Yuav ua li cas calibrate lub polarizer ntawm polarizing microscope?
Hauv kev ua haujlwm, cov lus qhia kev vibration ntawm sab sauv thiab sab polarizers ntawm polarizing microscope yuav tsum yog nyob rau ib leeg, lossis cov lus qhia sab hnub tuaj-sab hnub poob thiab sab qaum teb-sab qab teb, uas muaj feem cuam tshuam nrog cov kab rov tav thiab ntsug ntawm cov eyepiece reticle. Qee lub sij hawm tsuas yog ib qho qis polarizer yog siv rau kev soj ntsuam, thiab kev co kev taw qhia ntawm cov polarizer qis yuav tsum tau txiav txim siab, yog li cov polarizer yuav tsum tau kho thaum lub sijhawm ua haujlwm.
1. Kev kuaj pom ntawm qhov muag pom reticle
Feem ntau, nws yog ib qho tsim nyog los xyuas seb lub eyepiece reticle yog orthogonal thiab seb nws puas yog nyob rau hauv tib lub vibration kev taw qhia raws li lub sab sauv thiab sab polarizers. Nyob rau tib lub sijhawm, xaiv ib daim ntawm biotite uas tau muab tshem tawm tag, txav mus rau qhov chaw ntawm lub qhov muag ntawm qhov muag, thiab muab cov cleavage seam sib npaug rau ib qho ntawm cov reticle. sau cov nplai tus naj npawb ntawm theem, thiab tom qab ntawd tig rau theem kom lub cleavage seam yog sib npaug mus rau lwm yam ntoo khaub lig xaim, sau cov nplai tus lej ntawm theem, qhov sib txawv ntawm ob tus lej ntsuas yog 90 degree, qhia tias tus ntoo khaub lig xaim. yog orthogonal.
2. Kev txiav txim siab thiab kho qhov kev co kev taw qhia ntawm lub polarizer qis
Feem ntau, biotite yog siv los xyuas cov kev taw qhia kev vibration ntawm polarizer, vim biotite yog cov pob tshab pob tshab dav dav. Ua ntej pom ib daim ntawm cleaved thiab ntshiab biotite, txav mus rau hauv nruab nrab ntawm lub reticle ntawm lub qhov muag, thawb tawm lub sab sauv polarizer, tig lub theem rau ib lub voj voog, thiab saib xyuas cov xim hloov ntawm biotite, vim biotite muaj lub zog nqus ntawm cov khoom. Kev vibration lub teeb nyob rau hauv cov kev taw qhia cleavage, Yog li ntawd, thaum cov xim ntawm biotite mus txog qhov tob tshaj plaws, cov kev taw qhia ntawm lub cleavage seam yog kev co kev taw qhia ntawm sab polarizer.
3. Orthogonal kho ntawm sab sauv thiab sab polarizers
Tom qab cov kev taw qhia ntawm lub polarizer qis yog calibrated, tshem tawm daim ntawv, thawb lub polarizer sab sauv nyob rau hauv, thiab saib seb lub teb ntawm saib yog tag nrho dub los yog tsis. Yog tias nws yog dub kiag li, nws txhais tau hais tias cov kev taw qhia kev co ntawm lub sab sauv thiab sab polarized teeb yog orthogonal rau ib leeg. Txwv tsis pub, lub sab sauv polarizer yuav tsum raug kho kom qhov chaw pom mus txog qhov tsaus ntuj tshaj plaws. Thaum tig, nres ntsia hlau ntawm lub polarizer sab sauv yuav tsum tau xoob ua ntej, thiab tom qab ntawd nruj nreem kaw tom qab calibration.
