Wuma kuziwa ekukhetheni izibuko zamehlo, sivame ukubhekana nesinqumo esibalulekile: amalensi ayindilinga noma amalensi aspherical?Nakuba amalensi ayindilinga bekulokhu okuthandwa kakhulu, amalensi aspherical aqhamuke njengenye indlela entsha enohlu lwezinzuzo.Lesi sihloko sizohlola umehluko phakathi kwamalensi ayindilinga nawe-aspherical, futhi sixoxe ngezinzuzo zamalensi aspherical.
Incazelo kanye Nomehluko:
Umehluko omkhulu phakathi kwamalensi ayindilinga nawe-aspherical usekumeni kwawo kanye nokugoba kwawo.Amalensi ayindilinga ane-curvature efanayo kuyo yonke ilensi, kuyilapho amalensi aspherical anamagophe angavamile angenziwa ngezifiso ngokusekelwe esimweni somuntu ngamunye.
Inzuzo 1: Ukubukeka Kwemvelo Okungaphezulu
Enye yezinzuzo ezibalulekile ze-asphericalamalensi ukuthi anikeza ukubukeka kwemvelo okwengeziwe.Uma kuqhathaniswa namalensi ayindilinga, ukugoba kwamalensi aspherical kungakwazi ukuzivumelanisa kangcono nokugoba kweso, kunciphise ukuhlanekezela kokuma kwelensi.Lokhu kusho ukuthi abagqoki bamalensi aspherical bangakwazi ukubona izithombe ngokucacile nangokweqiniso, ngaphandle kokukhathazeka ngokuthi ukuvela kwama-lens shapes kubonakala kwabanye.
Inzuzo 2: Inkambu Ebanzi Yokubuka
Ngaphezu kwenzuzo yobuhle, ama-lens aspherical abuye anikeze insimu yokubuka ebanzi.Amalensi aspherical aklanyelwe ukucabangela indawo yomfundi kanye nokugoba kwe-retina, ehlisa ukuhlanekezela okubangelwa ukukhanyela ukukhanya futhi avumele ukuqagela kwezinto ezikwilensi ukuthi kusondele ekubukekeni kwazo kwasekuqaleni.Lokhu akuhlinzeki kuphela abagqokile isipiliyoni esicacile esibonakalayo kodwa futhi kusiza ekudambiseni ukukhathala kwamehlo.
Inzuzo 3: Ilensi ekhanyayo
Amalensi aspherical ngokuvamile alula kunamalensi ayindilinga anencwadi kadokotela efanayo.Lokhu kungenxa yokuthi amalensi aspherical enziwa ngokwezifiso ngokusekelwe ezidingweni zomuntu ngamunye, ukugwema ukumosha izinto ezingadingekile.Ngenxa yalokho, abagqoki bangajabulela isipiliyoni sokugqoka ngokunethezeka ngenkathi behlisa umthwalo ebunzini nasekhaleni lebhuloho, behlisa ingcindezi.
Ukukhetha izibuko zamehlo ezifanele kuyisici esibalulekile sokunakekelwa komuntu siqu.Amalensi aspherical anikeza ukukhetha okusha kwabagqoka izibuko zamehlo ngokunikeza ukubukeka kwemvelo okwengeziwe, indawo yokubuka ebanzi, namalensi alula.Uma udinga ukuthenga izibuko zamehlo ezintsha, cabanga amalensi aspherical ukuze uthole umuzwa obonakalayo onethezeke futhi ocace kakhudlwana.
