1.523 Glass Bifocal Photochromic Photogrey Optical Lens

Kufotokozera Kwachidule:

Pamene kusintha kwa diso la munthu kumafooka chifukwa cha ukalamba, ayenera kuwongolera masomphenya ake padera kwa masomphenya akutali ndi pafupi. Panthawiyi, nthawi zambiri amafunika kuvala magalasi awiri padera, zomwe zimakhala zovuta kwambiri. Choncho, m'pofunika pogaya awiri osiyana mphamvu refractive pa mandala amodzi kukhala magalasi mbali ziwiri. Magalasi oterowo amatchedwa magalasi a bifocal kapena magalasi a bifocal.

Mtundu wa Fusion:ndikuphatikiza zinthu za lens ndi index yotsika kwambiri ya refractive m'dera la concave pa mbale yayikulu pa kutentha kwakukulu, ndipo index ya refractive ya mbale yayikulu ndiyotsika. Kenaka thamangani pamwamba pa chidutswacho kuti mupange kupindika kwa gawo laling'ono kuti likhale logwirizana ndi gawo lalikulu. Palibe lingaliro lakuyika malire. Kuwerenga zowonjezera A kumadalira mphamvu yowonetsera F1 ya kutsogolo kwa masomphenya akutali, kupindika kwa FC ya arc yoyambirira ya concave ndi chiŵerengero cha maphatikizidwe. Chiŵerengero cha fusion ndi mgwirizano wogwira ntchito pakati pa refractive index of two phase fusion lens lens, pomwe n imayimira refractive index of the main glass (nthawi zambiri galasi la korona) ndipo ns imayimira refractive index ya sub-sheet (galasi lamwala) ndi mtengo waukulu, ndiye chiŵerengero cha kuphatikizika k=(n-1)/(nn), kotero A=(F1-FC)/k. Zitha kuwonedwa kuchokera ku ndondomeko yomwe ili pamwambayi kuti, mwachidziwitso, kusintha kokhota kwa kutsogolo kwa mbale yayikulu, kupindika kwa concave arc ndi sub-plate refractive index kungasinthe digiri yowonjezera yowonjezera, koma kwenikweni, imapezeka mwa kusintha. sub-plate refractive index. Tebulo 8-2 likuwonetsa magalasi amiyala omwe amagwiritsidwa ntchito kwambiri padziko lonse lapansi kupanga magalasi ophatikizika apafupipafupi ophatikizika a bifocal.
