Iilensi zamehlo ngoku zisetyenziswa ngokubanzi kwiinkalo ezahlukeneyo, kubandakanywa iikhamera, iiteleskopu, iimicroscopes, iinkqubo zelaser, unxibelelwano lwefiber optic, njl. Ngoyilo olugqwesileyo kunye nobugcisa bokuvelisa,iilensi zamehloinokuhlangabezana neemfuno ze-optical kwiimeko ezahlukeneyo zesicelo, ukubonelela ngokucacileyo nangokuchanekileyo ukubanjwa komfanekiso kunye nemisebenzi yokuhanjiswa kwe-optical.

Ilensi yokubona kufuneka idlule kumanyathelo ahlukeneyo afana noyilo, ukusetyenzwa, kunye novavanyo ngaphambi kokuba umke kumzi-mveliso.Uyilo linyathelo lokuqala, kwaye kubaluleke kakhulu ukuqonda iimfuno zelensi.

Uyilo lweelensi zamehlo

Ukuqonda iimfuno kunokunceda ukwenza ngokwezifiso iilensi kunye nabaqulunqi baqonde ngokuchanekileyo iimfuno zabathengi kwaye banike izisombululo ezihambelana neemfuno zangempela zesicelo.

Ke, yintoni ekufuneka iqondwe ukwenza ngokwezifiso kunye noyilo lweelensi zamehlo?

Iimfuno zemeko yesicelo

Okokuqala, kufuneka uxelele ngokucacileyo abachwephesha ukuba yiyiphi intsimi yesicelo esithile sokusebenzisa i-lens optical kunye nokuba zeziphi iimfuno zokusebenza.Iimeko ezahlukeneyo zesicelo zinokuba neemfuno ezahlukeneyo zeeparamitha, ukusebenza kwe-optical kunye nezixhoboiilensi zamehlo.

Ngokomzekelo, iindawo ezahlukeneyo zesicelo ezifana nombono wekhompyutheni, umlinganiselo wemizi-mveliso, kunye nokucinga kwezonyango zineemfuno ezahlukeneyo zeelensi.

Iimfuno zokusebenza zamehlo

Qonda iimfuno zeeparamitha ze-optical, kubandakanywa ubude bogxininiso, intsimi yokujonga, ukuphazamiseka, isisombululo, uluhlu olugxilwe, njl. Ezi parameters zihambelana ngokuthe ngqo nokusebenza kwenkqubo ye-optical system.Ngokusekwe kwiimfuno zesicelo, jonga ukuba ngaba uyilo olukhethekileyo lwe-optical luyafuneka, njengeelensi ze-aspherical, izihluzi ze-vignetting, njl.

Ukongezelela, uluhlu lwe-spectral lwesicelo se-lens kufuneka luqwalaselwe.Ngenxa yokuba uyilo lwe-lens kufuneka luthathele ingqalelo i-chromatic aberration, imathiriyeli kunye nezinye iimpawu, kuyimfuneko ukwazi uluhlu lwe-spectral lwelensi xa lusetyenziswa.

Ukuba usebenzisa ukukhanya kwe-monochromatic, njengokukhanya okubomvu, ukukhanya okuluhlaza, ukukhanya okuluhlaza okwesibhakabhaka, njl., okanye ukusebenzisa ukukhanya okumhlophe okugcweleyo, okanye ukusebenzisa kufutshane ne-infrared,I-infrared yamaza amafutshane, i-infrared yamaza aphakathi, i-infrared yamaza amade, njl.

Iimfuno zeparamitha yoomatshini

Ukongeza kwiimfuno zentsebenzo ye-optical, ukuyila i-lens kufuna ukuqonda iimfuno zemishini, ezifana nobukhulu be-lens, ubunzima, ukuzinza komatshini, njl.

Siimfuno ezikhethekileyo zokusingqongileyo

Iilensi ze-Optical ziya kusebenza kwindawo ethile, kwaye impembelelo yezinto ezisingqongileyo ezifana nobushushu, ukufuma, kunye noxinzelelo kwi-lens kufuneka ziqwalaselwe.Ukuba indawo yokusebenza inzima okanye kukho iimfuno ezikhethekileyo, i-lens optical idinga ukukhuselwa okanye izinto ezikhethekileyo ezikhethiweyo.

Umthamo wemveliso kunye neemfuno zeendleko

Abaqulunqi baya kugqiba inkqubo yokuvelisa kunye neendleko ze-lens optical ngokusekelwe kwiimfuno zesicelo kunye neemfuno zevolumu yokuvelisa.Ikakhulu ibandakanya ukukhetha iindlela ezifanelekileyo zokusebenza, izixhobo kunye nobugcisa bokugquma, kunye novavanyo lweendleko kunye nolawulo.
