Ubwoko yalens yingandaumusozi

Hariho cyane cyane ubwoko bune bwimikoreshereze, aribyo umusozi wa F-Fall, C - Umusozi, CS-Umusozi na M12 umusozi. F-Umusozi ni intego rusange, kandi muri rusange ibereye lens hamwe nuburebure bwibanze kurenza 25mm. Iyo uburebure bwibanze bwintego butari munsi ya 25mm, bitewe nubunini buke bwa lens, imisozi cyangwa CS-Umusozi ukoreshwa, kandi bamwe bakoresha Imigaragarire ya M12.

Itandukaniro riri hagati ya C Umusozi na CS

Itandukaniro riri hagati ya C na CS Intera ni iyo ntera iri hejuru yindimu na kamera yibanze yimyenda (umwanya wa ccd Phorafertric ya kamera igomba kuba) iratandukanye. Intera ya C-Imisozi ni 17.53mm.

Impeta ya 5mm c / cs id irashobora kongerwaho kuri lens ya CS-Umusozi, kugirango ikoreshwe na kamera ya C-Ubwoko.

Ibipimo byibanze byinganda

Umwanya wo kureba (Fov):

Fov bivuga urutonde rugaragara rwikintu cyagaragaye, ni ukuvuga, igice cyikintu cyafashwe na sensor ya kamera. (Urwego rwumurima wibireba ni ikintu kigomba kumvikana muguhitamo)

Umwanya wo kureba

Intera ikora (WD):

Bivuga intera uhereye imbere ya lens kubintu biri mubizamini. Ni ukuvuga, intera ndende yo gutekereza neza.

Icyemezo:

Ingano ntoya idahwitse ku kintu cyagenzuwe gishobora gupimwa na sisitemu yo gutekereza. Mubihe byinshi, bito murwego rwo kureba, nibyiza gukemura.

Ubujyakuzimu bwo kureba (DOF):

Ubushobozi bwa lens kugirango bugumane imyanzuro yifuzwa mugihe ibintu biri hafi cyangwa kure uhereye kumurwi wibanze.

Ubujyakuzimu

Ibindi bipimo byaLensrial Lens

Ingano ya Chip:

Ingano nziza ya kamera sensor chip, muri rusange bivuga ubunini butambitse. Iyi parameter ni ingenzi cyane kugena lens ikwiye kugirango ubone umurima wifuza. Ibipimo byibanze byibanze (PMag) bisobanurwa na gene yubunini bwa sensor chip kumurima. Nubwo ibipimo shingiro birimo ubunini numurima wa chip Photo, PMag ntabwo aribipimo shingiro.

Ingano ya Chip

Uburebure bwibanze (F):

"Uburebure bwibanze ni urugero rwo kwibandaho cyangwa gutandukana k'umucyo muri sisitemu ya optique, bivuga intera iri hagati y'intama ku giterane cyo mu mucyo. Nintera ni hagati ya lens indege kuri firime cyangwa CCD muri kamera. F = {Gukora Intera / Umwanya wo kureba uruhande rurerure (cyangwa kuruhande rugufi)} xccd uruhande rurerure (cyangwa kuruhande rugufi)

Ingaruka zuburebure bwibanze: Uburebure buto bwibanze, niko kwimbitse k'umurima; uburebure buto bwibanze, niko kugoreka; Uburebure buto bwibanze, bukomeye ibintu byangirika, bigabanya kumurika kuruhande rwibishuka.

Icyemezo:

Yerekana intera ntarengwa iri hagati yingingo 2 zishobora kugaragara ukoresheje lens zifatika

0.61x Yakoresheje Uburebure (λ) / NA = Icyemezo (μ)

Uburyo bwo kubara hejuru burashobora kubara imyanzuro, ariko ntabwo ikubiyemo kugoreka.

Uburebure bwa Waveley ikoreshwa ni 550nm

Gusuzugura:

Umubare wimirongo yumukara numweru urashobora kugaragara hagati ya 1mm. Igice (LP) / MM.

Kugoreka:

Kimwe mu bipimo byerekana imikorere yimyenda irashize. Bivuga kumurongo ugororotse hanze yinsanganyamatsiko nyamukuru mu ndege yisomo, ihinduka umurongo nyuma yo gushushanywa na sisitemu ya optique. Ikosa ryamashusho ryiyi sisitemu ya optique yitwa kugoreka. Kugoreka Ibihimbano bigira ingaruka gusa kuri geometrie yishusho, ntabwo ari ugukarira kw'ishusho.

Aperture na F-nimero:

Urupapuro rwibintu ni igikoresho gikoreshwa mu kugenzura ingano yumucyo unyura muri lens, mubisanzwe imbere muri lens. Dukoresha agaciro f kugirango tugaragaze ingano ya APERTURE, nka F1.4, F2.0, F2.8, nibindi.

Aperture na F-Umubare

Kuzana neza:

Formula ikoreshwa mu kubara igipimo nyamukuru gikabije ni gikurikira: PMag = Ingano ya sensor (MM) / Umwanya wo kureba (MM)

Kugaragaza

Kwerekana gukwega bikoreshwa cyane muri microscopi. Kugaragaza gukuza ikintu cyapimwe biterwa nibintu bitatu: gukuza kwa optique ya lens, ubunini bwa sensor chip ya kamera yinganda (ingano yintego.

Erekana Magnumedict = lens optique magnication × Erekana × 25.4 / ingano ya diagonal

Ibyiciro by'ingenzi bya lensring

Gutondekanya

• Muburebure bwibanze: Prime na Zoom

• Na Aperture: Apeture yagenwe na Aperture

• Na interineti: C Interface, CS IMIKORESHEREZE, FIMA, HOT.

• igabanijwe na benshi: lens yagenwe yagenwe, zororo zo muri zoom

• Lens ikomeye cyane ikoreshwa mu nganda za mashini zirimo fasire, lenter ya telente na microscope yinganda, nibindi

Ingingo z'ingenzi zigomba kuzirikana muguhitamo aImashini Icyerekezo Lens:

1. Umwanya wo kureba, gukuza neza kandi byifuzwa intera ikora: mugihe uhisemo lens, tuzahitamo lens hamwe numurima munini ugaragara, kugirango upimire.

2. Ubujyakuzimu bwibisabwa murima: Imishinga isaba ubujyakuzimu bwumurima, koresha umupaki muto bishoboka; Mugihe uhitamo lens hamwe no gukuza, hitamo lens hamwe nubukwe buke kugeza aho umushinga ushimangira. Niba ibisabwa byimishinga birasaba cyane, nkunda guhitamo lens yaciwe hamwe nubujyakuzimu bwinshi.

3. Ingano ya sensor na kamera: kurugero, lens 2/3 "zishyigikira kamera nini yinganda ni 2/3", ntishobora gushyigikira kamera yinganda nini kuruta santimetero 1.

4. Umwanya uboneka: Ntabwo bidashoboka kubakiriya guhindura ingano yibikoresho mugihe gahunda idahinduka.
