Kwinkqubo yokufakelwa kwelensi kunye nenkqubo yokucoca, nayiphi na into enamathele, kwanamathole ee-oyile, iya konyusa izinga le-lensi, ukunciphisa ubomi beenkonzo. Ke ngoko, ezi zilumkiso kufuneka zithathwe:
I-1. Ungaze ufake iilensi ngeminwe engafakwanga. Iigloves okanye iigloves zerabha kufuneka zinxitywe.
2. Sukusebenzisa izixhobo ezibukhali ukunqanda ukukrazula i-lens.
3. Sukuchukumisa ifilimu xa ususa ilensi, kodwa ubambe umda welensi.
I-4. Iilensi kufuneka zibekwe kwindawo eyomileyo, ecocekileyo yokuvavanywa nokucoca. Umphezulu wetafile elungileyo kufuneka ubenemigca eliqela lokucoca iphepha okanye i-Swab, kunye namaphepha aliqela okucoca i-lens sponge.
5. Abasebenzisi kufuneka bakuphephe ukuthetha nge-lens kwaye bagcine ukutya, ukusela kunye nezinye izinto ezinokubakho kude nendawo yokusebenza.
Indlela yokucoca echanekileyo
Eyona njongo yenkqubo yokucoca i-lensi kukususa ungcoliseko oluvela kwiilensi kwaye alunangxaki kunye nomonakalo kwilensi. Ukuze ufezekise le njongo, umntu kufuneka asebenzise iindlela ezinobungozi. La manyathelo alandelayo ayilelwe le njongo kwaye kufuneka asetyenziswe ngabasebenzisi.
Okokuqala, kuyimfuneko ukusebenzisa ibhola yomoya ukuvuthuza ifloss kumphezulu wecandelo, ngakumbi ilensi ngamasuntswana amancinci kunye nefloss kumphezulu. Kodwa musa ukusebenzisa umoya oxinzelelweyo kumgca wemveliso, kuba lo moya uya kuba neoyile kunye namaconsi amanzi, oya kuthi enze nzulu ungcoliseko lweelensi
Inyathelo lesibini kukusebenzisa i-acetone ukucoca ilensi kancinci. I-acetone kweli nqanaba liphantse licaphukisiwe, elinciphisa ukubakho kwe-lens ungcoliseko lwe-lens. Iibhola ze-cotton ezigxunyekwe kwi-acetone kufuneka zicocwe phantsi kokukhanya kwaye zishukunyiswe kwisangqa. Nje ukuba i-swab ye-cotton imdaka, itshintshe. Ukucocwa kufuneka kwenziwe ngexesha elinye ukuphepha isizukulwana semivalo yamanzi.
Ukuba iilensi zinendawo ezimbini eziphakathi, ezinjengeelensi, umphezulu ngamnye kufuneka ucocwe ngale ndlela. Icala lokuqala kufuneka libekwe kwiphepha elicocekileyo lephepha le-lens lokukhusela.
Ukuba i-acetone ayishenxisi wonke ubumdaka, emva koko ihlambe ngeviniga. Ukucoca iviniga kusebenzisa isisombululo sokungcola ukususa ubumdaka, kodwa ungamonakalisi iilensi zamehlo. Le vilini inokuba libanga lovavanyo (linqunywe kumandla angama-50%) okanye iviniga emhlophe yekhaya ene-6% ye-acetic acid. Inkqubo yokucoca ifana nokucocwa kwe-acetone, emva koko i-acetone isetyenziselwa ukususa iviniga kwaye yome ilensi, itshintsha ibhola, itshintsha i-cotton Rall rhoqo ukuze ifumane ngokupheleleyo i-acid kunye ne-hydrate.
Ukuba umphezulu weelensi azichaphazelekanga ngokupheleleyo, ke sebenzisa ukucocwa kwePolishing. Ukucocwa kwePolimeding kukusebenzisa iBakala elihle (i-0.1m) i-Aluminium Poteling Passing.
