1. Tokiso ea lintho tse tala:
Ho bohlokoa ho khetha lisebelisoa tse tala tse loketseng ho netefatsa boleng ba likarolo tsa optical. Tlhahisong ea sejoale-joale ea optical, khalase ea optical kapa polasetiki ea optical hangata e khethoa e le thepa ea mantlha. Khalase ea Optical e tumme ka phetisetso ea eona e phahameng ea khanya le botsitso, e fana ka ts'ebetso e ikhethang ea optical bakeng sa lits'ebetso tse nepahetseng haholo le tse sebetsang hantle joalo ka li-microscopes, libonela-hōle le lilense tsa kh'amera tsa premium.
Lisebelisoa tsohle tse tala li hlahlojoa ka mokhoa o thata pele li kena ts'ebetsong ea tlhahiso. Sena se kenyelletsa ho lekola likarolo tsa bohlokoa joalo ka ponaletso, homogeneity, le index ea refractive ho netefatsa hore e lumellana le litlhaloso tsa moralo. Bothata bofe kapa bofe bo fokolang bo ka lebisa litšoantšong tse sothehileng kapa tse lerootho, tse ka senyang tšebetso ea sehlahisoa sa ho qetela. Ka hona, taolo e matla ea boleng e bohlokoa ho boloka maemo a holimo ho sehlopha ka seng sa thepa.
2. Ho Seha le ho Bopa:
Ho ipapisitsoe le litlhaloso tsa moralo, lisebelisoa tsa ho itšeha tsa profeshenale li sebelisoa ho bopa thepa e tala ka nepo. Ts'ebetso ena e hloka ho nepahala ho phahameng haholo, kaha le ho kheloha ho honyenyane ho ka ama haholo ts'ebetso e latelang. Mohlala, ha ho etsoa lilense tsa optical tse nepahetseng, liphoso tsa motsotso li ka etsa hore lense eohle e se sebetse. Ho fihlela boemo bona ba ho nepahala, tlhahiso ea sejoale-joale ea optical hangata e sebelisa lisebelisoa tse tsoetseng pele tsa ho itšeha tsa CNC tse nang le li-sensor tse nepahetseng haholo le litsamaiso tsa taolo tse khonang ho nepahala ha boemo ba micron.
Ho phaella moo, thepa ea 'mele ea thepa e tlameha ho nkoa nakong ea ho itšeha. Bakeng sa khalase ea optical, boima ba eona bo phahameng bo hloka mehato e khethehileng ea ho thibela ho phunyeha le ho thehoa ha litšila; bakeng sa polasetiki ea optical, tlhokomelo e tlameha ho nkoa ho qoba deformation ka lebaka la ho chesa haholo. Kahoo, khetho ea mekhoa ea ho itšeha le litlhophiso tsa parameter e tlameha ho ntlafatsoa ho latela lisebelisoa tse ikhethileng ho netefatsa liphetho tse nepahetseng.
3. Ho sila hamonate le ho bentša:
Ho sila hantle ke mohato oa bohlokoahali oa ho etsa lisebelisoa tsa optical. E akarelletsa ho sebelisa motsoako oa likaroloana tsa abrasive le metsi ho sila seipone disk, ka sepheo sa ho finyella lipakane tse peli tse ka sehloohong: (1) ho bapisa haufi-ufi radius e entsoeng; (2) ho felisa tšenyo e ka tlas’a lefatše. Ka ho laola ka mokhoa o nepahetseng boholo ba likaroloana le mahloriso a abrasive, tšenyo e ka tlas'a lefatše e ka fokotsoa ka katleho, kahoo e ntlafatsa ts'ebetso ea optical ea lense. Ho feta moo, ho bohlokoa ho etsa bonnete ba hore ho na le botenya bo nepahetseng ba setsi ho fana ka moeli o lekaneng bakeng sa polishing e latelang.
