Cov yam ntxwv ntawm cov yeeb yaj kiab nyias nyias muaj xws li kev piav qhia txog cov khoom siv kho qhov muag, cov yam ntxwv kho qhov muag thiab cov khoom tsis yog kho qhov muag, cov yam ntxwv kho qhov muag feem ntau yog hais txog cov yam ntxwv ntawm kev cuam tshuam spectral, kev xa tawm thiab kev poob ntawm qhov muag (kev poob ntawm kev nqus thiab kev cuam tshuam). Kev xa tawm thiab kev cuam tshuam yog cov yam ntxwv kho qhov muag yooj yim tshaj plaws ntawm cov yeeb yaj kiab nyias nyias, yog li kev sim ntawm kev xa tawm thiab kev cuam tshuam ntawm cov yeeb yaj kiab nyias nyias yog cov txheej txheem sim yooj yim rau cov yeeb yaj kiab nyias nyias. Cov yam ntxwv kho qhov muag ntawm cov yeeb yaj kiab nyias nyias muaj xws li cov ntsuas refractive, cov coefficient nqus thiab cov tuab ntawm cov yeeb yaj kiab nyias nyias. Vim yog qhov sib txawv ntawm stoichiometric hauv cov khoom siv ntawm cov yeeb yaj kiab nyias nyias uas tau npaj los ntawm cov txheej txheem tiag tiag, cov qauv tsis yog homogeneous thiab ntom, tab sis muaj cov qauv me me thiab ntau yam tsis zoo, cov txheej txheem dielectric tsis pob tshab tag nrho, thiab muaj kev nqus tsis muaj zog, thaum muaj qhov tsis sib xws ntawm qhov chaw thiab theem anisotropy hauv cov ntsuas refractive ntawm cov yeeb yaj kiab, thiab cov yeeb yaj kiab tsis yog qhov sib txuas tsis kawg thiab du. Qhov tseem ceeb tshaj, thaum lub sijhawm npaj cov yeeb yaj kiab, cov txheej txheem npaj cov yeeb yaj kiab muaj feem cuam tshuam loj heev rau cov yam ntxwv ntawm cov yeeb yaj kiab, yog li qhov kev lees paub tiag tiag ntawm cov yam ntxwv ntawm cov yeeb yaj kiab yog qhov tseem ceeb heev. Tsis tas li ntawd, cov yeeb yaj kiab nyias nyias ua lub cuab yeej siv hauv qhov chaw ib puag ncig tiag tiag, ntxiv rau cov yam ntxwv ntawm cov cuab yeej yuav tsum ua kom tau raws li qhov yuav tsum tau ua, cov yeeb yaj kiab muaj ntau lwm yam tseem ceeb uas tsis yog-optical cuam tshuam rau kev siv cov yeeb yaj kiab, xws li kev nplaum cov yeeb yaj kiab, kev ntxhov siab ntawm cov yeeb yaj kiab, qhov nyuaj ntawm cov yeeb yaj kiab thiab qhov roughness ntawm qhov chaw thiab cov yeeb yaj kiab lub peev xwm tiv taus ib puag ncig thiab lwm yam. Yog li ntawd, nws yog ib qho tseem ceeb kom ntsuas txhua yam kev ntsuas lossis cov yam ntxwv uas cuam tshuam rau kev siv cov khoom siv nyias nyias.
Kev xa tawm thiab kev cuam tshuam ntawm cov yeeb yaj kiab nyias feem ntau yog sim siv cov khoom siv ntsuas spectral. Cov khoom siv ntsuas spectral rau kev kuaj yeeb yaj kiab kho qhov muag tuaj yeem muab faib ua UV-Vis spectrophotometers, infrared spectrophotometers thiab infrared Fourier spectrometers raws li cov kab sib txawv. Ob qho thawj zaug siv cov hauv paus ntsiab lus ntawm kev tshuaj xyuas thiab kev sim system, qhov tom kawg raws li lub hauv paus ntsiab lus ntawm kev cuam tshuam spectral analysis system. Vim yog cov qauv geometric sib txawv thiab cov duab ntawm cov khoom siv nyias-zaj duab xis, txawm hais tias txhua qhov kev ntsuas transmittance thiab kev cuam tshuam, tab sis rau cov duab sib txawv, qhov tseeb sib txawv lossis cov kev xav tau polarization sib txawv, yuav xav tau cov txheej txheem xeem sib txawv thiab cov txheej txheem.
