1.56 Semi Finished Progressive photo grey Optical Lens

Kufotokozera Kwachidule:

Ma lens refractive index ndi apamwamba, magalasi ocheperako, kuchuluka kwa kachulukidwe, kuuma komanso bwinoko, m'malo mwake, m'munsimu index ya refractive, yokulirapo ya mandala, yocheperako, kuuma kumakhalanso kosauka, magalasi ambiri olimba kwambiri, kotero refractive index nthawi zambiri imakhala pafupifupi 1.7, ndipo kuuma kwa filimu ya utomoni kumakhala kocheperako, index ya refractive ndiyotsika, kagawo kakang'ono pamsika pakali pano ndiye index yodziwika bwino ya 1.499 kapena kupitilira apo, Zabwino pang'ono ndi mtundu wowonda kwambiri, yomwe ili ndi refractive index ya 1.56 ndipo imagwiritsidwanso ntchito kwambiri.

Magalasi opitilira ma multifocal

Ndi ma lens angapo, ma lens amapindika kuchokera pamwamba mpaka pansi asanaonjezeke mosalekeza, mphamvu ya refractive yochokera m'chigawo ili kumtunda kwa mandala ndikutali, pang'onopang'ono, ikuwonjezeka mosalekeza, mpaka pafupifupi pansi pa disolo ndi dera. anafika chiwerengero pafupifupi ndi diopta, magalasi akhoza kuona, mtunda akhoza kuona pafupi kachiwiri, mukhoza kuona chinthu mtunda.Magalasi opita patsogolo amafotokozedwa ngati "magalasi omwe amawonekera," ndipo magalasi amatha kugwiritsidwa ntchito ngati magalasi owonjezera.Mwachitsanzo, ndi oyenera ophunzira kuwerenga ndi kulemba ophunzira ntchito mandala (onani pa bolodi, kuwerenga mabuku, homuweki ndi zofuna zina zooneka), oyenera woyera-kolala khamu kutopa kukana kwa disolo (kuti agwirizane ndi kutali, pakati ndi pafupi zithunzi lophimba, zosavuta ntchito), kuzolowera kwa zaka zapakati ndi anthu akale d mulingo woyenera kwambiri magalasi patsogolo (ufulu mwambo yokhota kumapeto pamwamba, chabwino, sing'anga, pafupi lophimba, osati chizungulire ubongo kuwonjezera).

Mau oyamba a Zopanga

Mndandanda waukulu wa refractive wa mandala umaphatikizapo: 1.56, 1.60, 1.67, 1.71, 1.74 ndi zina zotero.Mlozera wa refractive wa mandala umakhala wocheperako komanso wopepuka.Komabe, kuchuluka kwa refractive index ya mandala ndikwabwinoko.Kawirikawiri, chiwerengero cha refractive cha lens chikakhala chokwera, chiwerengero cha Abbe chimakhala chotsika kwambiri ndipo kufalikira kumawonekera.
