785nm Holographic Notch Lim Rau Raman Spectroscopy

Holographic notch filters yog cov ntxaij lim dej kho qhov muag uas xaiv xa lub teeb nyob rau hauv ib qho tshwj xeeb wavelength ntau yam thaum thaiv qhov seem. Cov ntxaij lim dej no siv cov txheej txheem sau cia holographic los tsim cov qauv ntu ntawm cov iav substrate, uas ua rau muaj kev cuam tshuam kev cuam tshuam ntawm qhov tsis xav tau wavelengths.

Lub 785nm holographic notch lim thaiv lub teeb laser ntawm 785nm wavelength ntau. Nws yog feem ntau siv hauv Raman spectroscopy los nres Rayleigh tawg ntawm lub teeb laser thiab txhim kho Raman spectra lub teeb liab-rau-nruab piv.

UVWAVETEK yog cov chaw tsim khoom lag luam ntawm cov ntxaij lim dej uas ua tau zoo 785nm cov ntxaij lim dej thoob ntiaj teb. Cov lim dej muaj txiaj ntsig zoo thiab muaj qhov sib kis tau zoo txog li 90 feem pua ​​​​rau qhov xav tau wavelength. Nws kuj tseem ruaj khov thiab tiv taus qhov kub thiab txias, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau txhua qhov chaw kuaj lossis chaw tsim khoom.

Daim ntawv thov

Lub 785nm holographic optical notch lim feem ntau yog siv hauv Raman spectroscopy los thaiv Rayleigh tawg ntawm lub teeb laser thiab txhim kho Raman spectra lub teeb liab-rau-suab nrov piv. Nws yog ib qho tseem ceeb nyob rau hauv Raman spectroscopy daim ntaub ntawv uas yuav tsum tau xaiv kis tau tus mob ntawm lub teeb nyob rau hauv ib tug tshwj xeeb wavelength ntau yam thaum thaiv tus so.

Keeb kwm kev loj hlob ntawm Raman spectroscopy

Raman spectroscopy tau tshawb pom los ntawm Indian physicist Sir Chandrasekhara Venkata Raman hauv xyoo 1928. Nws pom tias ib feem me me ntawm lub teeb tau tawg mus rau ntau qhov kev taw qhia thaum lub teeb ci rau ntawm cov khoom siv. Lub teeb tawg tawg tuaj yeem hloov lub wavelength, uas yog hu ua Raman nyhuv. Cov nyhuv no tuaj yeem siv los txheeb xyuas cov tshuaj muaj pes tsawg leeg ntawm cov khoom siv. Raman spectroscopy tau dhau los ua cov cuab yeej tseem ceeb hauv chemistry, physics, biology, thiab cov ntaub ntawv tshawb fawb.

Txij li thaum nws tshawb pom, Raman spectroscopy tau dhau los ua qhov tseem ceeb. Nyob rau xyoo 1960, qhov kev tsim kho ntawm lub laser tau txhim kho qhov rhiab heev thiab kev daws teeb meem ntawm Raman spectroscopy. Nyob rau xyoo 1970, resonance Raman spectroscopy tau tsim, tso cai rau kev kawm ntawm cov molecules 'zoo siab rau hluav taws xob xeev. Nyob rau xyoo 1980, qhov chaw ua kom zoo nkauj Raman spectroscopy (SERS) tau tshawb pom, uas ua rau muaj kev nkag siab zoo ntawm Raman spectroscopy los ntawm ntau qhov kev txiav txim loj.

Niaj hnub no, Raman spectroscopy yog cov txheej txheem siv dav hauv ntau yam kev tshawb fawb thiab thev naus laus zis. Nws yog siv nyob rau hauv kev lag luam kws tshuaj los soj ntsuam cov purity ntawm cov tshuaj, nyob rau hauv forensic science los txheeb xyuas cov ntaub ntawv pov thawj, thiab nyob rau hauv nanotechnology los kawm nanoparticles 'cov khoom. Txoj kev loj hlob ntawm Raman spectroscopy siv 785nm holographic notch lim tau ua rau peb nkag siab txog cov khoom siv lub cev thiab tshuaj lom neeg thiab tau taug kev rau ntau yam kev nce qib hauv kev tshawb fawb thiab thev naus laus zis.
