1.523 iav Bifocal Photochromic Photogrey Optical Lens

Lus piav qhia luv luv:

Thaum tus neeg lub qhov muag hloov kho tsis muaj zog vim muaj hnub nyoog, nws yuav tsum kho nws lub zeem muag cais rau qhov pom deb thiab ze. Lub sijhawm no, nws feem ntau yuav tsum hnav ob lub tsom iav sib cais, uas yog qhov tsis yooj yim heev. Yog li ntawd, nws yog ib qho tsim nyog yuav tau zom ob lub zog sib txawv ntawm tib lub lens kom dhau los ua lo ntsiab muag hauv ob qhov chaw. Cov lo ntsiab muag zoo li no hu ua bifocal lo ntsiab muag lossis tsom iav bifocal.

Fusion hom:Nws yog los fuse cov khoom siv lens nrog siab refractive index rau hauv qhov chaw concave ntawm lub ntsiab phaj ntawm qhov kub thiab txias, thiab qhov refractive index ntawm lub ntsiab phaj yog tsawg. Tom qab ntawd khiav hauv qhov chaw ntawm lub sub-thooj kom qhov curvature ntawm sub-piece nto zoo ib yam nrog cov khoom tseem ceeb. Tsis muaj kev xav ntawm demarcation. Nyeem ntxiv A nyob ntawm lub zog refractive F1 ntawm sab pem hauv ntej ntawm qhov chaw deb ntawm lub zeem muag, curvature FC ntawm tus thawj concave arc thiab fusion piv. Qhov sib piv fusion yog qhov kev sib raug zoo ntawm qhov ntsuas qhov taw qhia ntawm ob theem fusion lens cov ntaub ntawv, qhov twg n sawv cev rau qhov ntsuas qhov ntsuas ntawm lub iav loj (feem ntau yog lub iav yas) thiab ns sawv cev rau qhov ntsuas qhov ntsuas ntawm cov ntawv sub (flint iav) nrog. tus nqi loj, ces tus fusion ratio k = (n-1) / (nn), yog li A = (F1-FC) / k. Nws tuaj yeem pom los ntawm cov qauv saum toj no uas nyob rau hauv txoj kev xav, hloov lub hauv ntej ntawm lub ntsej muag curvature ntawm lub phaj loj, lub concave arc curvature thiab sub-phaj refractive index tuaj yeem hloov qhov ze ze ntxiv, tab sis qhov tseeb, nws yog feem ntau ua tiav los ntawm kev hloov. sub-phaj refractive index. Table 8-2 qhia qhov refractive index ntawm sub-daim ntawv flint iav feem ntau siv nyob rau hauv lub ntiaj teb no los tsim txawv ze-ntxiv fusion bifocal tsom iav.
