Ungasikhetha kanjani isilinganiso esifanele sokuhlanzeka kwamalensi wezimboni?

Ukukhetha inani elifanele lokuhlaselaIlensi yezimboniKudinga ukucubungula izinto eziningi, njengezidingo ezithile zohlelo lokusebenza, izidingo zokunemba zokulinganisa, isabelomali sezindleko, njll. Nazi iziphakamiso kanye nokucatshangelwa kokukhethwa:

1.Khomba izidingo zohlelo lokusebenza

Khomba izidingo ezithile zezicelo zezimboni zekhwalithi yesithombe nokunemba kokukalwa, bese unquma amazinga wekhwalithi yesithombe edingekayo ngokuya ngezidingo. Isibonelo, kwezinye izinhlelo zokusebenza ezidinga ukucaciswa okuphezulu nokunemba, kungahle kudingeke ukukhetha ilensi yezimboni ngenani eliphansi lokuhlanzeka.

2.-Zwayoaberrationtypes

Qonda umthelela wamanani entengo ahlukene we-Affertation ngekhwalithi yesithombe, kufaka phakathi ukuhlanekezela, ukusakazeka kwe-chromatic, ukusakazeka kwendawo, njll., Ukuze ukhethe ilensi yezimboni efanelekile yezicelo ezithile.

Izindaba zokuhlasela zihlukaniswe ikakhulu ekuhlaseleni kwe-radial kanye nokuhlaselwa kwe-tangentity. Izingozi ze-radial zivame ukuvezwa ngokuhlanekezela kwento onqenqemeni lwesithombe, kuyilapho ama-tangential afferrations ebangelwa amaphutha ama-angular phakathi kwelensi nendiza yokucabanga. Okokusebenzisa izicelo eziningi zezimboni, ama-radial abrrration cishe yinkinga evelele ngokwengeziwe.

3.Bheka ukucaciswa kwelensi

NiniUkukhetha ilensi, Kunconywa futhi ukubheka idatha yezinga le-ABRRATATE ekucacisweni kwayo, okuvame ukunikezwa njengephesenti le-Pixel. Ngezinhlelo zokusebenza ezidinga ukulinganiswa okunengqondo okuphezulu, kungahle kufaneleke ukukhetha ilensi ngesilinganiso esiphansi sokuhlanzeka.

4.Ukuqonda indlela yokuhlola

Abakhiqizi be-lens bavame ukuhlinzeka ngemininingwane noma izindlela zokuhlolwa kwe-Abrrration. Ukuqonda lezi zindlela zokuhlola kungasiza ukuhlola kahle ukusebenza kwe-lens.

5.Cabanga ngesabelomali sezindleko

Ngokuvamile, ama-lens wezimboni anamanani aphansi wokuhlasela azobiza kakhulu. Ngakho-ke, kuyadingeka ukuthi ucabangele isabelomali sezindleko ukuthola ukuthi ngabe ilensi esezingeni eliphakeme iyadingeka yini.

6.Cabanga Ngezici Zemvelo

Kuyadingeka futhi ukubheka izinto ezifana nezimo zokukhanyisa kanye nezinguquko zokushisa endaweni yokusebenza ukuze kuqinisekiswe ukuqina kanye nokwethenjwa kwelensi.

Ngaphezu kwezinga lokuhlanzeka, TheUkukhetha ilensiFuthi idinga ukubheka ukuthi amanye amapharamitha afana nesixazululo, inkambu yokubuka, ubude obugxile, njll. Hlangana nezidingo.

Imicabango yokugcina:

Uma unesifiso sokuthenga izinhlobo ezahlukahlukene zamalensi zokubhekwa, ukuskena, ama-drones, ekhaya elihlakaniphile, noma okunye ukusetshenziswa, sinakho okudingayo. Xhumana nathi namuhla ukuze ufunde kabanzi ngama-lens ethu nezinye izesekeli.
