Iyini i-lens yomshini wokubona?
A umshini wokubona lensiyingxenye ebalulekile ohlelweni lokubona komshini, oluvame ukusetshenziswa ekukhiqizeni, ezamarobhothi, nasezinhlelweni zokuhlola izimboni.Ilensi isiza ukuthwebula izithombe, ihumushe amaza okukhanya abe yifomethi yedijithali uhlelo olungayiqonda futhi luyicubungule.Ikhwalithi nezici zamalensi zingathinta kakhulu ikhono lesistimu lokuhlonza ngokunembile, ukulinganisa, noma ukuhlola izinto.
Ziyini izinhlobo zamalensi ombono womshini?
Ezinye izinhlobo ezijwayelekile zamalensi ombono womshini zihlanganisa:
1.Amalensi obude obugxilile obugxilile: Lawa ma-lens anobude obugxilile obugxilile futhi ahlinzeka ngokukhuliswa okungaguquki kokuthwebula izithombe zezinto ebangeni elithile ukusuka kumalensi.Zifanele izinhlelo zokusebenza lapho ibanga lokusebenza nosayizi wento kuhlala njalo.
2.Amalensi wokusondeza:Amalensi okusondeza anikeza ubude bokugxila obulungisekayo, okuvumela abasebenzisi ukuthi bashintshe inkambu yokubuka nokukhulisa njengoba kudingeka.Banikeza ukuguquguquka ekuthwebuleni izithombe zezinto emabangeni ahlukahlukene.
3.Amalensi kagesi:Amalensi e-Telecentric aklanyelwe ukukhiqiza imisebe yokukhanya ehambisanayo, okusho ukuthi imisebe eyinhloko i-perpendicular inzwa yesithombe.Lesi sici siphumela esilinganisweni esinembile nesiguquguqukayo sobukhulu bento, okubenza bafanelekele izinhlelo zokusebenza zokulinganisa ukunemba.
4.Amalensi ane-engeli ebanzi: Amalensi ane-engeli ebanzi anobude bokugxila obufushane kanye nenkundla yokubuka ebanzi, okuwenza abe usizo ezinhlelweni ezidinga ukuthwebula izithombe zezindawo ezinkulu noma izigcawu.
Lapho ukhetha ilensi yombono womshini, izinto okufanele zicatshangelwe zifaka phakathi ibanga lokusebenza olifunayo, indawo yokubuka, ukulungiswa, ikhwalithi yesithombe, ukuhambisana kokukhwezwa kwelensi, kanye nezimfuneko ezithile zohlelo lokusebenza.
Yiziphi izici ze-lens yombono womshinis?
Izici zamalensi omshini zingahluka kuye ngomkhiqizi welensi ethile kanye nemodeli.Kodwa-ke, ezinye izici ezijwayelekile zamalensi ombono womshini zifaka:
1.I-High-resolution Optics:Amalensi omshini aklanyelwe ukuhlinzeka ngezithombe ezicacile nezicijile, ngokuvamile ezifanelana namandla okulungiswa kwamakhamera anokucaca okuphezulu.
2.Ukuhlanekezela okuphansi: Amalensi anokuphazamiseka okuphansi aqinisekisa ukuthi isithombe esishuthiwe sinembile futhi asihlanekezelwe, ikakhulukazi ezinhlelweni zokusebenza ezidinga izilinganiso ezinembile noma ukuhlolwa.
3.Ibanga elibanzi le-spectral:Amanye amalensi omshini aklanyelwe ukusebenza ngamaza ahlukene okukhanya, okuvumela izinhlelo ezisebenzisa ukukhanya okubonakalayo, ukukhanya kwe-ultraviolet (UV), ukukhanya kwe-infrared (IR), noma ukuthwebula izithombe nge-multispectral.
4.Ukuguquguquka nokuguquguquka: Amalensi athile, njengamalensi okusondeza, anikeza ubude bokugxila obulungisekayo kanye nenkundla yokubuka, enikeza ikhono lokuthwebula izithombe ngokukhuliswa okuhlukahlukene namabanga ezinto.
5.Telecentricity: Amalensi e-telecentric akhiqiza imisebe yokukhanya ehambisanayo, okuholela ekukhuliseni okungaguquguquki kanye nesilinganiso esinembile sobukhulu bento, kungakhathaliseki ibanga lento.
6.Ukulungiswa kokugxila: Amalensi okubona omshini ngokuvamile ahlinzeka ngokulungiswa kokugxilisa okwenziwa ngesandla noma kwezimoto, okuvumela abasebenzisi ukuthi bathuthukise ukucija kwesithombe kumabanga ezinto ezihlukene.
7.Idizayini eqinile nengasindi: Amalensi omshini ngokuvamile aklanyelwe ukuthi ahlangane futhi angasindi, awenze afanelekele ukuhlanganiswa ezinhlelweni zombono futhi kuncishiswe ukunyathelisa kwawo wonke.
8.Mount ukuhambisana: Amalensi okubona omshini ayatholakala ngokufakwa okuhlukahlukene kwamalensi (okufana ne-C-mount, F-mount, M42, njll.), okuqinisekisa ukuhambisana nezinhlobonhlobo zamakhamera noma izixhumanisi.
9.Ukuqina kwemvelo: Amanye amalensi omshini aklanyelwe ukumelana nezindawo zezimboni ezinokhahlo, anezici ezifana nezindlu eziqinile, ukuvikela uthuli, nokumelana nokudlidliza noma ukuhluka kwezinga lokushisa.
10. Ukusebenza kahle kwezindleko: Amalensi okubona omshini ngokuvamile ahlose ukuhlinzeka ngezixazululo ezingabizi kakhulu zezinhlelo zokusebenza zokuthwebula izithombe, okwenza kube nebhalansi phakathi kokusebenza nokuthengeka.
Kubalulekile ukuhlola izidingo ezithile zohlelo lokusebenza lombono womshini wakho bese ukhetha izici zamalensi ezifanelana kangcono nezidingo zakho.
