KhoomAbstract
Spectrometers yog cov cuab yeej tseem ceeb hauv kev tshawb fawb niaj hnub thiab kev lag luam.Txhawm rau nthuav dav lawv cov kev siv ntau yam, cov kws tshawb fawb tau thov kom muaj dual-channel spectrometer uas suav nrog yim subgratings, hloov cov khoom siv txav mus los siv hauv cov qauv tsim.Ob txheej ntawm quadrifold spectra yog siv rau diffraction thiab imaging nyob rau hauv lub sab sauv thiab sab focal dav hlau ntawm Dhyana 90A lub koob yees duab, ntsig txog.Lub quantum efficiency ntawm lub koob yees duab ntawm 400nm yog hais txog 90%.Ntxiv nrog rau qhov txiaj ntsig zoo ntawm cov khoom siv spectroscopic, cov qauv tsim ntawm lub spectrometer ua rau kev ntsuas ib txhij ntawm ntau qhov spectro.
Daim duab 1 Schematic illustration ntawm lub spectrometer system.(a) S1 thiab S2 yog ob qho tib si optical slits.G1 thiab G2 yog ob pawg ntawm gratings, txhua tus muaj 4 sub-gratings.Cov kab 4-folded spectral los ntawm G1 thiab G2 yog duab nrog cov kev daws teeb meem siab nyob rau sab sauv thiab qis, feem, ntawm lub dav hlau focal ntawm BSI-CMOS array ntes.(b) Ib txheej ntawm cov khoom siv kho qhov muag (S1, G1, iav 1 thiab 2, thiab lim teeb F) tau teeb tsa xws li cov kab spectral ntawm channel 1 yog duab nyob rau sab sauv ntawm lub dav hlau focal ntawm BSI-CMOS ntes D . Cov haujlwm grey-xim pom hauv F1 thiab F2 hauv (a) yog qhov khoob (tsis muaj lim)

Kev tsom xam ntawm kev siv technology
Txawm li cas los xij, spectrometers yuav tsum ntsuas ntau tshaj ib lub teeb pom kev nyob rau tib lub sijhawm hauv qee qhov xwm txheej, Kev ntsuas ntsuas qhov sib txawv hauv lub sijhawm sib txawv yuav raug kev txom nyem los ntawm lub sijhawm cuam tshuam los yog yuam kev cuam tshuam los ntawm kev hloov lub teeb.Thiab nws yog ib qho nyuaj rau siv cov cuab yeej sib txawv kom paub txog tib lub quantum efficiency nrog rau ib puag ncig sib txawv.Yog li ntawd, txhawm rau kov yeej cov teeb meem no, cov kws tshawb fawb kawm txog qhov tshiab compact spectrometer uas yog raws li Dhyana 90A.Lub Dhyana 90A nta dav spectral ntau (200-950 nm nrhiav wavelength), tus ncej siab (24 ntas ib ob), siab daws teeb meem (zoo dua 0.1nm / pixel), thiab 16-ntsis siab dynamic ntau yam.Qhov no siv ob-dimensional BSI-CMOS array detector sib koom los ntawm ntau lub spectral channel vam tias yuav sawv cev rau yav tom ntej qauv ntawm kev loj hlob spectrometer.
