Njengoko sonke sisazi,ilensi ye-telecentricluhlobo lwelensi yemizi-mveliso ekhethekileyo eyenzelwe ukusetyenziswa kombono womatshini. Akukho mgaqo umiselweyo wokukhetha kwayo, kwaye ixhomekeke kakhulu ekubeni ingahlangabezana neemfuno zokudubula.
Njani Ukukhetha ilensi ye-telecentric? Zeziphi izinto ekufuneka ziqwalaselwe?
Ngokubanzi, ngaphambi kokukhetha ilensi ye-telecentric, kufuneka kuqwalaselwe ezi zinto zilandelayo:
Ubude befocal kunye nommandla wombono
Kuyimfuneko ukukhetha ubude obufanelekileyo befocal kunye ne-Angle yentsimi ngokweemfuno zokusetyenziswa kunye nobukhulu kunye neempawu zethagethi. Ubude obude befocal bunokubonelela ngesisombululo esiphezulu kunye neenkcukacha, ngelixa ii-engile ezinkulu zentsimi zinokugubungela indawo ebanzi.
Ubude befocal lens ye-telecentric budla ngokuba phakathi kwe-17mm kunye ne-135mm, kwaye ukhetho lobude befocal luxhomekeke kakhulu kwinto ofuna ukuyifota. Abafoti be-landscape banokufuna ubude befocal obubanzi, ngelixa abafoti bezakhiwo banokufuna ngaphezulu kwe-35mm.
Ukukhetha ubude befocal kwiifoto ezahlukeneyo
Umgangatho wokukhanya
Khethailensi ye-telecentrickunye noyilo oluphezulu lwe-optical kunye nenkqubo yokuvelisa ukuqinisekisa ukucaca nokuchaneka komfanekiso ojongwayo. Umgangatho we-optical uquka izinto zelensi, iteknoloji yokugquma, isalathisi sokuqaqamba kwezixhobo zelensi njalo njalo.
Ubungakanani bembobo
Ubungakanani be-Aperture buchaphazela ukusebenza kwelensi kwiindawo ezikhanyayo kancinci kunye nolawulo lobunzulu bemvelaphi. Ngokubanzi, i-aperture ye-f/2.8 okanye enkulu ifanelekile ukusetyenziswa kwiindawo ezimnyama, ngelixa i-aperture ye-f/4 okanye encinci ifanelekile ukusetyenziswa kwiindawo ezikhanyayo.
Isiphumo sobukhulu bomngxuma ekudubuleni
Uyilo kunye nesakhiwo
Cinga ngoyilo kunye neempawu zesakhiwo seilensi ye-telecentric, njengenkqubo yohlengahlengiso lwecandelo elijolise ngqo, inkqubo yohlengahlengiso olujolise ngqo, ukugquma ilensi kunye neminye imisebenzi. Uyilo kunye nolwakhiwo lwale miba luya kuchaphazela ngokuthe ngqo ukusebenziseka lula kunye nefuthe lokujonga lensi ye-telecentric.
Uhlahlo-lwabiwo mali kunye neemfuno zokwenyani
Xa ukhetha ilensi ye-telecentric, kufuneka ulinganise izinto ezahlukeneyo ngokwebhajethi yakho kunye neemfuno zokujonga zokwenyani. Ezinye iilensi ze-telecentric zingabiza kakhulu, kodwa zinokubonelela ngeziphumo zokubukela ezingcono; Kukho iimveliso ezingabizi kakhulu ngokwentsebenzo kwaye ixabiso linokuba lukhetho olufanelekileyo. Ngokuqhelekileyo kuyacetyiswa ukuba ukhethe iimveliso ezingabizi kakhulu phantsi kwengcamango yokuhlangabezana neemfuno.
Uphawu kunye nenkonzo
Iimpawu ezahlukeneyo zinokuchaphazela ukusebenza kunye nomgangatho welensi. Kwiimeko eziqhelekileyo, ukhetho lweempawu ezaziwayo kunye nodumo oluhleilensi ye-telecentriciimveliso zinokuqinisekisa umgangatho wemveliso kunye nenkonzo yasemva kokuthengisa. Ezinye iimpawu zinokubonelela ngeziqinisekiso zexesha elide okanye zibe neendawo zokulungisa ezigunyazisiweyo ngakumbi.
Iingcinga Zokugqibela:
Ngokusebenzisana neengcali eChuangAn, zombini uyilo kunye nokuveliswa kulawulwa ziinjineli ezinobuchule obuphezulu. Njengenxalenye yenkqubo yokuthenga, ummeli wenkampani unokuchaza ngokweenkcukacha ulwazi oluthile malunga nohlobo lwelensi ofuna ukuyithenga. Uthotho lweemveliso zelensi zikaChuangAn zisetyenziswa kwiintlobo ngeentlobo zezicelo, ukusuka ekujongeni, ukuskena, iidrone, iimoto ukuya kumakhaya akrelekrele, njl. IChuangAn ineentlobo ngeentlobo zeelensi ezigqityiweyo, ezinokutshintshwa okanye zenziwe ngokwezifiso ngokweemfuno zakho. Qhagamshelana nathi ngokukhawuleza.
