Ubwoko Byaingandamount

Hariho ubwoko bune bwimiterere, aribwo F-mount, C-mount, CS-mount na M12 mount.F-mount ni rusange-intego-rusange, kandi mubisanzwe ikwiranye ninzira zifite uburebure burenze 25mm.Iyo uburebure bwibanze bwibikoresho bitarenze munsi ya 25mm, bitewe nubunini buke bwibikoresho bifatika, C-mount cyangwa CS-mount ikoreshwa, kandi bamwe bakoresha interineti M12.

Itandukaniro riri hagati ya C mount na CS

Itandukaniro riri hagati ya C na CS ni uko intera iva hejuru yinteguza ya kamera na kamera kugera kumurongo wibanze wa lens (umwanya aho sensor ya CCD ifotora ya kamera igomba kuba) itandukanye.Intera ya C-mount ya interineti ni 17.53mm.

Impeta ya 5mm C / CS irashobora kongerwaho lens ya CS-mount, kugirango ikoreshwe na kamera yo mu bwoko bwa C.

Ibipimo fatizo byinzira zinganda

Umwanya wo kureba (FOV):

FOV bivuga urwego rugaragara rwibintu byarebwaga, ni ukuvuga igice cyikintu cyafashwe na sensor ya kamera.(Urwego rwumwanya wo kureba ni ikintu kigomba kumvikana muguhitamo)

Umwanya wo kureba

Intera y'akazi (WD):

Yerekeza ku ntera kuva imbere yintebe kugeza ku kintu kiri munsi yikizamini.Nukuvuga, intera yubuso bwo kwerekana amashusho neza.

Umwanzuro:

Ingano ntoya itandukanya ingano yibintu byagenzuwe bishobora gupimwa na sisitemu yo gufata amashusho.Mubihe byinshi, ntoya murwego rwo kureba, nibyiza gukemura.

Ubujyakuzimu bwo kureba (DOF):

Ubushobozi bwa lens kugirango bugumane ibyifuzo byifuzwa mugihe ibintu byegeranye cyangwa biri kure yibitekerezo byiza.

Ubujyakuzimu

Ibindi bipimo byainganda

Ingano ya chip ifotora:

Ingano yubunini bwa kamera sensor ya chip, mubisanzwe yerekeza kubunini bwa horizontal.Iyi parameter ningirakamaro cyane kugirango umenye lens ikwiye kugirango ubone umurima wifuzwa.Ikigereranyo cyibanze cyo gukuza (PMAG) gisobanurwa nigipimo cyubunini bwa sensor chip kumurima wo kureba.Nubwo ibipimo fatizo birimo ubunini n'umurima wo kureba chip ifotora, PMAG ntabwo aribintu shingiro.

Ingano ya chip

Uburebure bwibanze (f):

“Uburebure bwibanze ni igipimo cyo kwibanda cyangwa gutandukana k'umucyo muri sisitemu ya optique, bivuze intera iri hagati ya optique yo hagati ya lens kugeza aho kwibanda ku gukusanya urumuri.Nubundi intera iri hagati ya lens kugeza indege yerekana amashusho nka firime cyangwa CCD muri kamera.f = {intera ikora / umurima wo kureba uruhande rurerure (cyangwa uruhande rugufi)} XCCD uruhande rurerure (cyangwa uruhande rugufi)

Ingaruka yuburebure bwibanze: ntoya uburebure bwibanze, nuburebure bwumurima;ntoya uburebure burebure, niko kugoreka;ntoya uburebure bwibanze, niko bikomeye cyane vignetting phenomenon, igabanya kumurika kumpera ya aberration.

Umwanzuro:

Yerekana intera ntoya hagati yingingo 2 zishobora kugaragara nurutonde rwibintu bifatika

0,61x yakoresheje uburebure bwumurongo (λ) / NA = gukemura (μ)

Uburyo bwo kubara hejuru burashobora kubara muburyo bwo kubara imyanzuro, ariko ntiburimo kugoreka.

Ngth Uburebure bwakoreshejwe ni 550nm

Igisobanuro:

Umubare wumurongo wumukara numweru urashobora kugaragara hagati ya 1mm.Igice (lp) / mm.

Kugoreka:

Kimwe mu bipimo byo gupima imikorere ya lens ni aberration.Yerekeza kumurongo ugororotse hanze yingenzi nyamukuru mu ndege yikintu, ihinduka umurongo nyuma yo kwerekanwa na sisitemu ya optique.Ikosa ryerekana amashusho yiyi sisitemu optique yitwa kugoreka.Kugoreka kugoreka bigira ingaruka gusa kuri geometrie yishusho, ntabwo ubukana bwishusho.

Aperture na F-Umubare:

Urupapuro rwitwa lenticular ni igikoresho gikoreshwa mugucunga ingano yumucyo unyura mumurongo, mubisanzwe imbere.Dukoresha agaciro ka F kugirango tugaragaze ubunini bwa aperture, nka f1.4, F2.0, F2.8, nibindi.

Aperture na F-Umubare

Gukuza neza:

Inzira ikoreshwa mukubara igipimo nyamukuru cyo gupima niyi ikurikira: PMAG = ingano ya sensor (mm) / umurima wo kureba (mm)

Erekana gukuza

Kwerekana gukuza gukoreshwa cyane muri microscopi.Kwerekana gukuza ibintu byapimwe biterwa nibintu bitatu: gukuza optique ya lens, ingano ya sensor chip ya kamera yinganda (ubunini bwubuso bugenewe), nubunini bwerekana.

Erekana gukuza = lens optique yo gukuza × kwerekana ingano × 25.4 / ubunini bwa diagonal

Ibyiciro byingenzi byinganda

Ibyiciro

• Kuburebure bwibanze: prime na zoom

• Kubijyanye na aperture: aperture ihamye kandi ihindagurika

• Ukoresheje interineti: C Imigaragarire, CS ya CS, Imigaragarire ya F, nibindi.

• Igabanijwemo na benshi: lens yogukuza neza, lens zoom zo guhoraho

• Lens zingenzi cyane zikoreshwa mubikorwa byo kureba imashini cyane cyane zirimo lens ya FA, lens ya telecentric na microscopes yinganda, nibindi.

Ingingo z'ingenzi zigomba kuzirikana muguhitamo aimashini yerekana imashini:

1. Umwanya wo kureba, gukuza optique hamwe nintera yakazi ikora: Mugihe duhisemo lens, tuzahitamo lens ifite umurima munini muto wo kureba kuruta ikintu ugomba gupimwa, kugirango tworohereze kugenzura ibikorwa.

2. Ubujyakuzimu bwibisabwa mu murima: Kubikorwa bisaba ubujyakuzimu bwumurima, koresha aperture ntoya ishoboka;mugihe uhitamo lens hamwe no gukuza, hitamo lens hamwe no gukuza gake nkuko umushinga ubyemerera.Niba umushinga usabwa cyane, ndashaka guhitamo icyuma gipima uburebure bwimbitse bwumurima.

3. Ingano ya Sensor hamwe na kamera ya kamera: Kurugero, lens ya 2/3 ″ ishyigikira kamera nini yinganda nini ni 2/3 ″, ntishobora gushyigikira kamera yinganda zirenze santimetero 1.

4. Umwanya uboneka: Ntabwo bidashoboka ko abakiriya bahindura ingano yibikoresho mugihe gahunda itabishaka.
