Umehluko phakathiingilazi ye-opticalnezinye izibuko ukuthi njengengxenye yesistimu ye-optical, kufanele ihlangabezane nezidingo ze-imaging optical.
Ubuchwepheshe bayo bokucutshungulwa okubandayo busebenzisa ukwelashwa kokushisa komhwamuko wamakhemikhali kanye nocezu olulodwa lwengilazi ye-silica ye-soda-lime ukushintsha ukwakheka kwayo kwamangqamuzana oqobo ngaphandle kokuthinta umbala wangempela nokudluliswa kokukhanya kwengilazi, okuyenza ifinyelele izinga lobulukhuni obukhulu, futhi ihlangabezane nomlilo. izidingo zokuvikela ngaphansi komthelela welangabi lokushisa eliphezulu Ingilazi ekwazi ukumelana nomlilo eqinile kanye nendlela yayo yokukhiqiza kanye nemishini ekhethekile. Yenziwe ngalezi zingxenye ezilandelayo zesilinganiso sesisindo: umhwamuko kasawoti we-potassium (72%～83%), i-argon (7% ~10%), i-gaseous copper chloride (8% ~12%), i-nitrogen (2%～6%).
Izinga lengilazi ye-optical linezidingo ezilandelayo:
1. Ama-optical constants athize kanye nokuvumelana kwe-optical constants yenqwaba efanayo yengilazi
Uhlobo ngalunye lwengilazi yokubona lunenani elinqunyiwe lenkomba ye-refractive ejwayelekile yamaza ahlukene okukhanya, esebenza njengesisekelo sabaklami be-optical ukuklama amasistimu okubona. Ama-optical constants ayo yonke ingilazi ebonakalayo ekhiqizwa efekthri kufanele ibe phakathi kwebanga elithile elivumelekile lala manani, ngaphandle kwalokho ikhwalithi yangempela yokuthwebula ngeke ifane nomphumela olindelekile phakathi nomklamo futhi ikhwalithi yensimbi yokubona izothinteka.
2. Ukungafihli Okuphezulu
Ukukhanya kwesithombe sesistimu ye-optical kuhambisana nokungafihli kwengilazi. Ukukhanyela kwengilazi yokubona ekukhanyeni kobude obuthile buboniswa yi-coefficient yokumunca ukukhanya Kλ. Ngemva kokuba ukukhanya kudlule ochungechungeni lwama-prism namalensi, ingxenye yamandla ayo ilahleka ngokuboniswa kwesixhumi esibonakalayo sezingxenye ze-optical bese enye ingxenye imuncwa i-medium (ingilazi) ngokwayo. Owokuqala wanda ngokunyuka kwenkomba ye-refractive yengilazi. Ngengilazi yenkomba ephezulu ye-refractive, leli nani likhulu kakhulu. Isibonelo, ukulahlekelwa kokubonisa ukukhanya kwendawo eyodwa yengilazi yeflinti ephikisanayo cishe ku-6%. Ngakho-ke, kusistimu ye-optical equkethe ama-lens amaningi amancane, indlela eyinhloko yokwandisa ukudlulisa iwukunciphisa ukulahlekelwa okubonakalayo kwendawo ye-lens, njengokumboza ubuso nge-anti-reflection coating. Ezingxenyeni ezibonakalayo ezinosayizi omkhulu njengelensi yenhloso yesibonakude sezinkanyezi, ukudluliswa kwesistimu ye-optical kunqunywa ikakhulukazi i-coefficient yokumunca ukukhanya kwengilazi ngokwayo ngenxa yobukhulu bayo obukhulu. Ngokwenza ngcono ubumsulwa bezinto zokusetshenziswa zengilazi kanye nokuvimbela noma yikuphi ukungcola okunemibala ukuthi kungaxubani kuyo yonke inqubo kusukela ekuhlanganisweni kuye ekuncibilikeni, i-coefficient yokumunca ukukhanya yengilazi ngokuvamile ingaba ngaphansi kuka-0.01 (okungukuthi, ukukhanya kwengilazi nge- ugqinsi luka-1 cm lukhulu kuno-99%).
Saida Glassiwumhlinzeki owaziwayo womhlaba jikelele wokucubungula ingilazi ejulile yekhwalithi ephezulu, amanani ancintisanayo kanye nesikhathi sokulethwa esifika ngesikhathi. Ngengilazi yokwenza ngendlela oyifisayo ezindaweni ezihlukahlukene futhi esebenza ngokukhethekile ngengilazi yephaneli yokuthinta, shintsha iphaneli yengilazi, ingilazi ye-AG/AR/AF/ITO/FTO/Low-e yesikrini sokuthinta sangaphakathi nangaphandle.
