Optical Narrow Bandpass Lim 450nm Rau Optical Coherence Tomography

Ib qho optical nqaim bandpass lim 450nm yog cov cuab yeej tshwj xeeb uas tso cai rau tsuas yog ib qho kev txwv ntawm wavelengths nyob ib ncig ntawm 450 nanometers (nm) kom dhau mus. Nws ua haujlwm los ntawm kev xaiv lim tawm cov tsis xav tau wavelengths thaum xa cov kev xav tau ntawm wavelengths, ua rau nws muaj txiaj ntsig zoo hauv ntau daim ntawv thov xws li fluorescence microscopy, qhov twg cov wavelengths tshwj xeeb ntawm lub teeb yuav tsum tau ua kom muaj zog fluorescent molecules, lossis hauv colorimetry, qhov twg yuav tsum muaj kev ntxub ntxaug xim.

 

UVWAVETEK muaj qhov zoo-ua pov thawj 450nm cov ntxaij lim dej kho qhov muag nrog cov qib kis tau tus mob siab thiab huv thiab raug spectral tso zis teeb liab. Cov ntxaij lim dej yog tsim los ntawm cov khoom siv kho qhov muag zoo kom txo qis kev cuam tshuam, tawg, thiab lwm yam khoom siv kho qhov muag uas tuaj yeem cuam tshuam qhov zoo ntawm cov teeb liab tso tawm. Dab tsi ntxiv, lawv muaj zog thiab ruaj khov txaus los tiv thaiv ib puag ncig ntawm daim ntawv thov. Tiv tauj peb hnub no los xaiv cov lim zoo tshaj plaws rau koj qhov kev thov tshwj xeeb!

450nm bandpass lim siv li cas hauv optical coherence tomography (OCT)?

Optical coherence tomography (OCT) yog cov txheej txheem uas tsis muaj kev cuam tshuam uas siv lub teeb nthwv dej los ua kom muaj kev daws teeb meem siab, cov duab hla ntawm cov ntaub so ntswg. Optical nqaim bandpass lim 450nm feem ntau yog siv hauv OCT systems los cais cov wavelength tshwj xeeb ntawm lub teeb siv rau kev kos duab.

 

Hauv OCT, lub teeb pom kev sib txuas qis ua rau pom cov ntaub so ntswg uas tau pom, thiab lub teeb rov qab raug kuaj pom thiab tshuaj xyuas. Cov teeb liab pom tau tsim ib daim duab peb-dimensional daim duab.

 

Txhawm rau tsim cov duab zoo, siv qhov nqaim bandwidth teeb pom kev zoo uas muab lub siab axial daws teeb meem yog qhov tseem ceeb. Nqaim bandpass lim lim tawm qhov tsis xav tau wavelengths thiab muab lub teeb pom kev tsis zoo ntawm bandwidth, tso cai rau cov duab meej ntawm cov ntaub so ntswg.

 

Ntxiv mus, 450nm wavelength feem ntau yog siv hauv OCT duab vim nws tau nqus los ntawm qee cov xim, xws li melanin, tso cai rau kev txhim kho cov duab ntawm cov ntaub so ntswg uas muaj cov xim no. Tsis tas li ntawd, 450nm wavelength tsis tawg los ntawm cov ntaub so ntswg ntau dua qhov ntev wavelengths, ua rau muaj teeb meem tsawg dua thiab txhim kho qhov tob tob.

 

Nqaim bandpass lim ntawm 450nm kuj tseem siv rau hauv spectral domain OCT (SD-OCT) systems, uas cais cov kab tshwj xeeb thiab muab cov kev daws teeb meem siab. Cov ntxaij lim dej no tso cai rau kev txheeb xyuas cov qauv ntawm cov ntaub so ntswg thiab tuaj yeem muab cov ntaub ntawv ntxiv, xws li cov ntaub so ntswg muaj pes tsawg leeg thiab kev ua haujlwm metabolic.
