Broadband ar coated achromatic lo ntsiab muag
Khoom Piav Qhia
Achorratic lo ntsiab muag yog hom lo ntsiab muag uas tau tsim los txo cov teeb meem chromatic aberration, uas yog ib qho teeb meem zoo tshaj uas ua rau muaj xim zoo sib xws thaum dhau ntawm lub lens. Cov kev ntsuas no siv kev sib txuas ntawm ob lossis ntau cov khoom siv kho qhov muag uas tsis muaj qhov sib txawv ntawm lub teeb sib txawv ntawm tib qho, uas ua rau lub ntsej muag ntse ntawm lub teeb dawb. Achorratic lo ntsiab muag tau siv dav hauv ntau yam kev siv xws li yees duab, me me, lub tsom iav. Lawv pab txhawm rau txhim kho cov duab zoo los ntawm kev txo cov xim xim thiab ua kom muaj cov duab muaj tseeb thiab ntse. Lawv kuj yog siv hauv Laser tshuab thiab cov twj kho kho tshiab uas xav tau cov twj paj nruag zoo thiab pom tseeb xws li cov cuab yeej kev kho mob, thiab cov khoom siv hnub qub.
Broadband ar coated Achromatic cov ntsiab muag kho qhov muag uas muab cov kev ntsuas zoo nyob rau ntau qhov kev pom ntawm lub teeb wavelength. Cov lenses no zoo tagnrho rau ntau cov kev siv nrog kev tshawb fawb, kev kho mob kev ua haujlwm thiab kev kho mob thev naus laus zis.
Yog li dab tsi xyov yog qhov broadband ar coated Achorromatic lens? Hauv ntej, lawv tau tsim los daws cov teeb meem ntawm chromatic aberration thiab lub teeb poob uas tuaj yeem tshwm sim thaum lub teeb ci ntsa iab. Chromatic aberration yog duab distortion tshwm sim los ntawm lub lens 'ua tsis muaj peev xwm kom tsom txhua yam xim ntawm lub teeb ntawm tib qho. Achorromatic lo ntsiab muag no los ntawm kev siv ob hom iav sib txawv (feem ntau yog cov xim ntawm lub teeb ntawm tib qho, ua rau muaj cov duab ntshiab thiab ntse thiab ntse thiab ntse thiab ntse thiab ntse thiab ntse thiab ntse thiab ntse thiab ntse thiab ntse thiab ntse duab.
Tab sis Achromatic lo ntsiab muag feem ntau raug kev txom nyem los ntawm lub teeb poob vim yog qhov kev xav ntawm lub lens nto. Qhov no yog qhov broadband ar coedings los rau hauv. Ar (anti-Reflective) txheej yog ib txheej ntawm cov khoom siv uas yuav pab txo cov kev xav los ntawm lub lens. Broadband ar cov txheej txheem txhim kho ntawm cov txheej txheem txheem ntawm kev sib kis tau los ntawm kev tso cai zoo dua kis tau ntawm lub teeb dhau ntawm waverength.
Ua ke, lub lens achromatic ar txheej thiab broundband ar txheej muaj lub zog kho qhov muag uas tuaj yeem txhim kho kev ua tau zoo hauv cov ntawv thov. Lawv siv nyob rau hauv txhua yam ntawm spectrometers mus rau lub tsom iav thiab txawm tias laser tshuab. Vim yog lawv lub peev xwm los hloov cov feem pua siab ntawm lub teeb hla lub ntsej muag dav dav, cov ntsiab muag no muab cov ntse ntse, muaj kev ntsuas siab nyob hauv ib puag ncig thiab cov ntawv thov.
Broadband ar-coated oog lenses yog lub zog kho qhov muag uas tuaj yeem muab cov duab zoo tshaj qhov ntawm lub teeb wavelength. Raws li thev naus laus zis txuas ntxiv hloov zuj zus, cov lo ntsiab muag no yuav tsis muaj kev tshawb fawb txog kev tshawb fawb, kev kho mob, thiab suav tsis tau ntau yam.
