Ilensi yokubona

I-Optical lens yilens eyenziwe ngeglasi ebonakalayo.Inkcazo yeglasi yeglasi yeglasi eneepropati ezifanayo kunye neemfuneko ezithile kwiipropati ezibonakalayo ezifana ne-refractive index, i-dispersion, transmittance, i-spectral transmittance kunye ne-absorption light.I-Glass enokutshintsha indlela yokusabalalisa ukukhanya kunye nokusabalalisa kwe-spectral ehambelanayo ye-ultraviolet, ukukhanya okubonakalayo okanye kwe-infrared.Ngengqiqo emxinwa, iglasi yokukhanya ibhekisa kwiglasi ekhanyayo engenambala;Ngengqiqo ebanzi, iglasi yokukhanya ikwabandakanya iglasi yeglasi enemibala, iglasi yelaser, iglasi yequartz optical, iglasi ye-anti radiation, iglasi ye-ultraviolet infrared optical glass, iglasi ye-acoustooptic, iglasi yemagneto-optical kunye neglasi yephotochromic.Iglasi yokukhanya ingasetyenziselwa ukwenza iilensi, iiprism, izipili kunye neefestile kwizixhobo zokukhanya.Amacandelo ahlanganiswe ngeglasi ye-optical amacandelo aphambili kwizixhobo ze-optical.

Iglasi eyayisetyenziswa ekuqaleni ukwenza iilensi ngamaqhuma akwiglasi yefestile okanye iibhotile zewayini.Ubume bufana "nesithsaba", apho igama leglasi yesithsaba okanye isithsaba seglasi yeglasi.Ngelo xesha, iglasi yayingalingani kwaye igwebu.Ukongeza kwiglasi yesithsaba, kukho olunye uhlobo lweglasi elityebileyo enomxholo ophezulu wokukhokela.Malunga nowe-1790, uPierre Louis junnard, umFrentshi, wafumanisa ukuba isosi yeglasi eshukumayo inokwenza iglasi ibe nokwakheka okufanayo.Ngowe-1884, uErnst Abbe no-Otto Schott beZeiss baseka iSchott glaswerke Ag eJena, eJamani, baza benza iiglasi ezininzi zamehlo kwiminyaka nje embalwa.Phakathi kwabo, ukuveliswa kweglasi yesithsaba se-barium kunye ne-high refractive index yenye yeempumelelo ezibalulekileyo ze-Schott glass factory.

Iglasi ye-Optical ixutywe kunye ne-oxides ye-silicon ephezulu ecocekileyo, i-boron, i-sodium, i-potassium, i-zinc, i-lead, i-magnesium, i-calcium kunye ne-barium ngokwefomula ethile, inyibilika kwiqondo lokushisa eliphezulu kwi-crucible platinum, ixutywe ngokulinganayo kunye namaza e-ultrasonic ukususa ama-bubbles. ;Emva koko pholisa kancinci ixesha elide ukuphepha uxinzelelo lwangaphakathi kwibhloko yeglasi.Ibhloko yeglasi epholileyo kufuneka ilinganiswe ngezixhobo ze-optical ukujonga ukuba ukucoceka, ukungafihli, ukufana, isalathisi se-refractive kunye ne-dispersion index iyahlangabezana neenkcukacha.Ibhloko yeglasi evunyiweyo iyafudunyezwa ize yenziwe i-optical lens rough embryo.
