Iinkcukacha zeMveliso

1.50 CR-39

Iithegi zeMveliso

Iilensi ezicacileyo zezona zisetyenziswa ngokuqhelekileyo kwiimboniselo zokulungisa.Ukunikezela ukucaca komgangatho ophezulu, ukunciphisa ukukhanya kokukhanya, ukuphucula ukuchasana kunye nokuphucula ukusebenza okubonakalayo, umsebenzi wabo kukubonelela ngombono ocacileyo we-crystal ngokukhululekile.Iilensi ezicacileyo zifanelekile kwabo banxiba iiglasi imini yonke.Zikwalungile kwabo bathanda inkangeleko yokuba ukunxiba iindondo kubanika, nokuba amehlo abo abona kakuhle.Ngelizwi, iilensi ezicacileyo zilungile kumntu wonke
I-Hopesun inikeza enye yezona zinto zikhethiweyo ezikhethiweyo zeelensi ezicacileyo kuzo zonke izinto ezivela kwi-1.50 index ukuya kwi-1.74 index.Zonke iilensi zenziwe ngezona zinto zisemgangathweni emhlabeni, njenge-CR-39 evela kwi-PPG, uthotho lwe-MR oluvela kwiMitsui Chemicals ukuqinisekisa ukucaca kwelensi, ukhuseleko, ukuqina.I-Hopesun isitokhwe uluhlu olukhulu kunye nesixa seelensi ezicacileyo ezigqityiweyo kumbono omnye, i-bifocal kunye nenkqubela phambili.

Ukuba uwuxabisile umgangatho, ukusebenza kunye nokutsha ufike kwindawo elungileyo.

I-CR39(1.50 isalathiso se-refractive):I-CR39 ibonakaliswe ngenani eliphezulu le-Abbe, ukucaca okuphezulu, ukuxhathisa okunamandla (ngaphandle kokugquma), ukuxinana okuphantsi (malunga nesiqingatha esingaphantsi kwe-lens yeglasi), ukusebenza kakuhle kokudaya, ukuxhathisa i-solvent, ukuxhathisa imichiza kunye nokuxhathisa ukushisa.Kwaye ngenxa yokuba inkqubo yokuvelisa ikhulile, indleko ephantsi, kude kube ngoku isesinye sezinto eziphambili kwishishini le-lens.Nangona kunjalo, i-CR39 i-brittle encinci kunezinye izinto malunga nokuxhathisa impembelelo kunye namandla okuqina, ngoko ke ayifanelekanga kwiiglasi ezingenamsinga (iilensi zikholisa ukuphuka xa zombiwa), kwaye inesalathiso esisezantsi sokukhenkceza, okwenza iilensi zibe ngqindilili kwiqondo eliphezulu.

1.56 Isalathiso esizinyibilikisayo:Isixhobo ekrwada ngokuqhelekileyo NK55, nto leyo edla ngokubizwa ngokuba acrylic.Ixabiso liphantsi kwaye izinga lokusetyenziswa liphezulu, kodwa ingqiqo yokukhanya ibuthathaka.I-lens i-brittle, kwaye kulula ukuphuka xa ubhobhoza isakhelo.

1.59 PC imathiriyeli:Izinto zePC yiPolycarbonate, eyiplastiki ye-thermoplastic ene-refractive index ye-1.59 kunye nokumelana nempembelelo enamandla.Ingasetyenziswa njengeeglasi zembumbulu kunye nezigcina-ntloko kwindawo yomkhosi.Ingasetyenziselwa kwiiglasi ngaphandle kokukhathazeka malunga nokuphulwa kweelensi.Ifanelekile kwiiglasi ezingenamsinga.Kwaye isalathisi se-refractive siphezulu kune-CR39, i-lens ingenziwa ibe yincinci.Kodwa njengesixhobo se-thermoplastic, ukusebenza kwayo kunye nokuchasana kweekhemikhali akulunganga, indawo engagqunywanga nayo kulula ukuyikrwempa, ukumelana nokunxiba.Ukongeza, inombolo yayo ye-Abbe yi-30, ehluke ngama-28 kwi-CR39.

Izinto ze-MR (1.60MR-8, 1.67MR-7, 1.74MR-174):I-MR™ luluhlu lwezixhobo zeresin ephakathi kunye neziphezulu ezibonisa irefractive eziphuhliswe yiMitsui Chemical Company yaseJapan.Ngaphandle kwe-MR174, lonke uchungechunge lwenziwe ngezinto eziphathekayo ze-polyurethane (i-MR174 yimpahla yesulfure enendandatho enokumelana nokusasazeka okungcono).Nangona ukuchasana kwempembelelo kungalunganga njengePC kunye ne-Trivex, kunezibonelelo ezicacileyo ngaphezulu kwe-CR39.Ukongeza, inani le-abbe yolu chungechunge lwezixhobo liphakathi, ukumelana nobushushu, ukuxhathisa kwemozulu kunye nokuchasana kweekhemikhali kulungile, ngoko kunomsebenzi obanzi obanzi.
