Hom ntawmkev lag luam lensMount

Muaj plaub hom interface, uas yog F-mount, C-mount, CS-mount thiab M12 mount. F-mount yog lub hom phiaj dav dav, thiab feem ntau haum rau cov lo ntsiab muag nrog lub focal ntev ntev dua 25mm. Thaum lub focal ntev ntawm lub hom phiaj lens tsawg dua li 25 hli, vim qhov me me ntawm lub hom phiaj lens, C-mount lossis CS-mount yog siv, thiab qee qhov siv M12 interface.

Qhov sib txawv ntawm C mount thiab CS mount

Qhov sib txawv ntawm C thiab CS interfaces yog qhov kev ncua deb ntawm qhov chaw ntawm lub lens thiab lub koob yees duab mus rau lub dav hlau focal ntawm lub lens (txoj hauj lwm uas CCD photoelectric sensor ntawm lub koob yees duab yuav tsum yog) txawv. Qhov kev ncua deb rau C-mount interface yog 17.53mm.

Lub nplhaib 5 hli C / CS tuaj yeem muab ntxiv rau CS-mount lens, kom nws tuaj yeem siv nrog C-hom koob yees duab.

Qhov txawv ntawm C mount thiab CS mount

Basic parameters ntawm industrial lo ntsiab muag

Field of View (FOV):

FOV hais txog qhov pom ntau yam ntawm cov khoom pom, uas yog, ib feem ntawm cov khoom raug ntes los ntawm lub koob yees duab sensor. (Qhov ntau ntawm qhov kev pom yog qee yam uas yuav tsum tau nkag siab hauv kev xaiv)

Thaj chaw saib

Ua haujlwm nrug (WD):

Hais txog qhov kev ncua deb ntawm lub lens pem hauv ntej mus rau qhov khoom nyob rau hauv kev sim. Ntawd yog, qhov deb ntawm qhov chaw kom pom tseeb.

Kev daws teeb meem:

Qhov me me tshaj qhov txawv ntawm qhov loj me ntawm cov khoom kuaj xyuas uas tuaj yeem ntsuas los ntawm cov duab kos duab. Feem ntau, qhov me me ntawm qhov kev pom, qhov kev daws teeb meem zoo dua.

Qhov tob ntawm qhov pom (DOF):

Lub peev xwm ntawm lub lens kom tswj tau qhov kev daws teeb meem xav tau thaum cov khoom nyob ze lossis deb ntawm qhov ua kom pom tseeb zoo tshaj plaws.

Qhov tob ntawm kev pom

Lwm yam parameters ntawmkev lag luam lo ntsiab muag

Photosensitive nti loj:

Qhov zoo ntawm thaj tsam loj ntawm lub koob yees duab sensor nti, feem ntau yog hais txog kab rov tav loj. Qhov kev ntsuas no tseem ceeb heev los txiav txim siab qhov kev ntsuas lub lens kom tau txais qhov xav tau ntawm qhov pom. Lub lens thawj magnification piv (PMAG) yog txhais los ntawm qhov piv ntawm qhov loj ntawm lub sensor nti mus rau qhov pom. Txawm hais tias qhov yooj yim tsis muaj xws li qhov loj me thiab qhov chaw ntawm kev pom ntawm cov duab photosensitive nti, PMAG tsis yog qhov yooj yim parameter.

Photosensitive nti loj

Focal ntev (f):

"Focal length yog ib qho kev ntsuas ntawm qhov concentration lossis divergence ntawm lub teeb nyob rau hauv ib qho kev kho qhov muag system, uas yog hais txog qhov kev ncua deb ntawm qhov chaw kho qhov muag ntawm lub lens mus rau lub tsom xam ntawm lub teeb sib sau ua ke. Nws tseem yog qhov kev ncua deb ntawm qhov chaw ntawm lub lens mus rau lub dav hlau imaging xws li zaj duab xis lossis CCD hauv lub koob yees duab. f = {ua hauj lwm nrug / teb ntawm saib ntev sab (los yog sab luv)}XCCD ntev sab (los yog sab luv)

Kev cuam tshuam ntawm focal ntev: qhov me me ntawm qhov focal ntev, qhov ntau dua qhov tob ntawm qhov chaw; qhov me me qhov focal ntev, qhov ntau dua qhov distortion; qhov me me ntawm qhov focal ntev, qhov loj dua qhov tshwm sim vignetting, uas txo cov illumination ntawm ntug ntawm lub aberration.

