Lub lens hloov xim muaj qhov tsis siv neeg paub qhov system, uas tuaj yeem hloov xim raws li qhov sib txawv ntawm lub teeb sab hauv thiab sab nraum zoov, thiab qhov nrawm nrawm heev. Qhov no tuaj yeem tiv thaiv peb lub qhov muag kom zoo los ntawm kev cuam tshuam ntawm ultraviolet rays, tab sis kuj tuaj yeem zam qhov teeb meem ntawm tsis nco qab hnav looj tsom iav dub.
Kev hloov pauv hloov lub lens tshwj xeeb yog kho nyob rau hauv cov txheej txheem lens txheej. Piv txwv li, kev siv cov spiropyran tebchaw nyob rau saum npoo ntawm lub lens rau high-speed spin txheej, raws li kev siv ntawm lub teeb thiab ultraviolet, siv cov qauv molecular ntawm nws tus kheej thim rov qab qhib thiab kaw kom ua tiav los ntawm lossis thaiv cov nyhuv ntawm lub teeb. .
Qhuav Taw Qhia
Lub lens spherical muaj ib qho arc ntawm ib sab, thaum lub lens aspherical yog tiaj tus. Feem ntau, aspheric lo ntsiab muag muaj cov npoo nyias thiab cov txiaj ntsig zoo dua, tshwj xeeb tshaj yog vim cov duab peripheral pom duab yuav tsis tshua muaj deformed. Tshwj xeeb tshaj yog thaum hmo ntuj, lub teeb zoo li no tawg tau zoo dua thiab tsim nyog rau cov neeg uas tsav tsheb ntau. Thiab kev txhim kho ntawm qhov pom kev pom yuav ua rau cov neeg mob ua haujlwm thiab nyob hauv ntau qhov chaw, xav tias lub xeev ntawm kev pom yuav zoo dua. Yog li ntawd, aspheric lo ntsiab muag feem ntau kim dua li cov lo ntsiab muag kheej kheej, tab sis lawv tuaj yeem ua rau pom pom tseeb dua, tshwj xeeb tshaj yog rau cov khoom nyob ib puag ncig.
