Broadband AR Coated Achromatic Lenses
Product Description
Achromatic lo ntsiab muag yog hom lo ntsiab muag uas tsim los txo qis chromatic aberration, uas yog ib qho teeb meem kho qhov muag uas ua rau cov xim sib txawv thaum hla lub lens. Cov lo ntsiab muag no siv kev sib xyaw ntawm ob lossis ntau cov khoom siv kho qhov muag nrog qhov sib txawv refractive indices los tsom qhov sib txawv wavelengths ntawm lub teeb nyob rau tib lub ntsiab lus, uas ua rau lub ntse ntse ntawm lub teeb dawb. Achromatic lo ntsiab muag yog dav siv nyob rau hauv ntau yam kev siv xws li kev yees duab, microscopy, telescopes, thiab binoculars. Lawv pab txhim kho cov duab zoo los ntawm kev txo cov xim fringes thiab tsim cov duab zoo dua thiab ntse. Lawv kuj tau siv dav hauv cov tshuab laser thiab cov cuab yeej kho qhov muag uas yuav tsum tau muaj qhov tseeb thiab meej xws li cov cuab yeej kho mob, spectrometers, thiab cov cuab yeej siv hnub qub.
Broadband AR Coated Achromatic Lenses yog cov khoom siv kho qhov muag uas muaj peev xwm ua tau zoo tshaj plaws ntawm ntau lub teeb wavelengths. Cov lo ntsiab muag no zoo tagnrho rau ntau yam kev siv suav nrog kev tshawb fawb tshawb fawb, kev kho mob duab thiab thev naus laus zis thev naus laus zis.
Yog li dab tsi yog qhov broadband AR coated achromatic lens? Hauv luv luv, lawv tau tsim los daws cov teeb meem ntawm chromatic aberration thiab lub teeb poob uas tuaj yeem tshwm sim thaum lub teeb yog refracted los ntawm ib txwm lo ntsiab muag. Chromatic aberration yog cov duab distortion tshwm sim los ntawm lub lens 'tsis muaj peev xwm tsom tag nrho cov xim ntawm lub teeb ntawm tib qho chaw. Achromatic lo ntsiab muag daws qhov teeb meem no los ntawm kev siv ob hom iav (feem ntau yog cov iav iav thiab flint iav) los tsim ib lub lens uas tuaj yeem tsom txhua xim ntawm lub teeb ntawm tib lub ntsiab lus, ua rau cov duab meej thiab ntse.
Tab sis achromatic lo ntsiab muag feem ntau raug kev txom nyem los ntawm lub teeb poob vim qhov kev xav ntawm lub lens nto. Qhov no yog qhov broadband AR coatings tuaj rau hauv. AR (anti-reflective) txheej yog txheej nyias ntawm cov khoom siv rau saum npoo ntawm lub lens uas pab txo qhov kev xav thiab ua kom lub teeb kis tau los ntawm lub lens. Broadband AR coatings txhim kho ntawm cov txheej txheem AR txheej los ntawm kev tso cai rau kev sib kis tau zoo ntawm lub teeb hla ntau qhov dav ntawm wavelengths.
Ua ke, achromatic lens thiab broadband AR txheej muab lub zog kho qhov muag uas tuaj yeem txhim kho kev ua tau zoo hauv ntau yam kev siv. Lawv siv nyob rau hauv txhua yam ntawm spectrometers mus rau telescopes thiab txawm laser systems. Vim tias lawv muaj peev xwm xa cov feem pua ntawm cov teeb pom kev thoob plaws lub spectrum, cov lo ntsiab muag no muab cov duab zoo nkauj zoo nkauj hauv ntau qhov chaw thiab kev siv.
Broadband AR-coated achromatic lo ntsiab muag yog qhov muaj zog kho qhov muag uas tuaj yeem muab cov duab zoo tshaj plaws ntawm ntau lub teeb wavelengths. Raws li kev siv thev naus laus zis txuas ntxiv mus, cov lo ntsiab muag no yuav tsis muaj qhov tsis ntseeg tias ua lub luag haujlwm tseem ceeb hauv kev tshawb fawb, kev kho mob, thiab suav tsis txheeb lwm yam kev siv.
