Uzivavanya njani iiLensi zokuBono ngoomatshini? Ziziphi Ezi Ndlela?

Ukuze kuqinisekiswe ukuba i-lens inokubonelela ngemifanekiso esemgangathweni ophezulu kunye nokusebenza okuthembekileyo kwiimeko ezithile zesicelo, kuyimfuneko ukuqhuba ukuvavanya okufanelekileyo kwi-lens. Ke, zeziphi iindlela zovavanyoiilensi zombono womatshini? Kweli nqaku, siza kufunda indlela yokuvavanya iilensi zombono womatshini.

Uzivandlakanya njani iilensi zombono womatshini

Zeziphi iindlela zokuvavanya iilensi zokujonga koomatshini?

Ukuvavanywa kweelensi zombono womatshini kufuneka kuthathelwe ingqalelo iinkalo ezininzi zeeparamitha zokusebenza kunye neempawu, kwaye kufuneka ziqhutywe phantsi kokusebenza kwezixhobo ezikhethekileyo kunye neengcali zokuqinisekisa ukuba iziphumo zovavanyo zichanekile kwaye ziyasebenza.

Ezi zilandelayo zezona ndlela ziphambili zovavanyo:

1.Indawo yovavanyo lokujonga

Indawo yokujonga ilensi imisela ubungakanani bendawo enokuthi ibonwe yinkqubo yamehlo, kwaye ngokuqhelekileyo inokuvavanywa ngokulinganisa i-diameter yomfanekiso owenziwe yi-lens kubude obukhethekileyo bojoliso.

2.Uvavanyo lokuguqula

Ukugqwethwa kubhekiselele kuguquko olwenzeka xa ilensi iprojekthi into yokwenyani kwinqwelomoya yomfanekiso. Kukho iintlobo ezimbini eziphambili: ukuguqulwa komgqomo kunye nokuphazamiseka kwepinki.

Uvavanyo lunokwenziwa ngokuthatha imifanekiso yokulinganisa kwaye emva koko kwenziwe ulungiso lwejometri kunye nohlalutyo lokuphazamiseka. Ungasebenzisa kwakhona ikhadi lokuvavanya isisombululo esiqhelekileyo, njengekhadi lovavanyo kunye negridi eqhelekileyo, ukujonga ukuba imigca emiphethweni igobile.

3.Uvavanyo lwesigqibo

Isisombululo selensi simisela ingcaciso ecacileyo yomfanekiso. Ke ngoko, isisombululo sesona sizathu sibalulekileyo sovavanyo lwelensi. Ngokuqhelekileyo kuvavanywa kusetyenziswa ikhadi lokuvavanya isisombululo esiqhelekileyo kunye nesofthiwe yohlalutyo ehambelanayo. Ngokuqhelekileyo, isisombululo se-lens sichatshazelwa zizinto ezifana nobukhulu bokuvula kunye nobude bokugxila.

4.BUvavanyo lobude be-ack

Ubude bokujongwa ngasemva ngumgama ukusuka kwinqwelomoya yomfanekiso ukuya ngasemva kwelensi. Kwilensi egxininisiweyo yobude obugxininisiweyo, ubude bendawo yangasemva buzinzile, ngelixa ilensi yokusondeza, ubude bengqwalasela yangasemva buyatshintsha njengoko ubude bokugxila buguquka.

5.Uvavanyo lobuthathaka

Uvakalelo lunokuvavanywa ngokulinganisa isibonakaliso esiphezulu semveliso enokuthi i-lens ivelise phantsi kweemeko ezithile zokukhanyisa.

6.Uvavanyo lweChromatic aberration

I-Chromatic aberration ibhekisa kwingxaki ebangelwa kukungangqinelani kweendawo ekugxilwe kuzo zemibala eyahlukeneyo yokukhanya xa ilensi isenza umfanekiso. I-Chromatic aberration inokuvavanywa ngokujonga ukuba imiphetho yombala emfanekisweni icacile, okanye ngokusebenzisa itshathi yokuvavanya umbala okhethekileyo.

7.Uvavanyo lokuthelekisa

Umahluko ngumahluko ekukhanyeni phakathi kwawona manqaku aqaqambileyo namnyama kumfanekiso oveliswe ilensi. Inokuvavanywa ngokuthelekisa isiziba esimhlophe kwisiqwenga esimnyama okanye ngokusebenzisa itshathi yovavanyo olukhethekileyo (njengetshathi yeStupel).

8.Uvavanyo lweVignetting

I-Vignetting yinto yokuba ukuqaqamba komphetho womfanekiso kusezantsi kunoko kumbindi ngenxa yokucuthwa kwesakhiwo selensi. Uvavanyo lweVignetting luqhele ukulinganiswa kusetyenziswa imvelaphi emhlophe efanayo ukuthelekisa umahluko wokuqaqamba phakathi kombindi kunye nokuphela komfanekiso.

9.Uvavanyo lokubonisa i-Anti-Fresnel

I-Fresnel reflection ibhekisa kwisenzeko sokubonakaliswa kokukhanya ngokuyinxenye xa isasaza phakathi kwemidiya eyahlukeneyo. Ngokuqhelekileyo, umthombo wokukhanya usetyenziselwa ukukhanyisa i-lens kunye nokujonga umboniso wokuvavanya ukukwazi ukuchasana nokubonakala kwelensi.

10.Uvavanyo lokudlulisela

Ukudluliselwa, oko kukuthi, ukuhanjiswa kwelensi kwi-fluorescence, kunokulinganiswa kusetyenziswa izixhobo ezifana ne-spectrophotometer.

Iingcamango zokugqibela:

UChuangAn uye waqhuba uyilo lokuqala kunye nokuveliswa kweiilensi zombono womatshini, ezisetyenziswa kuzo zonke iinkalo zeenkqubo zombono womatshini. Ukuba unomdla okanye uneemfuno zeelensi zombono womatshini, nceda uqhagamshelane nathi ngokukhawuleza.