Ka mor'a ho sila hantle, lense e belisoa ho finyella sebaka se itseng sa ho kobeha, ho se tsitsa ha spherical, le ho qeta holimo ka ho sebelisa diski ea ho bentša. Nakong ea ho bentša, radius ea lense e lekanngoa khafetsa le ho laoloa ho sebelisoa lithempleite ho netefatsa ho latela litlhoko tsa moralo. Spherical irregularity e bolela tšitiso e kholo e lumelletsoeng ea leqhubu la spherical wavefront, e ka lekanngoang ka tekanyo ea ho kopana ha template kapa interferometry. Ho lemoha interferometer ho fana ka ho nepahala le ho nepahala ho holimo ha ho bapisoa le litekanyo tsa sampuli, tse itšetlehileng ka phihlelo ea molekoli 'me li ka hlahisa liphoso tsa likhakanyo. Ho feta moo, mefokolo ea lense e joalo ka mengoapo, likoti, le li-notch li tlameha ho fihlela maemo a boletsoeng ho netefatsa boleng le ts'ebetso ea sehlahisoa sa ho qetela.
4. Centering (Taolo ea Eccentricity kapa Equal Thickness Difference):
Ka mor'a ho bentša mahlakore ka bobeli a lense, ntlha ea lense e siloa hamonate holim'a lesela le khethehileng ho phetha mesebetsi e 'meli: (1) ho sila lense ho fihlela bophara ba eona ba ho qetela; (2) ho netefatsa hore axis ea optical e lumellana le mochine oa mochine. Mokhoa ona o hloka mekhoa e nepahetseng ea ho sila, litekanyo tse nepahetseng, le liphetoho. Ho tsamaisana lipakeng tsa lilepe tsa optical le mechanical axs ka kotloloho ho ama ts'ebetso ea lense ea mahlo, 'me ho kheloha leha e le hofe ho ka fella ka ho sotha litšoantšo kapa ho fokotsa tharollo. Ka hona, lisebelisoa tsa ho lekanya tse phahameng ka ho fetisisa, tse kang li-interferometers tsa laser le mekhoa ea ho ikamahanya le maemo, hangata e sebelisoa ho netefatsa hore ho na le ho lumellana ho phethahetseng pakeng tsa lilepe tsa optical le mechine.
Ka nako e le 'ngoe, ho sila sefofane kapa chamfer e khethehileng e tsitsitseng ka lense le eona ke karolo ea ts'ebetso ea centering. Li-chamfer tsena li ntlafatsa ho nepahala ha ho kenya, ho ntlafatsa matla a mochini, le ho thibela tšenyo nakong ea ts'ebeliso. Kahoo, centering ke ea bohlokoa bakeng sa ho netefatsa ts'ebetso ea optical le ts'ebetso e tsitsitseng ea nako e telele ea lense.
5. Kalafo ea ho Koala:
Lense e betliloeng e roaloa ho eketsa phetiso ea leseli le ho fokotsa ponahalo, ka hona e ntlafatsa boleng ba setšoantšo. Ho roala ke mohato oa bohlokoa oa ho etsa likarolo tsa optical, ho fetola litšoaneleho tsa ho hasana ha leseli ka ho beha filimi e le 'ngoe kapa tse ngata tse tšesaane holim'a lense. Lisebelisoa tse tloaelehileng tsa ho roala li kenyelletsa magnesium oxide le magnesium fluoride, tse tsejoang ka thepa ea tsona e ntle ea optical le botsitso ba lik'hemik'hale.
Ts'ebetso ea ho roala e hloka taolo e nepahetseng ea likarolo tsa thepa le botenya ba filimi ho netefatsa ts'ebetso e nepahetseng ea lera ka leng. Mohlala, ka lirafshoa tse ngata, botenya le motsoako oa thepa ea likarolo tse fapaneng li ka ntlafatsa haholo phetiso le ho fokotsa tahlehelo ea ponahatso. Ho feta moo, liphahlo li ka fana ka mesebetsi e khethehileng ea optical, joalo ka ho hanyetsa UV le anti-fogging, ho holisa mefuta ea ts'ebeliso ea lense le ts'ebetso. Ka hona, kalafo ea ho roala ha e bohlokoa feela bakeng sa ho ntlafatsa ts'ebetso ea optical empa hape e bohlokoa bakeng sa ho fihlela litlhoko tse fapaneng tsa ts'ebeliso.
