Types yeIndustrial lensmount

Iko kune kunyanya ina mhando dzechimiro, dzinoti F-gomo, C-gomo, CS-gomo uye M12 gomo.Iyo F-Mount ndeye general-chinangwa interface, uye inowanzo fanirwa nemalenzi ane focal kureba kupfuura 25mm.Kana iyo yakatarisa kureba kwechinangwa lens isingasviki 25mm, nekuda kwehukuru hudiki hwechinangwa lens, iyo C-gomo kana CS-gomo inoshandiswa, uye vamwe vanoshandisa iyo M12 interface.

Musiyano uripo pakati peC gomo neCS mount

Misiyano pakati peC uye CS interfaces ndeyokuti chinhambwe kubva pakatarisana nepamusoro pe lens uye kamera kusvika kune yakatarisa ndege ye lens (nzvimbo iyo CCD photoelectric sensor yekhamera inofanira kuva) yakasiyana.Kureba kweiyo C-mount interface ndeye 17.53mm.

A 5mm C/CS adapta mhete inogona kuwedzerwa kune CS-gomo lens, kuitira kuti igone kushandiswa neC-mhando makamera.

Basic parameters yeindasitiri lenses

Nzvimbo yekuona (FOV):

FOV inoreva huwandu hunooneka hwechinhu chakacherechedzwa, kureva, chikamu chechinhu chakabatwa nesensor yekamera.(Kuwanda kwendima yekuona chinhu chinofanira kunzwisiswa mukusarudzwa)

Munda wekuona

Nzvimbo Yekushanda (WD):

Zvinoreva chinhambwe kubva kumberi kwelenzi kuenda kuchinhu chiri kuedzwa.Kureva, kureba kwepamusoro kwekufungidzira kwakajeka.

Resolution:

Iyo diki inosiyaniswa saizi yechinhu pane yakaongororwa chinhu chinogona kuyerwa neiyo imaging system.Muzviitiko zvakawanda, iyo idiki ndima yekuona, zviri nani kugadzirisa.

Kudzama kwemaonero (DOF):

Iko kugona kwelenzi kuchengetedza iyo inodiwa kugadzirisa kana zvinhu zviri padyo kana kure kure kubva kune yakanyanya kutariswa.

Mamwe maparameter emaindasitiri lenzi

Photosensitive chip size:

Saizi yenzvimbo inoshanda yekamera sensor chip, kazhinji inoreva saizi yakachinjika.Iyi parameter yakakosha kwazvo kuona iyo yakakodzera lens kuyera kuti uwane iyo inodiwa ndima yekuona.Iyo lens primary magnification ratio (PMAG) inotsanangurwa nechiyero chehukuru hwe sensor chip kumunda wekuona.Kunyangwe iwo akakosha ma paramita achisanganisira saizi uye munda wekutarisa weiyo photosensitive chip, PMAG haisi yekutanga parameter.

Hurefu hwekutarisa (f):

“Focal kureba chiyero chekudzika kana kutsauka kwechiedza muoptical system, iyo inoreva chinhambwe kubva pakati pekuona kwelenzi kusvika pakatarisana nekuunganidzwa kwechiedza.Iriwo chinhambwe kubva pakati pe lens kuenda kundege yekufungidzira senge firimu kana CCD mune kamera.f={chinhambwe chekushanda/munda wekuona rutivi rurefu (kana rutivi rupfupi)}XCCD kureba rutivi (kana rutivi rupfupi)

Kurudziro yehurefu hwefocal: iyo idiki iyo yakatarisa kureba, yakakura kudzika kwemunda;iyo idiki iyo yakatarisa kureba, iyo yakakura kukanganisa;iyo idiki iyo yakatarisa kureba, yakanyanya kukomba iyo vignetting phenomenon, iyo inoderedza kuvhenekera kumucheto kweaberration.

