Polarizing daim iav txoj kev kho polarizing microscope
Hauv kev ua haujlwm tiag tiag, cov lus qhia kev vibration ntawm lub sab sauv thiab sab polarizers ntawm lub tshuab tsom iav polarizing yuav tsum yog orthogonal rau ib leeg, lossis cov lus qhia sab hnub tuaj-sab hnub poob lossis sab qaum teb-sab qab teb, uas zoo ib yam nrog cov kab rov tav thiab ntsug ntawm cov eyepiece crosshairs feem. Qee zaum tsuas yog siv ib qho polarizer qis dua los 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, eyepiece crosshair nrhiav kom tau
Xyuas seb qhov crosshairs ntawm eyepiece yog orthogonal thiab ua raws li kev co kev taw qhia ntawm sab sauv thiab sab polarizers. Nyob rau tib lub sij hawm, xaiv ib daim ntawm biotite nrog ua tiav cleavage, txav mus rau qhov chaw ntawm lub crosshair ntawm lub eyepiece, ua rau lub cleavage seam sib npaug zos rau ib tug ntawm cov crosshairs, thiab sau cov scale naj npawb ntawm lub loading lub rooj, ces tig lub. tsiaj lub rooj ua kom lub cleavage seam sib npaug mus rau lwm yam crosshair, thiab sau cov nplai tus naj npawb ntawm lub rooj thauj khoom. Qhov sib txawv ntawm ob qhov ntsuas yog 90, qhia tias cov plaub hau yog orthogonal.
2. Kev txiav txim siab thiab kho kev co kev taw qhia ntawm qis polarizer.
Siv biotite los xyuas qhov kev vibration ntawm cov polarizer qis yog vim biotite yog cov pob tshab pob tshab, uas yog cov yam ntxwv zoo heev hauv ib qho polarization. Ua ntej, nrhiav ib daim ntawm cov ntshiab biotite nrog cleavage, txav mus rau hauv nruab nrab ntawm lub crosshair ntawm lub eyepiece, thawb tawm lub sab sauv polarizer, tig lub theem rau ib lub lim tiam, thiab soj ntsuam qhov kev hloov ntawm biotite xim. Vim tias biotite absorbs lub teeb vibration nyob rau hauv cov kev taw qhia cleavage muaj zog, thaum cov xim biotite nce mus txog * qhov tob, cov kev taw qhia ntawm cleavage seam yog cov kev vibration ntawm lub polarizer qis.
3. Kho ntawm orthogonality ntawm sab sauv thiab sab polarizers
Tom qab cov kev taw qhia ntawm lub polarizer qis dua raug kho, tshem tawm cov ntawv, thawb nws mus rau hauv lub polarizer sab saud, thiab saib seb qhov chaw pom yog dub tag los tsis yog. Yog tias nws yog tag nrho cov dub, nws txhais tau hais tias cov kev taw qhia kev co ntawm lub sab sauv thiab sab polarized lub teeb yog orthogonal rau ib leeg. Txwv tsis pub, lub sab sauv polarizer yuav tsum raug kho, uas yog, lub sab sauv polarizer yuav tsum tau tig kom pom qhov tsaus ntuj tshaj plaws. Thaum rotating, koj yuav tsum loosen lub nres ntsia hlau ntawm lub polarizer sab sauv ua ntej, thiab ces zawm nws tom qab kho.
