Raman spectroscopy yog ib qho kev tshuaj ntsuam xyuas siv los txheeb xyuas thiab txheeb xyuas cov tshuaj muaj pes tsawg leeg thiab cov qauv ntawm cov qauv los ntawm kev tsom xam ntawm cov teeb tawg.
Wavelength - Lub zog ntawm Raman teeb liab yog ncaj qha nyob ntawm lub wavelength ntawm lub laser qhov chaw, qhov twg cov wavelengths qis dua yuav tsim muaj zog Raman signals, nrog rau kev tso cai rau ntau dua spatial daws teeb meem. Nws yog ib qho tseem ceeb, txawm li cas los xij, kom sib npaug qhov kev soj ntsuam no nrog qhov tshwm sim ntawm keeb kwm yav dhau fluorescence, muaj ntau yam khoom siv thoob plaws hauv UV-pom pom spectrum, thiab muaj peev xwm ntawm cov qauv kev puas tsuaj ntawm lub zog siab. Cov teebmeem no feem ntau ua rau muaj kev cuam tshuam hauv lub wavelength ntawm qhov siv, qhov ntev wavelengths, xws li 532 nm, 785 nm, thiab 1064 nm, ua ke nrog cov cuab yeej rhiab heev, tso cai rau qhov dav tshaj plaws ntawm cov qauv ntsuas.
Spectral Linewidth & Purity - Lub spectral linewidth ntawm lub laser qhov chaw yuav tsum tau txiav txim siab, raws li nws yuav txwv qhov kev daws teeb meem ntawm Raman ntsuas nrog rau qhov tsawg kawg nkaus lub zog hloov uas tuaj yeem txiav txim siab. Nws yog ib qho tseem ceeb rau lub laser xaiv kom muaj ib tug linewidth hauv qab no tag nrho cov kev daws teeb meem ntawm Raman spectrometer, ntawm qhov kev txiav txim ntawm picometers. Rau high-resolution spectroscopy, qhov no yog ib qho tseem ceeb thiab yuav tsum tau linewidths hauv qab no 1 MHz. High spectral purity kuj yuav ua rau kom lub teeb liab-rau-suab nrov piv los ntawm kev ntsuas.
Beam Quality - Lub beam zoo muaj feem xyuam rau qhov kev daws teeb meem spatial. Ntawm no, ib qho kev sib hloov kab teeb (TEM00) yog qhov tseem ceeb rau kev sib txuas lus Raman Spectroscopy, tshwj xeeb, tso cai rau kev tswj xyuas qhov siab hauv txhua qhov peb axes, txhim kho qhov kev daws teeb meem, thiab txo cov teebmeem tom qab.
