IR Dichroic Daim iav IR Dichroic Filter

Infrared dichroic iav yog cov lim tshwj xeeb uas cais lub teeb infrared los ntawm pom lub teeb. Lawv siv qhov sib txawv ntawm cov wavelengths, xav txog IR thaum hla cov hluav taws xob pom. Cov "kub iav" no yog ua los ntawm ultra-thin film coatings ntawm iav engineered los cuam tshuam thiab cuam tshuam cov IR bands. Dichroic tsom iav ua rau kev coj ncaj lossis sib cais ntawm cov kab hluav taws xob infrared hauv laser tshuab. Lawv tau siv nyob rau hauv microscopes tso cai rau lub teeb excitation thaum xav txog IR emission los ntawm cov qauv fluorescent. IR koob yees duab siv iav kub los lim tawm lub teeb pom kev. Cov kws yees duab ntiav lawv kom hloov IR deb ntawm cov sensors. Nrog rau qhov tseeb wavelength cut-offs, infrared dichroic tsom iav yog qhov tseem ceeb rau kev tswj thiab tswj lub teeb infrared hla ntau qhov chaw.

 

Peb cov iav infrared dichroic muab precision tswj lub teeb infrared rau koj xav tau. Siv multilayer optical coatings ntawm iav, peb cov iav kub tsom xam cov infrared bands thaum xa cov teeb pom kev zoo. High IR reflectance thiab ntse txiav-on / tawm wavelengths xa cov spectral pom zoo los ntawm 700nm txog 20μm. Tsis tshua muaj kev sib cais ntawm IR thiab qhov muag pom ua rau lawv zoo tagnrho rau kev coj cov IR lasers, lim cov tshuab ntsuas hluav taws xob, tiv thaiv sensors los ntawm IR, thiab ntau dua. Ua ke nrog peb ntau yam ntawm pom dichroics thiab ntug lim, peb engineer customized infrared dichroics nrog optimized kev ua tau zoo. Rau siab heev IR teeb manipulation, cia siab rau peb cov iav dichroic tsim rau koj cov kev thov tshwj xeeb.

Dab tsi yog daim iav dichroic?

Daim iav dichroic muaj ntau txheej nyias nyias ntawm cov txheej tshwj xeeb ntawm cov iav substrate. Cov iav, feem ntau yog cov khoom siv kho qhov muag zoo li BK7, muab kev txhawb nqa txhua yam thiab lub ntsej muag du rau cov txheej txheem kom muab tso rau. Cov txheej txheej nyias nyias yog tus yuam sij los tsim cov nyhuv dichroic. Lawv muaj cov txheej txheem sib hloov ntawm cov ntaub ntawv uas muaj qhov ntsuas siab thiab qis qis, xws li zinc sulfide thiab thorium fluoride. Txhua txheej muaj ib tug precisely tswj thickness ntawm kaum mus rau pua pua nanometers.

 

Cov txheej no tau tso los ntawm cov txheej txheem nqus xws li thermal evaporation lossis magnetron sputtering, uas tso cai rau cov txheej txheem kho qhov muag zoo tsuas yog ob peb lub atoms tuab kom muab tso rau. Nyob ntawm daim iav tsim, kaum ob ntawm cov pob tshab no tau tsim los ua kom tag nrho cov pawg dichroic, nyob qhov twg los ntawm 10 mus rau 100 txheej. Cov kev sib tshuam ntawm cov txheej txheem refractive index txheej tsim kev cuam tshuam uas xaiv los yog xa cov wavelengths sib txawv ntawm lub teeb.

 

Los ntawm kev kho lub thickness ntawm cov khaubncaws sab nraud povtseg nyob rau hauv pawg, lub wavelength bands uas yog reflected los yog kis tau yuav engineered nrog zoo yooj. Cov khaubncaws sab nraud povtseg muaj graded thickness profiles es tsis yog cov kauj ruam discrete, tso cai rau kev hloov chaw ntawm lub reflection thiab kis cheeb tsam. Cov txheej tiv thaiv kev cuam tshuam kuj tseem tuaj yeem ntxiv rau sab kis lub teeb kom txo qis qhov tsis pom kev pom. Cov txheej saum toj kawg nkaus yog txheej txheej tiv thaiv uas tiv thaiv pawg tiv thaiv ib puag ncig thiab kev puas tsuaj. Thaum tsim tau meej lawm, cov txheej txheej multilayer interferometric muab lub dichroic daim iav lub peev xwm los xaiv cov teeb pom kev zoo infrared thaum xa cov teeb pom kev hauv cov khoom tawg yooj yim, ruaj khov kho qhov muag.
