Cov teeb meem tshwm sim nrog stereomicroscopes thiab yuav daws lawv li cas
Stereoscopic microscope, tseem hu ua khoom microscope lossis dissecting microscope. Lub tshuab kuaj kab mob binocular hais txog cov cuab yeej pom kev zoo nrog lub suab tso suab zoo, uas saib cov khoom los ntawm cov ces kaum sib txawv thiab ua rau pom lub suab ntawm ob lub qhov muag. Kev soj ntsuam lub cev tsis tas yuav tsum muaj kev ua haujlwm lossis kev tsim khoom, thiab tuaj yeem tso ncaj qha rau hauv qab lub lens nrog lub teeb pom kev zoo rau kev soj ntsuam, zoo li nws yog upright, ua rau nws yooj yim rau kev khiav lag luam thiab dissect. Lub teb ntawm kev pom muaj ib txoj kab uas hla loj, tab sis cov khoom soj ntsuam yuav tsum muaj qhov loj ntawm tsawg dua 200 npaug. Cov yam ntxwv ntawm lub stereo microscope yog raws li nram no: sab laug thiab sab beams nyob rau hauv lub binocular raj tsis yog tib yam, tab sis muaj ib tug tej lub kaum sab xis - lub volumetric kaum feem ntau yog 12 degree mus rau 15 degree, yog li cov duab muaj peb-dimensional kev nkag siab. Qhov no yog vim lub prism hauv qab lub eyepiece inverts daim duab; Txawm hais tias qhov kev nthuav dav tsis zoo li lub tshuab ntsuas pa, nws muaj qhov ua haujlwm ntev, qhov tob ntawm kev tsom xam, thiab yooj yim los soj ntsuam tag nrho cov txheej txheem ntawm cov khoom raug kuaj, nrog rau qhov loj ntawm qhov pom txoj kab uas hla.
Cov teeb meem thiab kev daws teeb meem rau stereomicroscopes:
1. Lub teb ntawm kev pom yog qhov muag tsis pom lossis tej zaum yuav muaj av ntawm cov qauv, av ntawm qhov chaw ntawm lub qhov muag, cov av ntawm qhov chaw ntawm lub hom phiaj lens, thiab cov av ntawm qhov chaw ua haujlwm. Ntxuav cov av ntawm qhov chaw ntawm cov qauv, qhov muag, lub hom phiaj, thiab cov rooj ua haujlwm raws li qhov xwm txheej.
2. Yog vim li cas rau qhov tsis coincidence ntawm dual dluab yuav yog vim tsis raug hloov ntawm cov menyuam kawm ntawv nyob deb. Yuav kho cov menyuam kawm ntawv nyob deb. Yog tias cov duab dual tsis sib tshooj, nws yuav yog vim qhov pom kev tsis raug thiab tuaj yeem hloov kho dua. Xwb, yog hais tias qhov magnification ntawm sab laug thiab sab xis eyepieces txawv, xyuas cov eyepieces thiab reinstall lawv nrog tib magnification.
3. Yog tias daim duab tsis meej, nws yuav yog vim muaj av ntawm lub hom phiaj lens. Thov ntxuav lub hom phiaj lens.
4. Yog tias daim duab tsis meej thaum zoom, nws yuav yog vim qhov pom kev tsis raug thiab tsom. Koj tuaj yeem kho qhov pom lub kaum ntse ntse thiab ua kom pom tseeb dua.
5. Yog tias lub teeb hluav taws xob nquag kub hnyiab tawm thiab lub teeb flickers tsis tu ncua, tej zaum nws yuav yog vim cov kab hluav taws xob hauv zos tau siab dhau lawm, lub teeb taws yuav kub hnyiab, thiab cov xaim txuas tsis zoo. Thov ua tib zoo xyuas seb qhov hluav taws xob thiab cov hlau txuas ntawm lub tshuab ntsuas puas ruaj khov. Yog tias tsis yog, nws yuav yog vim lub teeb taws yuav kub hnyiab thiab lub teeb tuaj yeem hloov tau.
