Osram Qhia Ze-infrared LED rau Spectroscopy Applications, Pab Saib Xyuas Khoom Noj Zoo

Puas yog lub tsho ntawm lub txee tiag tiag tsim los ntawm 100% paj rwb? Puas yog cov kua txiv hmab txiv ntoo hauv lub khw muag khoom puas tsuaj thiab tsis muaj vitamin, lossis nws tsuas zoo li qab? Cov lus teb rau cov lus nug no tuaj yeem tau txais los ntawm kev kuaj xyuas ntau dua ntawm cov qauv molecular. Qhov no yog yooj yim los ntawm ze-infrared spectroscopy. Tau ntau xyoo, Osram Opto Semiconductors tau koom nrog hauv kev tsim cov broadband infrared LEDs uas yog ob qho tib si compact thiab muaj zog tshwj xeeb, nrog rau kev tsom mus rau spectroscopy. Qhov loj me me thiab lub zog ua haujlwm ntawm cov khoom sib xyaw ua ke yog qhov tseem ceeb rau cov tuam txhab tsim khoom, ntxiv rau qhov dav wavelength ntau yam. Osram's Oslon P1616 SFH 4737 integrates cov cwj pwm no thiab muab cov neeg siv khoom muaj txiaj ntsig ntxiv. Cov kev daws teeb meem txawb spectroscopy sai sai yuav dhau los ua qhov tseeb raws li qhov tshwm sim ntawm cov khoom no.
Qhov tseem ceeb tshaj plaws ntawm infrared lub teeb qhov chaw rau ze-infrared spectroscopy yog encompass ib tug dav spectrum ntawm wavelengths nyob rau hauv lub emitted lub teeb. Qhov ntau dua, qhov ntau dua ntawm cov khoom uas tuaj yeem txheeb xyuas tau. Lub hom phiaj khoom yog suffused nrog lub teeb infrared ntawm ib tug dav wavelength ntau yam (feem ntau 650 mus rau 1050 nanometers) kom paub meej cov dej los yog cov khoom. Qee lub teeb no yog absorbed, thaum lwm tus yog reflected. Cov ntiv tes molecular ntawm txhua yam yog qhov txawv vim qhov tseeb tias qhov piv txwv no txawv ntawm qhov khoom mus rau qhov khoom. Ib tug tshwj xeeb detector yog ua hauj lwm los ntes lub reflected lub teeb. Cov ntaub ntawv no yog tom qab ua tiav los ntawm software, uas muab piv rau cov ntaub ntawv sau tseg hauv huab thiab tom qab ntawd tsim cov txiaj ntsig ntsuas.


Osram's Oslon P1616 SFH 4737, uas lub tuam txhab lees paub yog lub ntiaj teb qhov tsawg tshaj plaws nyob ze-infrared LED (NIRED) rau kev siv spectroscopy hauv khw, muaj qhov ntev ntawm 1.6mm x 1.6mm x 0.9mm. Nws yog haum rau siv nyob rau hauv portable pab kiag li lawm. Nws kuj tseem tsim cov zis ntawm 74mW ntawm 350mA, uas yog kwv yees li peb npaug ntawm qhov txiaj ntsig ntawm cov khoom dhau los. Tsis tas li ntawd, cov khoom tshiab muab ob npaug rau qhov txiaj ntsig ntawm yav dhau los Osram NIREDs los ntawm kev muab kev siv hluav taws xob nyob rau pem hauv ntej ntawm 18mW / sr.
Cov tshuaj tiv thaiv hais txog qhov teeb meem ntawm silicon-based detectors, uas feem ntau muaj kev txo qis hauv qhov rhiab heev thaum lub wavelength nce, tshwj xeeb tshaj yog saum 950 nanometers, los ntawm kev sib koom ua ke tshiab phosphor thev naus laus zis kom tawm lub teeb ntau dua ntawm cov wavelengths siab dua.


"Peb cov NIREDs tau ua haujlwm nyob rau hauv daim ntawv thov mobile spectroscopy los txheeb xyuas cov tshuaj cuav thiab cov ntawv sau nyiaj, ntxiv rau kev txiav txim siab cov zaub mov tshiab." "Hauv kev ua liaj ua teb, lawv yog cov cuab yeej tseem ceeb rau kev txiav txim siab lub sij hawm sau qoob loo zoo," hais Carola Diez, Tus Thawj Saib Xyuas Khoom Muag ntawm Osram Opto Semiconductors.
