Yuav ua li cas kho lub polarizer ntawm polarizing microscope?
Thaum lub sijhawm ua haujlwm, cov lus qhia kev vibration ntawm sab sauv thiab sab polarizers ntawm lub tshuab ntsuas polarizing yuav tsum yog orthogonal rau ib leeg, lossis nyob rau sab hnub tuaj-sab hnub poob thiab sab qaum teb-sab qab teb, thiab yuav tsum ua raws li cov lus qhia kab rov tav thiab ntsug ntawm eyepiece crosshairs. Qee lub sij hawm tsuas yog ib qho qis polarizer yog siv rau kev soj ntsuam, thiab kev co kev taw qhia ntawm lub polarizer qis yuav tsum tau txiav txim siab, yog li cov polarizer yuav tsum tau ntsuas thaum ua haujlwm.
1. Kev txheeb xyuas qhov muag ntawm cov plaub muag crosshairs
Feem ntau, koj yuav tsum tau xyuas seb cov eyepiece crosshairs yog orthogonal thiab seb lawv puas ua raws li kev vibration ntawm sab sauv thiab sab polarizers. Nyob rau tib lub sijhawm, xaiv ib daim ntawm biotite nrog kev ua tiav heev, txav mus rau qhov nruab nrab ntawm cov eyepiece crosshairs, thiab tso cov cleavage seam mus rau ib qho ntawm cov crosshairs. xaim, sau cov lej ntawm cov nplai ntawm cov khoom theem, tom qab ntawd tig cov khoom theem kom cov cleavage seam yog sib npaug rau lwm cov plaub hau hla, sau cov nplai ntawm cov khoom theem, qhov sib txawv ntawm ob tus lej yog 90 degree. , qhia tias tus ntoo khaub lig xov hlau yog orthogonal.
2. Kev txiav txim siab thiab kho qhov kev co kev taw qhia ntawm lub polarizer qis
Biotite feem ntau yog siv los xyuas cov kev taw qhia kev vibration ntawm polarizer, vim biotite yog cov pob tshab pob tshab dav dav. Ua ntej, nrhiav ib daim ntawm biotite uas yog cleaved thiab meej, txav mus rau hauv nruab nrab ntawm lub eyepiece crosshair, thawb tawm lub sab sauv polarizer, tig lub theem rau ib tug tig, thiab soj ntsuam qhov kev hloov ntawm cov xim ntawm biotite, vim biotite muaj. lub zog nqus ntawm vibrational teeb nyob rau hauv cov kev taw qhia ntawm cleavage. Yog li ntawd, thaum cov xim ntawm biotite nce mus txog qhov tob tshaj plaws, cov kev taw qhia ntawm cov cleavage seam yog cov kev vibration ntawm lub polarizer qis.
3. Orthogonal kho ntawm sab sauv thiab sab polarizers
Tom qab kho cov kev taw qhia ntawm lub polarizer qis, tshem tawm cov ntawv, thawb rau hauv lub polarizer sab saud, thiab saib seb qhov chaw saib puas yog dub kiag li lossis nyob rau hauv lub xeev matted. 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 qhov tsaus ntuj tshaj plaws. Thaum rotating, koj yuav tsum xub loosen lub nres ntsia hlau ntawm lub sab sauv polarizer, thiab ces zawm nws tom qab kho nws.
