Aluminiyamu wokutira Mirror kwa Slit nyali
Mafotokozedwe Akatundu
Magalasi amtundu wotere amagwiritsidwa ntchito popanga nyali mu ophthalmology kuti apereke chithunzi chomveka bwino cha diso la wodwalayo. Chophimba cha aluminiyamu pagalasi la nyali chong'ambika chimagwira ntchito ngati chowunikira, chomwe chimalola kuti kuwala kulowetsedwe kumakona osiyanasiyana kupyolera mwa wophunzira wa wodwalayo ndi m'diso.
Chophimba choteteza cha aluminiyamu chimagwiritsidwa ntchito pogwiritsa ntchito njira yotchedwa vacuum deposition. Izi zimaphatikizapo kutenthetsa aluminiyumu mu chipinda chochotseramo mpweya, zomwe zimapangitsa kuti zisasunthike kenako n'kukhala pamwamba pa galasi. Makulidwe a zokutira amatha kuwongoleredwa kuti awonetsetse bwino komanso kukhazikika.
Magalasi oteteza Aluminium amakondedwa kuposa magalasi amtundu wina wa nyali zong'ambika chifukwa ali ndi mawonekedwe owoneka bwino, osamva dzimbiri ndi abrasion, komanso ndi opepuka. Kuwala kwa galasi kumafunika kusamalidwa kuti zitsimikizidwe kuti zikuyenda bwino, chifukwa chake, kusamala kuyenera kuchitidwa kuti zisawononge kapena kuwononga galasi pakugwiritsa ntchito kapena kuyeretsa.
Nyali yong'ambika ndi chida chofunikira chodziwira chomwe chimagwiritsidwa ntchito ndi ophthalmologists kuyang'ana diso. Nyali yong'ambika imathandiza madokotala kuti aone mbali zosiyanasiyana za diso, monga diso, iris, lens, ndi retina. Chimodzi mwa zigawo zofunika kwambiri za nyali yodulidwa ndi galasi, yomwe imagwiritsidwa ntchito popereka chithunzi chomveka komanso chakuthwa cha diso. Magalasi okutidwa ndi aluminiyamu atchuka kwambiri m'zaka zaposachedwa chifukwa cha mawonekedwe awo apamwamba komanso olimba.
Magalasi opangidwa ndi aluminiyamu ndi galasi lapamwamba kwambiri lopangidwa ndi galasi. Galasiyo imakutidwa ndi aluminiyamu yopyapyala, zomwe zimapangitsa kuti galasi likhale lowoneka bwino komanso lowoneka bwino. Galasiyo idapangidwa kuti ikhale mu nyali yotchinga, pomwe imawonetsa kuwala ndi zithunzi kuchokera m'diso. Chophimba cha aluminiyamu pagalasi chimapereka chithunzithunzi chapafupi cha kuwala, kuonetsetsa kuti chithunzicho chikuwoneka bwino komanso chowala.
Chimodzi mwazinthu zodziwika bwino za magalasi opangidwa ndi aluminiyamu ndi kulimba kwawo. Galasiyo imapangidwa ndi zinthu zapamwamba kwambiri zomwe zimakana kuwonongeka chifukwa cha kugwedezeka kwa thupi, kukwapula, ndi mankhwala. Galasiyo imapangidwa kuti igwirizane ndi zovuta zomwe zimagwiritsidwa ntchito tsiku ndi tsiku, zomwe zimapangitsa kuti zikhale zodalirika komanso zotsika mtengo za nyali yotchinga.
Magalasi opangidwa ndi aluminiyamu amaperekanso kusiyana kwakukulu. Kuwoneka bwino kwa galasi kumalola akatswiri a ophthalmologists kuti azitha kuona bwino mwatsatanetsatane wa maso, zomwe zimapangitsa kuti zikhale zosavuta kupeza matenda osiyanasiyana a maso. Chifukwa cha mawonekedwe ake apamwamba kwambiri, magalasi opangidwa ndi aluminiyamu akhala chida chofunikira kwa akatswiri a maso pakuzindikira kwawo tsiku ndi tsiku ndi chithandizo chawo.
Mwachidule, galasi lopangidwa ndi aluminiyamu ndi gawo lofunika kwambiri la nyali yowonongeka, kupereka ophthalmologists zithunzi zomveka bwino komanso zakuthwa. Zida zapamwamba zomwe zimagwiritsidwa ntchito popanga galasi zimapangitsa kuti zikhale zodalirika komanso zokhazikika, kuonetsetsa kuti zimatha kupirira zovuta za tsiku ndi tsiku. Kuwoneka bwino kwake komanso kukhazikika kwanthawi yayitali kumapangitsa kuti ikhale ndalama zabwino kwambiri kwa dokotala aliyense wamaso yemwe akufuna kupititsa patsogolo luso lawo lozindikira.
