Iilensi ze-Industrial zisetyenziswa ngokubanzi kwintsimi yoshishino kwaye yenye yeentlobo ze-lens eziqhelekileyo.Iindidi ezahlukeneyo zeelensi zoshishino zingakhethwa ngokweemfuno ezahlukeneyo kunye neemeko zesicelo.

Uzahlula njani iilensi zamashishini?

Iilensi zamashishiniinokwahlulwa ibe ziindidi ezahlukeneyo ngokwemigangatho yokwahlulahlula.Iindlela zokuhlela eziqhelekileyo zezi zilandelayo:

Ukuhlelwa okusekelwe kwisakhiwo selensi. 

Ngokwesakhiwo se-lens se-lens, iilensi zoshishino zinokwahlulwa zibe yi-lens enye (efana ne-convex lens, i-concave lens), iilensi ezidibeneyo (ezifana ne-biconvex lens, i-biconcave lens), amaqela e-lens adibeneyo, njl.

Zihlelwe ngokobude bojoliso.

Ihlelwe ngokobude obugxilwe kwilensi,iilensi zamashishinizibandakanya iilensi ezibanzi, iilensi eziqhelekileyo, iilensi zetelephoto, njl.

Ihlelwe ngokwemimandla yesicelo.

Ihlelwe ngokwemimandla yesicelo se-lens, iilensi zemizi-mveliso zinokwahlulwa zibe ziilensi zombono womatshini, iilensi zokulinganisa ushishino, iilensi zokucinga zonyango, iilensi zemicroscope, njl.

Ihlelwe ngokohlobo lojongano.

Ihlelwe ngokohlobo lwe-interface ye-lens, iilensi ze-industrial ziquka i-C-mount, i-CS-mount, i-F-mount, i-M12-mount kunye nezinye iintlobo.

Ukuhlelwa ngokusekelwe kwiiparamitha zamehlo.

Iilensi zihlelwa ngokweeparamitha zazo zokubona, kubandakanywa ubude bojoliso, indawo yokuvula, indawo yokujonga, ukugqwetheka, i-astigmatism, isisombululo, njl.

Ilensi yoshishino

Uthini umahluko phakathi kweelensi zamashishini kunye neelensi ngokubanzi?

Ngotshintsho kwimfuno kunye nokuqhubela phambili kweteknoloji, umahluko kwiimpawu zokusebenza phakathiiilensi zamashishinikwaye iilensi zabathengi ngokubanzi ziphela ngokuthe ngcembe, kwaye ezinye iilensi zemizi-mveliso kunye neelensi eziqhelekileyo nazo zinokusetyenziswa ngokutshintshanayo.Ngokubanzi, umahluko phakathi kweelensi zamashishini kunye neelensi ngokubanzi zimi ngolu hlobo lulandelayo:

Iimpawu ezahlukeneyo ze-optical

Xa kuthelekiswa neelensi eziqhelekileyo, iilensi zamashishini zineemfuno eziphezulu zomgangatho womfanekiso kunye nokuchaneka.Ngokuqhelekileyo banokuphazamiseka okuphantsi, i-chromatic aberration kunye nokunciphisa ukukhanya, ukuqinisekisa ukuchaneka komfanekiso kunye nokuthembeka.Iilensi ngokubanzi zinokuba nokulalanisa okuthile kwezinye iiparamitha, ikakhulu zilandela iziphumo ezingcono zobugcisa kunye namava omsebenzisi.

Iinjongo zoyilo ezahlukeneyo

Iilensi zamashishiniubukhulu becala zenzelwe usetyenziso lwemizi-mveliso njengombono womatshini, ulawulo oluzenzekelayo, umlinganiselo kunye nohlalutyo.Zenzelwe ukuhlangabezana nokuchaneka okuphezulu, isisombululo esiphezulu kunye neemfuno zokuzinza.Iilensi ngokubanzi ziyilelwe ubukhulu becala ukufota, ifilim kunye nezicelo zikamabonakude, kwaye zinike ingqwalasela engakumbi ekusebenzeni kwemifanekiso kunye neziphumo zobugcisa.

Iindlela ezahlukeneyo zokugxila

Iilensi ngokubanzi zivame ukuba nomsebenzi we-autofocus, onokuthi ulungelelanise ngokuzenzekelayo ugxininiso ngokwendawo kunye nesihloko.Iilensi zemizi-mveliso zihlala zisebenzisa ugxininiso lwezandla, kwaye abasebenzisi kufuneka bahlengahlengise ubude bendawo ekugxilwe kuyo kwaye bagxininise ukuziqhelanisa neemeko ezahlukeneyo zosetyenziso lweshishini kunye neemfuno.

Umahluko ekomeleleni kunye nokuguquguquka

Iilensi zamashishiniKufuneka imelane nemekobume yemizi-mveliso erhabaxa, enje ngamaqondo obushushu aphezulu naphantsi, ukufuma kunye nokungcangcazela, ngoko ke badla ngokufuna ukuhlala ixesha elide kunye nokuguquguquka.Xa kuthelekiswa, iilensi ngokubanzi zenzelwe ukuba zibe khaphukhaphu, zithwale kwaye zithwale lula, zenze kube lula ukuzisebenzisa kwiindawo eziqhelekileyo.