Kev daws teeb meem:

Qhia qhov tsawg kawg nkaus nyob deb ntawm 2 cov ntsiab lus uas tuaj yeem pom los ntawm cov phiaj xwm lo ntsiab muag

0.61x siv wavelength (λ) / NA = daws teeb meem (μ)

Txoj kev suav saum toj no tuaj yeem suav qhov kev daws teeb meem, tab sis tsis suav nrog kev cuam tshuam.

※ Lub wavelength siv yog 550nm

Txhais:

Tus naj npawb ntawm cov kab dub thiab dawb tuaj yeem pom hauv nruab nrab ntawm 1 hli. Chav tsev (lp) / mm.

MTF (Modulation Transfer Function)

MTF

Distortion:

Ib qho ntawm cov ntsuas ntsuas kev ua haujlwm ntawm lub lens yog aberration. Nws yog hais txog txoj kab ncaj nraim sab nraud ntawm lub ntsiab axis hauv lub dav hlau ntawm qhov kev kawm, uas dhau los ua ib qho nkhaus tom qab tau pom los ntawm qhov system kho qhov muag. Cov duab yuam kev ntawm no optical system hu ua distortion. Distortion aberrations tsuas yog cuam tshuam rau geometry ntawm daim duab, tsis yog lub sharpness ntawm daim duab.

Aperture thiab F-Number:

Ib daim ntawv lenticular yog ib yam khoom siv los tswj cov teeb pom kev los ntawm lub lens, feem ntau hauv lub lens. Peb siv tus nqi F los qhia qhov loj me, xws li f1.4, F2.0, F2.8, thiab lwm yam.

Aperture thiab F-Number

Optical magnification:

Cov mis siv los xam qhov piv ntawm qhov loj me yog raws li hauv qab no: PMAG = sensor loj (mm) / teb pom (mm)

Zaub magnification

Zaub magnification yog dav siv nyob rau hauv microscopy. Qhov kev nthuav dav ntawm cov khoom ntsuas yog nyob ntawm peb yam: qhov muag pom ntawm lub lens, qhov loj ntawm lub sensor nti ntawm lub koob yees duab muaj (qhov loj ntawm lub hom phiaj), thiab qhov loj ntawm cov zaub.

Zaub magnification = lens optical magnification × zaub loj × 25.4 / rake kab pheeb ces kaum loj

Cov qeb tseem ceeb ntawm kev lag luam lo ntsiab muag

Kev faib tawm

• Los ntawm focal ntev: prime thiab zoom

•Los ntawm aperture: ruaj aperture thiab hloov pauv aperture

• Los ntawm interface: C interface, CS interface, F interface, thiab lwm yam.

• Faib los ntawm ntau yam: tsau magnification lens, nruam zoom lens

•Cov lo ntsiab muag tseem ceeb heev uas feem ntau siv hauv kev lag luam pom kev lag luam feem ntau suav nrog FA lo ntsiab muag, telecentric lo ntsiab muag thiab cov khoom siv microscopes, thiab lwm yam.

Cov ntsiab lus tseem ceeb uas yuav tsum tau coj mus rau hauv tus account hauv kev xaiv ibtshuab vision lens:

1. Kev pom kev pom, kev nthuav dav ntawm qhov muag pom thiab qhov xav tau ua haujlwm nyob deb: Thaum xaiv lub lens, peb yuav xaiv lub lens nrog qhov loj me me ntawm qhov pom dua li cov khoom yuav tsum ntsuas, txhawm rau txhawm rau tswj kev txav mus los.

2. Qhov tob ntawm qhov yuav tsum tau ua: Rau cov haujlwm uas xav tau qhov tob ntawm qhov chaw, siv lub aperture me me kom ntau li ntau tau; thaum xaiv ib lub lens nrog lub magnification, xaiv lub lens uas muaj qhov magnification tsawg npaum li qhov project tso cai. Yog tias qhov kev xav tau ntawm qhov project xav tau ntau dua, kuv nyiam xaiv lub lens txiav nrog qhov tob ntawm qhov chaw.

3. Sensor loj thiab lub koob yees duab interface: Piv txwv li, lub 2/3 "lens txhawb lub loj tshaj plaws industrial lub koob yees duab rake nto yog 2/3", nws tsis tuaj yeem txhawb cov koob yees duab loj dua 1 nti.

4. Qhov chaw muaj: Nws yog qhov tsis muaj tseeb rau cov neeg siv khoom los hloov qhov loj ntawm cov khoom siv thaum lub tswv yim yog xaiv tau.