Ulwelo oluMhlophe lusetyenziswa ngebhola yomqhaphu. Kuba oku kucoceka kwepulikisi kukhulisa umatshini, umphezulu weelensi kufuneka ucocwe kwilog ecothayo, engalunganga enoxinzelelo, hayi ngaphezulu kwemizuzwana engama-30. Hlamba umphezulu onamanzi anezinzi okanye ibhola yomqhaphu egxunyekwe emanzini.
Emva kokuba ipolili isuswe, indawo yelensi icocwe nge-Iyopropyl yotywala. I-Iyopropyl Ethanol ibambe ipolish eseleyo kwi-Polish eshiyekileyo emanzini, emva koko isuse ngebhola yomqhaphu egxunyekwe kwi-acetone. Ukuba kukho nakwakhona intsalela phezu komhlaba, ihlambe kwakhona ngotywala kunye ne-acetone de icoceke.
Ewe kunjalo, abanye oomonakalo kunye ne-lens ayinakususwa ngokucoca, ngakumbi ifilimu yefilimu efakelwe yintsimbi kunye nobumdaka, ekuphela kwendlela yokutshintsha ilensi.
Indlela efanelekileyo yokufaka
Ngexesha lenkqubo yokufaka, ukuba indlela ayichanekanga, iilensi ziya kungcoliswa. Ke ngoko, iinkqubo zokusebenza ezikhankanywe ngaphambili kufuneka zilandelwe. Ukuba inani elikhulu leelensi kufuneka lifakwe kwaye lisuswe, kuyimfuneko ukuba uyila umgaqo wokufezekisa umsebenzi. Iqela elikhethekileyo linokunciphisa inani lokunxibelelana nelensi, ngaloo ndlela kuncitshiswa umngcipheko we-lens okanye umonakalo.
Ukongeza, ukuba ilensi ayifakwanga ngokuchanekileyo, inkqubo yase-laser ayisebenzi kakuhle, okanye yonakele. Zonke ii-co2 ze-co2 lase-Iser kufuneka zibekwe kwicala elithile. Ke umsebenzisi kufuneka aqinisekise ukuqhelaniswa nelensi. Umzekelo, umphezulu ophezulu wesibuko esipilini semveliso kufuneka ube ngaphakathi kwe-cavity, kwaye umphezulu ophezulu ophezulu kufuneka angaphandle kwe-cavity. Ukuba oku kubuyiswa, i-laser iya kuvelisa i-right okanye i-larness ephantsi kakhulu. Icala leConvex le-Convex ye-lensi egxile kwi-lens kwi-cavity, kunye necala lesibini ngokusebenzisa i-lensi yi-cocave okanye iflethi, ephethe umsebenzi. Ukuba ibuyiselwe umva, ugxininiso luya kuba lukhulu kwaye umgama wokusebenza uza kutshintsha. Kwizicelo zokusika, ezikhokelela kwi-slits enkulu kunye nesantya esicothayo esicothayo. Ababona luhlobo lwesithathu oluqhelekileyo lwelensi, kwaye ufakelo lwabo lubalulekile. Ewe kunjalo, kunye nesibonisi kulula ukubonisa lowo umfune. Ngokucacileyo, icala lokudinisa lijonge i-laser.
Ngokubanzi, abavelisi baya kuphawula imiphetho ukunceda ukuchonga umphezulu. Ngokwesiqhelo uphawu luphawu, kwaye utolo lukhomba kwicala elinye. Bonke abavelisi be-lens banenkqubo yokufaka ilebheli. Ngokubanzi, kwizibuko kunye nezibuko zezibuko kunye nezibuko, utolo lukhomba kwelinye icala lokuphakama. Ngeelensi, i-arrow ithi kwi-concave okanye kumgangatho othe tyaba. Ngamanye amaxesha, ilebheli ye-lens iya kukukhumbuza ngentsingiselo yelebheli.
