Nyob rau hauv feem ntau spectrometers, lub divergent lub teeb yog ces collimated los ntawm ib tug concave daim iav thiab coj mus rau ib tug grating… uas yog tom qab ntawd tsom los ntawm daim iav thib ob concave thiab muab tso rau hauv lub ntes.
Diffraction grating spectrometer ua haujlwm li cas?
Ib diffraction grating yog ib qho khoom siv kho qhov muag, uas sib cais (disperses) polychromatic lub teeb rau hauv nws cov ntsiab lus wavelengths (xim) Cov teeb meem polychromatic ntawm lub grating yog dispersed kom txhua lub wavelength yog reflected los ntawm lub grating ntawm ib tug me ntsis txawv lub kaum sab xis.
Lub hauv paus ntsiab lus ntawm kev sim spectrometer siv grating yog dab tsi?
Basic Function of Spectrometers
Lub qhov vignettes lub teeb thaum nws nkag mus rau lub spectrometer. Tom qab ntawd, nyob rau hauv feem ntau spectrometers, lub teeb sib txawv yog collimated los ntawm ib daim iav concave thiab coj mus rau ib tug gratingTom qab no, lub grating disperses lub spectral Cheebtsam ntawm lub teeb ntawm me ntsis txawv cov ces kaum.
grating spectrometer yog dab tsi?
Ib qho cuab yeej uas siv lub diffraction grating kom disperse lub teeb rau hauv ib lub spectrum. Gratings yuav muab tso rau ntawm lub tsom iav raj (lub focal-plane spectrometer) los yog nyob rau hauv pem hauv ntej ntawm lub tsom iav raj (lub hom phiaj spectrometer). Grating spectrometers yog siv rau spectroscopy ntawm wavelengths los ntawm X-rays mus rau deb infrared.
Kev ua haujlwm ntawm grating hauv spectrophotometer yog dab tsi?
Qhov kev sib txawv ntawm lub spectrometer txiav txim siab lub wavelength ntau yam thiab ib nrab txiav txim siab qhov kev daws teeb meem kho qhov muag uas lub spectrometer yuav ua tiavXaiv qhov raug grating yog qhov tseem ceeb hauv kev ua kom koj lub spectrometer zoo rau qhov zoo tshaj plaws spectral tshwm sim hauv koj daim ntawv thov.
