E 'ngoe ea lipotso tseo batho ba bangata ba li utloang ha ba kenya lilense tsa bona ke, "U hloka index efe ea refractive?"Ke lumela hore batho ba bangata ha ba utloisise lentsoe lena la litsebi, ha re ithuteng ka lona kajeno!
Batho ba bangata sechabeng sa kajeno ba lumela hore likhalase tse theko e boima haholo li molemo!Litsebi tse ngata tsa mahlo, li tšoara kelello ena ea bareki, hangata li sebelisa refractive index e le ntlha ea ho rekisa ho eketsa theko ea likhalase e le ho fumana melemo e phahameng ea moruo.Ke hore, ho phahama ha index ea refractive, lense e fokolang, 'me theko e theko e boima haholo!
Monyetla o ka sehloohong oa lilense tse phahameng-refractive ke bosesaane ba tsona.Bareki ba khetho ea lilense, ba tlameha ho khetha ho ea ka likhato tse fapaneng tsa mahlo ho lumellana le tsa bona, ts'ebetso e babatsehang ea lense, ho lelekisa sefofu sa index e phahameng ea refractive ha e lakatsehe, e loketseng ke ea bohlokoa ka ho fetisisa!
Lilense tse ntle tsa optical li lokela ho bua ka lilense tse nang le thepa e ntle ea optical, e bonts'itsoeng ka phetisetso e phahameng, ho hlaka ho hoholo, ho hasana ho nyane, ho hanyetsa ho apara hantle, ho roala ka mokhoa o motle le ts'ebetso e ntle ea ts'ireletso.
Hangata index ea refractive ea lilense e kenyelletsa 1.49, 1.56, 1.61, 1.67, 1.74, 1.8, 1.9.
Ho ea ka pono ea setsebi ho khetha index ea refractive ka kakaretso ho latela ho nahanoa ka botlalo:
1. Tekanyo ea myopia.
Myopia e ka aroloa ka myopia e bonolo (ka har'a likhato tse 3.00), myopia e itekanetseng (pakeng tsa 3.00 le 6.00 degrees), le myopia e phahameng (ka holimo ho likhato tse 6.00).
Ka kakaretso HO BUA LESEDI LE MYOPIA e itekanetseng (dikerii tse 400 ka tlase ho) KHETHA REFRACTIVE INDEX KE 1.56 OK, (300 degrees to 600 degrees) KA 1.56 KAPA 1.61 MEFUTA ena e MEBEDI ya kgetho ya REFRACTIVE index, 600 degrees ka hodimo e ka nahana ka 1.611 kapa 1. lense.
Ha index ea refractive e phahame, ho ba le refraction e eketsehileng ka mor'a hore leseli le fete ka lense, 'me lense e le tšesaane.Leha ho le joalo, ha index ea refractive e phahame, ho na le taba e tebileng haholoanyane ea ho hasana, kahoo lense e phahameng ea refractive index e na le palo e tlaase ea Abbe.Ka mantsoe a mang, ha index ea refractive e phahame, lense e tšesaane, empa ha u sheba lintho, ho hlaka ha 'mala ha ho na maruo ha ho bapisoa le 1.56 refractive index.Se boleloang mona ke phapang e fokolang feela papisong e lekanyelitsoeng.Ka theknoloji ea hajoale, lense e nang le index e phahameng ea refractive e boetse e ntle haholo ponong.Lilense tse phahameng tsa refractive index hangata li sebelisoa feela bakeng sa likhato tse likete.
2. Litlhoko tsa sehlooho.
Khetho ea index ea refractive ho ea ka tekanyo ea myopia ha e felle ka ho feletseng, empa e tlameha ho kopanngoa le khetho ea foreimi le boemo ba sebele ba leihlo ho etsa qeto.
Hona joale myopic tekanyo e ka kakaretso phahameng, ho tse hlano ho isa ho tse tšeletseng myopia baidu, tlaase refractive index ea lense e tla ba teteaneng, boima ba 'mele e tla ba tse seng kae tse khōloanyane, ka nako ena, haeba ho hahamalla tekanyo e ntle e phahameng, re fana ka maikutlo a ho feta 1,61 refractive index, ho feta moo ha u khetha foreimi ea setšoantšo ho qoba mofuta o moholo oa lebokose, ka kakaretso, likhalase tsa likhalase tsa botle le matšeliso li batla li le ntle.
Qeto: KHETHO EA LINTHO TSA refractive e lokela ho ipapisa le keletso ea ngaka ea mahlo ea setsebi, ho ea ka tekanyo ea myopia, boholo ba foreimi, litlhoko tsa botle, matšeliso a pono, tšebeliso ea chelete le lintlha tse ling tse pharaletseng, tse loketseng ke tsa bohlokoa ka ho fetisisa.
