Dab tsi yog qhov tseem ceeb hauv Kev Xaiv Lub StereoMicroscope

Dab tsi yog qhov tseem ceeb ntawm kev xaiv lub tso suab tso suab?

Stereo microscopes muaj cov yam ntxwv hauv qab no:

1. Sab laug thiab sab xis kab teeb nyob rau hauv lub binocular raj tsis yog tib yam, tab sis muaj ib lub kaum ntse ntse - lub ntim lub kaum sab xis (feem ntau yog 12 degrees --- 15 degrees), yog li cov duab muaj peb-dimensional kev nkag siab;

2. Cov duab yog upright, yooj yim rau kev khiav lag luam thiab dissect, vim hais tias lub prism nyob rau hauv lub eyepiece tig daim duab upside down;

3. Txawm hais tias qhov kev nthuav dav tsis zoo li ntawm lub tshuab ntsuas pa, nws qhov kev ua haujlwm ntev heev.

4. Qhov tob ntawm kev ua kom pom tseeb yog qhov loj, uas yooj yim los soj ntsuam cov txheej txheem tag nrho ntawm cov khoom hauv kev tshuaj xyuas.

5. Txoj kab uas hla ntawm qhov chaw saib yog loj.

Cov ntsiab lus tseem ceeb hauv kev xaiv lub stereo microscope:

1. Zoom ntau, magnification, teb saib thiab ua hauj lwm nrug

-- Cov neeg siv uas pib ua haujlwm ntawm tib qhov kev nthuav dav tsis xav tau ntau qhov zoom.

-- Ib qho kev zoom loj loj nrog kev kho kom zoo ntawm qhov qis mus rau siab yog qhov yuav tsum tau ua thaum qhov kev ua haujlwm xav tau kev tshawb nrhiav, nrhiav thiab ua qauv ua haujlwm.

-- Nyob rau tib qhov kev nthuav dav, qhov loj dua lossis me me ntawm qhov pom uas tuaj yeem pom nyob ntawm qhov muag. Qhov loj dua ntawm kev pom tso cai rau cov neeg siv kom zoo dua orientate tus qauv.

-- Qhov kev ua haujlwm loj dua txhais tau hais tias qhov kev ncua deb ntawm qhov saum toj ntawm cov qauv thiab nyob rau hauv pem hauv ntej ntawm lub hom phiaj pem hauv ntej lens, ua kom yooj yim rau kev tswj tus qauv thaum siv.

2. Qhov tob ntawm Field thiab Numerical Aperture (NA)

-- Siab dua NA ua rau muaj kev daws teeb meem siab dua, tab sis qhov tob ntawm thaj teb feem ntau txo qis.

-- Fusion Optics thev naus laus zis ua ke nrog kev daws teeb meem siab rau qhov tob ntawm thaj tsam ntau dua.

3. Optical zoo

-- Flat Field Optics: Kho cov duab flatness hla tag nrho cov khoom ntawm kev pom rau txhua daim ntawv thov.

-- Achromatic optics: Rau cov ntawv thov uas cov xim luam tawm tsis yog qhov tseem ceeb, tab sis feem ntau yog rau kev ntsuas cov yam ntxwv.

-- Apochromatic optics: Thaum saib cov qauv uas yuav tsum tau muaj xim siab heev, yuav tsum muaj qhov zoo ntawm optics thiab lub teeb pom kev zoo

-- Transmittance: Rau cov ntawv thov uas yuav tsum tau soj ntsuam cov ntsiab lus meej ntawm cov qauv, kev siv cov khoom siv kho qhov muag zoo nrog cov kev xa tawm zoo dua yuav muaj txiaj ntsig zoo dua. Rau cov ntawv thov xws li R & D, kev siv cov khoom siv hluav taws xob siab tuaj yeem muaj qhov sib txawv kiag li

-- Xim luam tawm: Yog tias pom qhov tseeb xim ntawm cov qauv yog qhov taw qhia tseem ceeb, ces qhov zoo ntawm optics thiab teeb pom kev zoo yuav tsum tau siv.