Resolution:

Inoratidza hunhambwe hudiki pakati pemapoinzi maviri anogona kuwonekwa neseti yechinangwa lenzi

0.61x yakashandiswa wavelength (λ) / NA = resolution (μ)

Nzira yekuverenga iri pamusoro inogona kuverenga kugadzirisa, asi haisanganisi kukanganisa.

※ Iyo wavelength inoshandiswa i550nm

Tsanangudzo:

Nhamba yemitsara yakasviba nemichena inogona kuonekwa pakati pe1mm.Chikamu (lp)/mm.

Kukanganisa:

Chimwe chezviratidzo zvekuyera kushanda kwe lens ndiko kukanganisa.Inoreva mutsara wakatwasuka kunze kweakisi huru mundege yechidzidzo, inova curve mushure mekufananidzwa neoptical system.Iko kukanganisa kwekufungidzira kweiyi optical system inonzi distortion.Distortion aberrations inongokanganisa geometry yemufananidzo, kwete kupinza kwemufananidzo.

Aperture uye F-Nhamba:

Lenticular sheet chishandiso chinoshandiswa kudzora huwandu hwechiedza chinopfuura nepalenzi, kazhinji mukati melenzi.Isu tinoshandisa kukosha kweF kuratidza saizi yekuvhura, senge f1.4, F2.0, F2.8, nezvimwe.

Aperture uye F-Nhamba

Optical magnification:

Iyo formula inoshandiswa kuverenga iyo huru yekuyera reshiyo ndeiyi inotevera: PMAG = sensor saizi (mm) / munda wekuona (mm)

Ratidza kukura

Kukura kwekuratidzira kunoshandiswa zvakanyanya mumicroscope.Kukura kwekuratidzira kwechinhu chakayerwa kunoenderana nezvinhu zvitatu: kukwidziridzwa kwelenzi, saizi ye sensor chip yeindasitiri kamera (saizi yenzvimbo inotarirwa), uye saizi yekuratidzira.

Ratidza magnification = lens optical magnification × kuratidza saizi × 25.4 / rake diagonal size

Zvikamu zvikuru zvemaindasitiri lenzi

Classification

•Nekureba kwekutarisa: prime uye zoom

•Nekuvhura: buri rakagadzika uye buri rinoshanduka

•Nechimiro: C interface, CS interface, F interface, nezvimwe.

• Yakakamurwa nezvizhinji: yakagadziriswa magnification lens, inoenderera mberi zoom lens

•Malenzi akakosha anowanzo shandiswa muindasitiri yekuona muchina anosanganisira malenzi eFA, telecentric lenzi uye maikorosikopu emaindasitiri, nezvimwe.

Pfungwa huru dzinofanirwa kutariswa pakusarudza amuchina kuona lenzi:

1. Munda wekuona, kukwidziridzwa kwemaziso uye chinhambwe chekushanda chinodiwa: Pakusarudza lenzi, isu tichasarudza lens ine nzvimbo yakakura zvishoma yekuona pane chinhu chinoyerwa, kuitira kufambisa kutonga kwekufamba.

2. Hudzamu hwezvinodiwa mumunda: Pamapurojekiti anoda kudzika kwemunda, shandisa kaburi kadiki sezvinobvira;kana uchisarudza lenzi ine magnification, sarudza lenzi ine yakaderera magnification kusvika panobvumirwa chirongwa.Kana izvo zvinodikanwa zveprojekiti zvakanyanya kudiwa, ini ndinowanzo kusarudza yekucheka-kumucheto lens ine yakakwira kudzika kwemunda.

3. Sensor size uye kamera interface: Semuyenzaniso, iyo 2/3 ″ lens inotsigira yakakura maindasitiri kamera rake repamusoro i2/3 ″, haigone kutsigira maindasitiri makamera akakura kupfuura 1 inch.

4. Nzvimbo iripo: Hazvina musoro kuti vatengi vachinje saizi yemidziyo kana chirongwa ichi chiripo.
