Nangona iqonga legranite lisenokubonakala ngathi lilitye nje elilula, iikhrayitheriya zokukhetha zitshintsha kakhulu xa zisuka kwizicelo eziqhelekileyo zoshishino ukuya kuhlolo lwe-optical oluphezulu kunye ne-metrology. Kwi-ZHHIMG®, ukubonelela ngezinto ezichanekileyo kwiinkokheli zehlabathi kwi-semiconductor kunye ne-laser technology kuthetha ukuqonda ukuba iqonga lokulinganisa i-optical alilo nje isiseko—liyinxalenye ebalulekileyo, engenakuthethwa ngayo yenkqubo ye-optical ngokwayo.
Iimfuneko zokuhlolwa kwe-optical—eziquka umzobo wokukhulisa okuphezulu, ukuskena nge-laser, kunye ne-interferometry—zichazwa yimfuno yokususa yonke imithombo yengxolo yokulinganisa. Oku kukhokelela ekugxileni kwiimpawu ezintathu ezikhethekileyo ezahlula iqonga lokwenyani le-optical kweleshishini eliqhelekileyo.
1. Uxinano oluPhezulu lokuDamping okuNgcono okuNgalinganiyo
Kwiziseko ze-CNC zemizi-mveliso eziqhelekileyo, isinyithi esityhidiweyo okanye i-granite eqhelekileyo inokubonelela ngokuqina okwaneleyo. Nangona kunjalo, ukuseta okubonakalayo kubuthathaka kakhulu kukuhamba okuncinci okubangelwa kukungcangcazela kwangaphandle okuvela kwizixhobo zasefektri, iinkqubo zokuphatha umoya, okanye kwanezithuthi ezikude.
Kulapho isayensi yezinto ezibonakalayo iba yeyona nto ibalulekileyo khona. Iqonga le-optical lifuna i-granite enokuthintela izinto ngendlela engaqhelekanga. I-ZHHIMG® isebenzisa i-ZHHIMG® Black Granite yayo (≈ 3100 kg/m³). Le nto ixineneyo kakhulu, ngokungafaniyo ne-granite ekumgangatho ophantsi okanye ii-marble substitutes, inesakhiwo sekristale esisebenza kakuhle ekuchitheni amandla oomatshini. Injongo ayikokunciphisa nje ukungcangcazela, kodwa kukuqinisekisa ukuba isiseko sihlala singumgangatho woomatshini othuleyo, sinciphisa intshukumo phakathi kwelensi ejolise kuyo kunye nesampuli ehloliweyo kwinqanaba le-sub-micron.
2. Uzinzo oluPhezulu lobushushu ukuze kuliwe nokuguquguquka
Amaqonga emizi-mveliso aqhelekileyo anyamezela utshintsho oluncinci; ishumi leedigri zeCelsius lisenokungabalulekanga xa kugrunjwa. Kodwa kwiinkqubo ze-optical ezenza imilinganiselo echanekileyo kangangexesha elide, naluphi na uguquko lobushushu kwi-geometry yesiseko luzisa impazamo ecwangcisiweyo.
Ukuhlolwa kwe-optical, iqonga kufuneka lisebenze njengesinki yobushushu ene-coefficient ephantsi kakhulu yokwandiswa kwe-thermal (CTE). Ubunzima obuphezulu kunye noxinano lwe-ZHHIMG® Black Granite lubonelela nge-thermal inertia efunekayo yokumelana nokwandiswa okuncinci kunye nokucutheka okunokwenzeka kwigumbi elilawulwa yimozulu. Olu zinzo luqinisekisa ukuba umgama wokugxila olinganisiweyo kunye nokulungelelaniswa kwe-planar yezixhobo ze-optical zihlala zizinzile, okuqinisekisa ukuthembeka kwemilinganiselo ethatha iiyure—into engenakuphikiswana ngayo yokuhlolwa kwe-wafer enesisombululo esiphezulu okanye i-flat-panel display metrology.
3. Ukufikelela kwiNano-Level Flatness kunye neGeometric Precision
Umahluko obonakalayo kakhulu yimfuneko yokuba tyaba. Nangona isiseko esiqhelekileyo semizi-mveliso sinokufikelela kwiBanga loku-1 okanye iBanga lesi-0 tyaba (elilinganiswa kwii-microns ezimbalwa), iinkqubo ze-optical zifuna ukuchaneka kuluhlu lwe-nanometer. Eli nqanaba lokugqibelela kwejometri liyimfuneko ukubonelela ngeplani yesalathiso ethembekileyo yezigaba ezithe ngqo kunye neenkqubo ze-autofocus ezisebenza kwimigaqo yokuphazamiseka kokukhanya.
Ukufikelela nokuqinisekisa ukuba i-nanometer flatness ikumgangatho othe kratya kufuna indlela yokuvelisa eyahlukileyo ngokupheleleyo. Ibandakanya iindlela ezikhethekileyo kakhulu ezisebenzisa oomatshini abaphambili abanjengeTaiwan Nanter grinders kwaye iqinisekiswa zizixhobo ze-metrology ezintsonkothileyo ezifana neRenishaw Laser Interferometers. Le nkqubo kufuneka yenzeke kwindawo ezinzileyo kakhulu, njengeendawo zokusebenzela ze-ZHHIMG® ezilawulwa kukungcangcazela, apho kwaneentshukumo zomoya ezingabonakaliyo zincitshiswa khona.
Ngokwenyani, ukukhetha iqonga lokuchaneka kwegranite lokuhlolwa kwe-optical sisigqibo sokutyala imali kwicandelo eliqinisekisa ngokusebenzayo ukuchaneka komlinganiselo we-optical ngokwawo. Oku kufuna ukusebenzisana nomenzi ojonga isiqinisekiso se-ISO 9001 kunye nokulandeleka okubanzi kungekuko njengeempawu zokuzikhethela, kodwa njengeemfuno ezisisiseko zokungena kwihlabathi le-ultra-precision optics.
