1.Amarangi yo gushyiramo lenzi mu nganda
Hari ibintu bitatu by'ingenzilentileUbwoko bw'aho ushyira: F-mount, C-mount, na CS-mount. F-mount ni ahantu hose hakoreshwa, muri rusange hakwiriye lenses zifite uburebure bwa focal burenga mm 25; mu gihe iyo uburebure bwa focal bwa lense y'icyitegererezo buri munsi ya mm 25, bitewe n'ingano nto ya lense y'icyitegererezo, hakoreshwa C-mount cyangwa CS-mount, kandi zimwe na zimwe zikoresha M12 mount.
Itandukaniro riri hagati ya Cshyirahona CSshyiraho:
Itandukaniro riri hagati ya C-mount na CS-mount riri hagati y’ubuso bw’aho lens-camera ihurira n’aho lens iherereye (aho sensor ya CCD image ya kamera iherereye): iyi ntera ni 17.53 mm kuri C-mount na 12.5 mm kuri CS-mount.
Lens za C-mount zikoreshwa na kamera za C-mount, naho lens za CS-mount zikoreshwa na kamera za CS-mount. Lens ya C-mount ikoreshwa na kamera ya CS-mount wongeyeho impeta ya adaptateri ya 5mm C/CS. Ariko, lens ya CS-mount ntishobora gukoreshwa na kamera ya C-mount.

2.Ibipimo by'ibanze by'indorerwamo z'inganda
1)Ikibuga cyo Kureba (FOV): Bivuga agace kagaragara k'ikintu kirimo kugaragara—cyane cyane igice cy'ikintu cyuzuza sensor y'ishusho ya kamera. (Ishusho ni ikintu cy'ingenzi cyo kuzirikana mu gihe uhitamo icyitegererezo.)
Imbonerahamwe y'aho ureba
2)Intera yo gukoreraho (WD): Bivuga intera iri hagati y'imbere y'aholentileku kintu kirimo gusuzumwa—cyane cyane intera iri hagati y’ubuso bw’aho ishusho igaragara. (Ibintu by’ingenzi bigomba kuzirikanwa mu gihe cyo guhitamo birimo niba intera yo gukora ishobora guhindurwa ndetse niba hari umwanya uhagije wo kuyishyiraho.)
3)Umusozo: Ingano y'ikintu gito cyane gishobora gukemuka ku kintu kirimo gusuzumwa sisitemu yo gufata amashusho ishobora kubona. Kenshi na kenshi, uko urwego rw'ishusho rugabanuka, niko imiterere yacyo iba myiza kurushaho.
4)Ubujyakuzimu bw'Umurima (DOF): Ubushobozi bw'ikirahuri cyo kugumana ubushobozi bukenewe iyo ikintu gishyizwe hafi cyangwa kure y'aho giherereye. (Ni ngombwa kumenya niba umukiriya afite ibisabwa byihariye bijyanye n'ubujyakuzimu bw'aho giherereye.)

3.Izindi parametre z'indobanure
1)Ingano y'icyuma gipima ishusho: Ingano y'agace gakora k'icyuma gipima ishusho ya kamera, akenshi yerekeza ku gipimo cy'ubutambitse. Iki gipimo ni ingenzi cyane mu kugena uburyo bwo kongera lenzi bukwiye kugira ngo hagerwe ku gice cyifuzwa cyo kureba. Ingano y'ibanze ya lenzi (PMAG) igenwa n'ikigereranyo cy'ingano y'icyuma gipima ishusho n'igice cyo kureba. Nubwo ingano y'icyuma gipima ishusho n'igice cyo kureba ari ibipimo by'ibanze, PMAG ubwayo ntabwo ishyirwa mu cyiciro kimwe.
Ishusho y'igishushanyo mbonera cy'urupapuro rugaragaza imiterere y'izuba
2)Uburebure bw'ifatizo (f): Igipimo cy'urumuri ruhurirana cyangwa rutandukanye muri sisitemu y'urumuri, gisobanurwa nk'intera iri hagati y'urumuri rw'urumurilentilekugera ku gice cy'ingenzi aho urumuri ruhurira. Muri kamera, yerekeza ku ntera iri hagati y'ikirahuri kugeza ku gice cy'ifoto (nk'ifilime cyangwa senseri ya CCD). (Formula yo kwibuka): f = {Intera yo gukorera / Uruhande rurerure (cyangwa uruhande rugufi) rw'aho ureba} × Uruhande rurerure (cyangwa uruhande rugufi) rwa CCD.
Ingaruka z'uburebure bw'inyuma ni izi zikurikira: Uko uburebure bw'inyuma burushaho kuba bugufi, ni ko uburebure bw'inyuma burushaho kuba bwinshi; uko uburebure bw'inyuma burushaho kuba bugufi, ni ko uburebure bw'inyuma burushaho kuba bwinshi; kandi uko uburebure bw'inyuma burushaho kuba bugufi, ni ko uburebure bw'inyuma burushaho kuba bubi, bigatuma urumuri rugabanuka ku nkengero z'ishusho.
3)Umusozo: Igaragaza itandukaniro rito riri hagati y'ingingo ebyiri rigaragazwa n'itsinda ry'indorerwamo zireba kure.
0.61 × Uburebure (λ) / NA = Icyemezo (μ)
Uburyo bwo kubara bwavuzwe haruguru bushobora kugena igisubizo mu buryo bw'imitekerereze, ariko ntabwo busobanura kugoreka.
※ Uburebure bw'umuraba bwakoreshejwe: 550nm
4)Ubutegetsi bwo gukemura ibibazo: Umubare w'imirongo y'umukara n'umweru ugaragara mu gice cya mm 1; igice: (lp) / mm.

