Mhando yelenzi yeindasitirigomo

Kune mhando ina dzeinterface, dzinoti F-mount, C-mount, CS-mount uye M12 mount. F-mount iinterface inoshandiswa zvakanyanya, uye inowanzo kukodzera malenzi ane urefu hwefocal hunopfuura 25mm. Kana urefu hwefocal hwe objective lens huri pasi pe25mm, nekuda kwehukuru hudiki hwe objective lens, C-mount kana CS-mount inoshandiswa, uye vamwe vanoshandisa M12 interface.

Musiyano uripo pakati peC mount neCS mount

Musiyano uripo pakati peC neCS interfaces ndewekuti daro kubva panzvimbo inobatwa lenzi nekamera kusvika panzvimbo inoonekwa nelenzi (nzvimbo inofanira kuva neCCD photoelectric sensor yekamera) rakasiyana. Daro reC-mount interface i17.53mm.

Ringi yeadapta ye5mm C/CS inogona kuwedzerwa kune lenzi yeCS-mount, kuitira kuti ikwanise kushandiswa nemakamera emhando yeC.

Zviyero zvepakutanga zvema lenses eindasitiri

Nzvimbo yekuona (FOV):

FOV inoreva nzvimbo inoonekwa yechinhu chakaonekwa, kureva chikamu chechinhu chakabatwa ne sensor yekamera. (Nzvimbo yenzvimbo yekuona chinhu chinofanira kunzwisiswa mukusarudza)

Munda wekuona

Kureba Kwebasa (WD):

Zvinoreva daro riri pakati pegirazi nechinhu chiri kuyedzwa. Kureva daro riri pamusoro pechinhu chiri kuratidzwa kuti chionekwe zvakajeka.

Kugadziriswa:

Saizi diki diki pane chinhu chakaongororwa chinogona kuyerwa nehurongwa hwemifananidzo. Kazhinji, kana nzvimbo yekuona iri diki, kunaka kwayo kunowedzera.

Kudzika kwemaonero (DOF):

Kugona kwelenzi kuchengetedza resolution inodiwa kana zvinhu zviri pedyo kana kure nepfungwa yakanakisisa.

Kudzika kwemaonero

Mamwe ma parameter emagirazi eindasitiri

Saizi yechipu inonzwa chiedza:

Saizi yenzvimbo inoshanda yechip ye sensor yekamera, inowanzo kureva saizi yakatambanuka. Iyi parameter yakakosha zvikuru pakuona chiyero chakakodzera che lens kuti uwane nzvimbo yekuona yaunoda. Iyo lens primary magnification ratio (PMAG) inotsanangurwa nechiyero chehukuru hwechip ye sensor kune nzvimbo yekuona. Kunyangwe ma parameter ekutanga achisanganisira saizi uye nzvimbo yekuona yechip inonzwa chiedza, PMAG haisi iyo parameter yekutanga.

Kureba kwefocal (f):

"Kureba kwefocal inzira yekuyera kuwanda kana kusiyana kwechiedza mu optical system, zvinoreva daro kubva pakati pe optical ye lens kusvika panowanikwa chiedza. Ndiwo daro kubva pakati pe lens kuenda kumufananidzo wefirimu kana CCD mu kamera. f={daro rekushanda/nzvimbo yekuona divi refu (kana divi pfupi)} XCCD divi refu (kana divi pfupi)

Kupesvedzera kwehurefu hwefocal: hurefu hwefocal hudiki, kudzika kwemunda kunowedzera; hurefu hwefocal hudiki, kukanganisa kunowedzera; hurefu hwefocal hudiki, chiitiko chekupenya chinowedzera kuipa, izvo zvinoderedza kupenya pamucheto wekusagadzikana.

Kugadziriswa:

Kusarongeka:

Chimwe chezviratidzo zvekuyera mashandiro e lenzi ndeyekusanzwisisana. Izvi zvinoreva mutsetse wakatwasuka uri kunze kwe axis huru mu plane yechinhu, iyo inova curve mushure mekutorwa mifananidzo ne optical system. Kukanganisa kwe imaging ye optical system iyi kunonzi distortion. Kusanzwisisana kwe distortion kunokanganisa chete geometry yemufananidzo, kwete kupinza kwemufananidzo.

Aperture neF-Number:

Pepa re lenticular mudziyo unoshandiswa kudzora huwandu hwechiedza chinopfuura nepa lenzi, kazhinji mukati me lenzi. Tinoshandisa F value kuratidza saizi yekuvhura, senge f1.4, F2.0, F2.8, nezvimwewo.

Aperture uye F-Number

Kukwidziridza kwemaziso:

Fomura inoshandiswa kuverenga chiyero chikuru chekuyera ndeiyi inotevera: PMAG = saizi yesensa (mm) / nzvimbo yekuona (mm)

Kukwidziridza kuratidzwa

Kukwidziridza kwechiratidzo kunoshandiswa zvakanyanya mu microscopy. Kukwidziridza kwechiratidzo kwechinhu chakayerwa kunoenderana nezvinhu zvitatu: kukwidziridza kwemaziso kwelenzi, saizi ye sensor chip yekamera yeindasitiri (hukuru hwenzvimbo yakanangwa), uye saizi yechiratidzo.

Kukwidziridza kuratidzwa = kukura kwegirazi remaziso × saizi yekuratidzwa × 25.4 / saizi yedhayagiramu yeraki

Mapoka makuru emalenzi eindasitiri

Kupatsanura

•Nekureba kwefocal: prime uye zoom

•Nekuvhura: vhura rakagadzika uye vhura rinoshanduka

•Nekushandisa interface: C interface, CS interface, F interface, nezvimwewo.

•Yakakamurwa nezvikamu zvakawanda: lenzi yekukudza yakagadziriswa, lenzi yekuzoom inoenderera mberi

•Magirazi anonyanya kukosha anoshandiswa muindasitiri yekuona kwemuchina anosanganisira magirazi eFA, magirazi e telecentric uye mamaikorosikopu eindasitiri, nezvimwewo.

Pfungwa huru dzinofanira kufungwa nadzo pakusarudzalenzi yekuona yemuchina:

1. Nzvimbo yekuona, kukura kwemaziso uye daro rinodiwa rekushanda: Pakusarudza lenzi, tichasarudza lenzi ine nzvimbo yekuona yakakura zvishoma pane chinhu chinofanira kuyerwa, kuitira kuti zvive nyore kudzora kufamba.

2. Zvinodiwa pakukura kwenzvimbo: Kune mapurojekiti anoda kudzika kwenzvimbo, shandisa mukana mudiki sezvinobvira; pakusarudza lenzi ine kukura, sarudza lenzi ine kukura kushoma zvichienderana nezvinodiwa neprojekiti. Kana zvinodiwa neprojekiti zvichinetsa, ndinosarudza lenzi yemazuva ano ine kudzika kwenzvimbo.

3. Saizi ye sensor uye interface yekamera: Semuenzaniso, lenzi ye 2/3″ inotsigira nzvimbo yakakura kwazvo yekamera yeindasitiri ine 2/3″, haigone kutsigira makamera eindasitiri akakura kupfuura 1 inch.

4. Nzvimbo iripo: Hazvina musoro kuti vatengi vachinje saizi yemidziyo kana chirongwa chacho chiri chekusarudza.
