Iilensi ze-optical ngoku zisetyenziswa kakhulu kwiinkalo ezahlukeneyo, kuquka iikhamera, iiteleskopu, iimayikroskopu, iinkqubo zelaser, unxibelelwano lwe-fiber optic, njl. Ngobuchule boyilo kunye nokuvelisa obugqwesileyo,iilensi ezibonakalayoinokuhlangabezana neemfuno ze-optical kwiimeko ezahlukeneyo zesicelo, ibonelela ngemisebenzi ecacileyo nechanekileyo yokubamba imifanekiso kunye nokudlulisa i-optical.

Ilensi ye-optical kufuneka idlule kumanyathelo ahlukeneyo afana noyilo, ukucubungula, kunye novavanyo ngaphambi kokuba iphume kumzi-mveliso. Uyilo linyathelo lokuqala, kwaye kubaluleke kakhulu ukuqonda iimfuno zelensi.

Uyilo lweelensi zokukhanya

Ukuqonda iimfuno kunokunceda ukwenziwa ngokwezifiso kweelensi zokukhanya kwaye abayili baqonde ngokuchanekileyo iimfuno zabathengi kwaye banike izisombululo ezihambelana neemfuno zokwenyani zesicelo.

Ngoko ke, yintoni ekufuneka iqondwe malunga nokwenza ngokwezifiso kunye noyilo lweelensi zokukhanya?

Iimfuno zesimo sesicelo

Okokuqala, kufuneka ubaxelele ngokucacileyo oochwephesha ukuba yintoni intsimi ethile yesicelo sokusebenzisa ilensi yokukhanya kunye neemfuno zokusebenza. Iimeko ezahlukeneyo zesicelo zinokuba neemfuno ezahlukeneyo zeparameters, ukusebenza kokukhanya kunye nezixhobo zeiilensi ezibonakalayo.

Umzekelo, amacandelo ahlukeneyo okusetyenziswa afana nombono wekhompyutha, ukulinganisa kwemizi-mveliso, kunye nemifanekiso yezonyango aneemfuno ezahlukeneyo zeelensi.

Iimfuno zokusebenza ezibonakalayo

Qonda iimfuno zeeparameter ze-optical, kubandakanya ubude be-focal, i-field of view, i-distortion, i-resolution, i-focus range, njl. Ezi parameters zinxulumene ngokuthe ngqo nokusebenza kwenkqubo ye-optical. Ngokusekelwe kwiimfuno zesicelo, misela ukuba ngaba kufuneka uyilo olukhethekileyo lwe-optical, olufana neelensi ze-aspherical, izihluzi ze-vignetting, njl.

Ukongeza, uluhlu lweespectral zokusetyenziswa kwelensi nalo kufuneka luqwalaselwe. Ngenxa yokuba uyilo lwelensi kufuneka luqwalasele ukuguquguquka kwe-chromatic, izinto kunye nezinye iimpawu, kuyimfuneko ukwazi uluhlu lweespectral zelensi xa isetyenziswa.

Ukuba usebenzisa ukukhanya okunombala omnye, njengokukhanya okubomvu, ukukhanya okuluhlaza, ukukhanya okuluhlaza okwesibhakabhaka, njl.njl., okanye usebenzisa ukukhanya okumhlophe okupheleleyo, okanye usebenzisa ukukhanya okukufutshane ne-infrared,i-infrared yamaza amafutshane, i-infrared yamaza aphakathi, i-infrared yamaza amade, njl. njl.

Ilensi yokukhanya

Iimfuno zeparameter zoomatshini

Ukongeza kwiimfuno zokusebenza kwe-optical, ukuyila ilensi kufuna ukuqonda iimfuno ze-mechanical, ezinje ngobukhulu belensi, ubunzima, uzinzo lwe-mechanical, njl. Ezi parameters zinefuthe ekufakeni nasekudibaniseni iilensi ze-optical.

Siimfuno ezithile zokusingqongileyo

Iilensi zokukhanya ziya kusebenza kwindawo ethile, kwaye impembelelo yezinto ezingqongileyo ezifana nobushushu, ukufuma, kunye noxinzelelo kwilensi kufuneka iqwalaselwe. Ukuba indawo yokusebenza inzima okanye kukho iimfuno ezikhethekileyo, ilensi yokukhanya kufuneka ikhuselwe okanye kukhethwe izixhobo ezikhethekileyo.

Ubungakanani bemveliso kunye neemfuno zeendleko

Abayili baya kugqiba inkqubo yemveliso kunye neendleko zelensi ye-optical ngokusekelwe kwiimfuno zesicelo kunye neemfuno zomthamo wemveliso. Oku kuquka ikakhulu ukukhetha iindlela ezifanelekileyo zokucubungula, izixhobo kunye nobuchwepheshe bokugquma, kunye novavanyo lweendleko kunye nolawulo.
