Yiziphi intuthuko yangaphakathi kanye nentuthuko yangaphandle?
I-Outer Progressives
Ilensi yangaphandle eqhubekayo ibizwa nangokuthi ilensi eqhubekayo yomklamo wangaphambili, okungukuthi indawo yegradient yamandla ibekwe endaweni engaphambili yelensi, buqamama namehlo.
I-Inner Progressives
I-Inner progressive yaziwa nangokuthi i-back surface design lens eqhubekayo, lolu hlobo lwamalensi aqhubekayo lubhekisela ekusetshenzisweni kobuchwepheshe bobuso befomu yamahhala kanye nemishini yokucubungula i-lathe ukubeka idizayini ye-degree gradient (indawo esebenzayo) endaweni engemuva, eseduze kakhulu namehlo.
Umehluko wokukhiqiza phakathi kwenqubekela phambili yangaphakathi kanye nenqubekela phambili yangaphandle
Oisisu esiqhubekayoama-lens akhiqizwa kusetshenziswa inhlanganisela yezindlela ezimbili zokucubungula.
1. Ukucubungula kokuqala
I-ADD kanye nobude bephaseji yendawo yangaphandle yakhelwe endaweni engaphambili yesikhunta ilensi, futhi isikhunta esingemuva kwelensi asinalo ushintsho ekujikeni kwe-photometric.I-lens substrate ene-ADD ikhiqizwa isikhunta ezimbili kusetshenziswa umugqa wokuhlanganisa, onikezelwe kumalensi aqhubekayo.I-substrate, hhayi ukusetshenziswa ekukhiqizeni ezinye izinhlobo zamalensi.Ngokuvamile ukukhiqizwa kwama-substrates anjalo kudinga ukuhambisana ne-ADD ngayinye, ngakho-ke i-inventory yokugcina yama-substrates inkulu kakhulu.
2. Ukucubungula okwesibili
Kusuka esitokisini samalensi akhiqizwe ukucubungula kokuqala, thola amalensi e-UC ane-ADD edingekayo, futhi uwafake endaweni engemuva yelensi ukuze uzuze amandla akude.Ngemva kwalezi zinyathelo ezimbili zokucubungula, ipheya yamalensi aqhubekayo ayaqedwa.
Ukuqhubekela phambili kwangaphakathi, indawo yayo ye-gradient itholakala endaweni engaphakathi yelensi, futhi isikhungo sayo sitholakala endaweni engaphakathi yelensi.Indawo yayo yangaphandle ithatha umklamo ofanayo oyindilinga noma oyi-aspheric njengamalensi ombono owodwa ajwayelekile.
Ihlukile kubuchwepheshe bokucubungula bendabuko, ilensi yangaphakathi yefomu yamahhala eqhubekayo ingaklanywa ngokuya ngohlelo lwekhompiyutha, futhi yamukele ukwakheka okuhlanganisiwe kokubumba.Ngosizo lobuchwepheshe bokucubungula "i-soft polishing", inqubo yokuguqula idijithali yekhwalithi ephezulu yendawo yangemuva ye-lens ingagcinwa ngokuphelele.Umklamo wangempela oqhubekayo.
