Yuav ua li cas paub qhov txawv ntawm stereomicroscope thiab metallographic microscope
Teeb pom kev zoo system
1. Metallographic microscopes feem ntau muaj ib txoj hauv kev zoo rau lub teeb pom kev zoo (vim cov qauv pom yog opaque), thiab lub teeb pom kev zoo dhau los ntawm lub lens semi reflective thiab ces irradiated rau saum npoo ntawm cov qauv los ntawm lub hom phiaj lens. Tom qab rov qab xav txog, nws dhau los ntawm lub hom phiaj lens thiab lub qhov muag ua ntej yuav pom hauv tib neeg lub qhov muag. Yog li ntawd, lub hom phiaj lens hloov lub condenser lens hauv Kohler illumination system. Nyob rau hauv txoj cai, hom teeb pom kev zoo no belongs rau coaxial teeb pom kev zoo, qhov twg lub teeb pom kev zoo thiab cov teeb pom kev zoo nyob hauv tib txoj kev kho qhov muag.
2. Stereoscopic microscopes feem ntau siv cov teeb pom kev sab nraud, suav nrog cov teeb halogen rau oblique teeb pom kev zoo thiab cov teeb ci LED ncig rau illumination. Txawm li cas los xij, cov kev teeb pom kev zoo no tsis yog coaxial illumination, thiab lawv cov illumination yog oblique los ntawm sab, nrog rau qee lub kaum ntse ntse nrog lub ntsiab kho qhov muag. Raws li txoj cai, lawv zoo ib yam li qhov tsaus ntuj illumination ntawm metallographic microscopes. Tsis tas li ntawd, qee qhov stereomicroscopes kuj muaj cov teeb pom kev zoo coaxial, tab sis coaxial teeb pom kev zoo hauv stereomicroscopes muaj qee qhov kev txwv. Kev tsim tsis zoo tuaj yeem ua rau lub ntsej muag, uas yuav tsum tau ntxiv cov khoom siv tshwj xeeb lossis lo ntsiab muag kom tshem tawm nws.
Magnification factor
1. Qhov loj ntawm lub hom phiaj lens ntawm lub tshuab ntsuas metallographic yog siab dua 1.25 npaug thiab qis dua 100 zaug, thaum qhov loj ntawm lub qhov muag yog nyob nruab nrab ntawm 10X thiab 20X. Yog li ntawd, tag nrho cov magnification ntawm lub tshuab ntsuas metallographic yog nyob nruab nrab ntawm 12.5 thiab 2000 zaug.
2. Qhov txawv ntawm magnification ntawm lub tso suab microscope yog heev loj. Yog tias nws yog ib qho tshuaj ntsuam xyuas lub tso suab tso suab tsis tu ncua, qhov kev nthuav dav yog feem ntau ntawm 0.5 thiab 100 zaus. Yog tias nws yog qib tshawb fawb lub tshuab tsom, thaum txhim kho qhov muag pom kev zoo, qhov kev nthuav dav kuj tseem yuav nce mus txog 200 txog 400 zaug
Khib thiab tsom mechanism
1. Lub thav duab ntawm lub tshuab ntsuas metallographic feem ntau yog qhov loj, tab sis vim nws yog siv rau kev tshuaj xyuas lub zog siab, nws tuaj yeem tso cov qauv nrog qhov me me. Feem ntau, cov qauv saum npoo yuav tsum tau tiaj tus, thiab cov qauv kev npaj, polishing, thiab corrosion yuav tsum tau. Nyob rau hauv no hais txog, tsuas yog inverted metallographic microscopes, txawm hais tias tus qauv npaj kuj yuav tsum tau, nws yuav luag tsis muaj kev txwv rau qhov loj ntawm cov qauv. Ib qho zoo inverted metallographic microscope tuaj yeem tso cov qauv uas hnyav li 10 kilograms. Tsis tas li ntawd, lub tsom xam mechanism ntawm upright metallographic microscope yog ib theem lifting (tseem muaj ob peb upright microscopes thiab ntsuas microscopes uas siv tshwj xeeb attachments nqa lub hom phiaj), thaum lub inverted metallographic tsom mechanism yog lub hom phiaj nqa.
2. Lub thav duab loj ntawm lub stereo microscope feem ntau yog me me, tab sis yog tias ua ke nrog ib qho loj-loj txav thav duab, nws tuaj yeem tshawb xyuas cov qauv ntawm ntau qhov sib txawv, suav nrog ncaj qha tshuaj xyuas cov khoom ntawm cov kab ntau lawm. Yog li ntawd, nws muaj qhov xav tau qis rau cov qauv thiab tsis xav tau cov qauv tshwj xeeb npaj. Tsuav tus qauv saum npoo yog roughly tiaj, nws txaus. Vim hais tias stereoscopes kuj yog lub teeb, txoj kev tsom ntawm stereomicroscopes feem ntau yog nqa thiab txo tag nrho txoj kev kho qhov muag ntawm tus tswv tsev.
