo motor drive, amathuluzi okugaya angafinyelela ukunyakaza okushelelayo nokunemba endaweni yesikhulumi, ngokunemba kokuma kokunyakaza okungu-±0.005mm. Lokhu kulawulwa kokunyakaza okunembe kakhulu, kuhlanganiswe nokuzinza kweplathifomu yegwadle, kungahlangabezana nezidingo zokugaya zezindawo eziyinkimbinkimbi ezigobile zezinhlobo ezahlukene zamalensi. Noma ngabe ama-concave lens, ama-convex lens, noma amalensi aspheric, ukucubungula okunemba okuphezulu kungafinyelelwa.