5)Kugoreka: Kimwe mu bipimo byakoreshejwe mu gusuzumalentileImikorere. Bivuga ikosa ryo gufata amashusho muri sisitemu y'amashusho aho imirongo igororotse iri mu gice cy'ishusho—ariko idaca mu murongo w'amashusho—igaragara nk'imirongo igoramye mu ishusho ivuyemo. Ihindagurika ry'ishusho rigira ingaruka gusa ku miterere y'ishusho, ntabwo bigira ingaruka ku buhanga bwayo.
6)Umwobo n'umubare wa F: Umwobo ni uburyo—ubusanzwe buba buri imbere muri lens—bugenzura ingano y'urumuri rwinjira muri lens. Ingano y'umwobo igaragazwa hakoreshejwe imibare ya F, nka F1.4, F2.0, na F2.8.
Imbonerahamwe y'agaciro k'ahabohotse
7)Kwagura urumuri: Ifishi ikoreshwa mu kubara ubwiyongere bw'ibanze ni iyi ikurikira: PMAG = Ingano ya sensor y'ishusho (mm) / Aho igaragara (mm).
8)Gupima ecran: Kuzamura ecran bikoreshwa cyane muri mikorosikopi. Kuzamura ecran y'ikintu kirimo kurebwa biterwa n'ibintu bitatu: kuzamura optique y'ikimenyetsolentile, ingano y'icyuma gipima amashusho cya kamera y'inganda (imiterere ya sensor), n'ingano y'icyuma gipima amashusho.
Kuzamura isura = Kuzamura isura y'ijisho × Ingano ya ecran × 25.4 / Ingano ya diagonal ya sensor
4.Ibyiciro by'ingenzi by'indorerwamo z'inganda
Uburyo bwo gushyira mu byiciro:
1) Ishyirwa mu byiciro hakurikijwe uburebure bw'ibanze: uburebure bw'ibanze buhamye n'uburebure bw'ibanze bwo gukurura;
2) Ishyirwa mu byiciro hakurikijwe umwobo: umwobo udahinduka n'umwobo uhindagurika;
3) Bishyirwa mu byiciro hakurikijwe uburyo bwo gushyiramo: C-mount, CS-mount, F-mount, nibindi;
4) Bishyirwa mu byiciro hakurikijwe uburyo bwo kongera: lenzi zo kongera ubushobozi buhamye n'indorerwamo zoom zihoraho;
Indorerwamo z'ingenzi zikoreshwa cyane mu nganda zikora imashini zireba cyane cyane zirimo indorerwamo za FA, indorerwamo za telecentric, n'indorerwamo za mikorosikopi z'inganda.
Ubwoko butandukanye bw'indorerwamo z'inganda
5.Ibintu by'ingenzi bigomba kwitabwaho mu guhitamo lenzi zo mu nganda
Iyo uhisemolentile, tugomba kubanza kumenya ibyo umukiriya akeneye:
1) Aho umuntu areba, kongera ubwiza bw'amajwi, n'intera yifuza yo gukoreramo: Iyo duhitamo lenzi, duhitamo ifite aho ireba nini gato ugereranyije n'ikintu kirimo gusuzumwa kugira ngo tworohereze kugenzura imikorere.
2) Ubujyakuzimu bw'ibisabwa mu murima: Ku mishinga isaba uburebure bwihariye bw'ubutaka, koresha umwanya muto ushoboka; mu gihe uhitamo lens, hitamo uburebure buke bushoboka bwemewe n'imbogamizi z'umushinga. Ku bijyanye n'ikoreshwa rikomeye, shyira imbere lens nziza zitanga uburebure bwiza bw'ubutaka.
3) Ingano ya sensor n'uburyo kamera igaragaramo: Urugero, lensi ya 2/3″ ishyigikira ingano ntarengwa ya sensor ya kamera ikoreshwa mu nganda ya 2/3″; ntishobora gushyigikira kamera zikoreshwa mu nganda zifite sensor zirengeje santimetero 1.
4) Witondere guhuza urumuri n'aho ruturuka hanyuma uhitemo lenzi ikwiye.
5) Aho gushyira ibikoresho: Iyo igishushanyo mbonera cyamaze kugenwa, ntabwo bishoboka gusaba umukiriya guhindura ingano y'ibikoresho.
