1.base umgangatho wezinto eziphathekayo.
Umgangatho we-substrate unquma ukuqina kwelensi kunye nokuthembeka kwengubo.I-substrate elungileyo ecacileyo kwaye eqaqambileyo, ixesha elide lokusebenzisa kwaye akukho lula ukutyheli;Kwaye ezinye iilensi azithathi xesha lide ukuba zijike zibe tyheli, kwaye nokwaleka kuyawa.I-lens elungileyo ngaphandle komkrwelo, umkrwelo, iinwele, i-pitting, i-lens oblique ekubonweni kokukhanya, ukugqiba okuphezulu.Akukho mabala, amatye, imivimbo, amaqamza kunye nokuqhekeka ngaphakathi kwelensi, kwaye ukukhanya kuqaqambile.
2.Ibakala lelensi.
Iilensi eziveliswe ngobuninzi zohlulwe ngokwamabakala ahlukeneyo ngenxa yomahluko kumgangatho wangaphakathi, kwaye amaxabiso eemveliso eziphezulu nezingaphantsi ahluka kakhulu.
3.Isalathiso seRefractive.
I-index ye-refractive ephezulu, i-lens encinci, kunye nexabiso eliphezulu.
I-4.i-coating kunye ne-anti-ultraviolet unyango.
Iphepha le-resin linokuba lukhuni (ukuchasana nokukrala), ukuchasana-reflection, i-anti-static, i-dustproof, ukusetyenzwa kwamanzi okugquma amanzi amaninzi njengeshumi elinesibini, ukusetyenzwa kweengubo ezahlukeneyo kunendima eyahlukileyo, ukuba kunciphisa inkqubo yokugubungela, umgangatho we-lens. iya kuthotywa kakhulu.Ngokufanayo, ukuba iilensi aziyithinteli i-uv njengoko iilensi ze-uv zinxiba, ngoko ke kuyingozi kakhulu emehlweni.
5. Uphawu lwelensi.
Ukwahluka kwebrendi kukhokelela kumahluko kumgangatho kunye nexabiso.Umgangatho welensi ubonakaliswa ngokuthe ngqo kwi-brand lens.Iilensi zohlobo oludumileyo zikumgangatho olungileyo kwaye zizinzile.
6. Vavanya ukungafihli kunye nokufana kwe-optical ye-lens.
Bamba ilensi 30 cm kude neliso kwaye ujonge imbonakalo ekude ngelensi.Ukuba imbonakalo yelizwe icacile kwaye ingenakuguqulwa, kwaye akukho ndawo yokutsiba xa uhambisa ilensi kancinane, ukungafihli kunye nokufana kokubona kwelensi kulungile.
7. Qinisekisa i-axial direction ye-astigmatism lens.
Kwiphepha elingenanto ukuzoba umnqamlezo ifolokhwe perpendicular, beka ilens kwi spider jikelisa umzobo ngaphezu 30 centimeters, lens ebonakalayo ukuhambisa umnqamlezo ifolokhwe umnqamlezo, ilens ngaphakathi kwaye xa uqhagamshelwe imizobo umnqamlezo, imizobo wayeqinisekile cross, apho ikholamu i-axis yelensi kunye nomgca othe ngqo, emva koko iilensi zazihamba ngokuphindaphindiweyo kumgca othe ngqo;Qaphela ukuba ngowuphi umgca owahluka kakhulu kumgca ongaphandle kwelensi xa ushukuma, kwaye lo mgca licala le-axis ye-scatterlight.
8. Vavanya i-optical center displacement.
Zoba umnqamlezo omkhulu kwisiqwenga sephepha elimhlophe kumgca omncinci, ocacileyo, othe ngqo.Bamba i-lens phakathi kwamehlo kunye nomnqamlezo, jonga ubume bomnqamlezo kwisibuko ngeliso elinye, ukuba ngaphakathi nangaphandle kwesibuko asikho kumgca, unokuhambisa i-lens, ukwenzela ukuba ngaphakathi kwe-lens umphandle wesipili umgca wokunqumla.Sebenzisa ibrashi okanye ipeni lomthombo ukuze ubeke inqaku elincinci kwiziko le-lens, eliziko le-optical.Emva kokukhomba amaziko okukhanya kuzo zombini iilensi, jonga kwaye uqhathanise ukuba ngaba amaziko optical amabini ane-symmetrical, kwaye ulinganise umgama phakathi kwamaziko amabini kunye nomlawuli omncinci ukubona ukuba umgama phakathi kwamaziko amabini uhambelana nomgama omiselweyo kumfundi. .Ukuba umnqamlezo kwi-lens ugobile, kubonisa ukuba kukho uxinzelelo lwangaphakathi okanye ukuxinana kwe-optical engalinganiyo ye-lens.
9.nxiba imvakalelo.
Nxiba ngaphandle kokuziva, isiyezi, ukudumba kwamehlo, izinto zokujonga azikho mfiliba, azikhubazekanga.Xa uthenga, bamba iindondo ngesandla kwaye ujonge izinto ezikude ngeliso elinye kwilensi.Gcoba i-lens phezulu naphantsi.Inkohliso yokuhamba kwezinto ezikude akufanele yenzeke.
10. Ukhuseleko.
Iilensi ezikumgangatho ophezulu zinokuvala imitha ye-uv ngokufanelekileyo kwaye zibonelele ngokhuseleko olusebenzayo lwe-uv kulowo uyinxibileyo.
