Ilensi yeglasi yeglasi ebunjiweyo
Ulwazi lweMveliso:
I-lens ye-optical yendabuko iyasila, ipholishelwe ukutshintsha ubuso bayo kwiifom ezithile, ngamanye amagama: ngokusebenzisa "ukuveliswa okubandayo".Ngokwenyani, iilensi zamehlo zinokusekwa “ngokwenziwa kwe-thermal”, okukubunjwa kwelensi ngokuchanekileyo.Izikhewu zeglasi esele zilungisiwe ziya kufakwa kwimingxuma yokungunda, zidlule ngokufudumeza, ukucinezela, ukufakwa kunye nenkqubo yokupholisa, emva koko ihlolwe kwaye idityaniswe.
Umgodi wokungunda unomgangatho ophezulu ophezulu kunye nokuchaneka;iqwalaselwe ukuvelisa ilensi yeemilo ezimiswe kwangaphambili.Iilensi ezibunjiweyo zinezinga eliphezulu lokuphindaphinda kunye nokuchaneka, kuba zonke zinqunywe yimiphezulu kwi-mold cavity.Inkqubo yokubumba ikhawuleza kakhulu kunokuvelisa okubandayo, ngoko ke iindleko zokwenziwa zingalawulwa ukuya kwinqanaba eliphantsi kwimveliso yobuninzi.Ukubumba kuthandwa kakhulu kwintsimi ye-aspheric kunye ne-free-form optical lens production.
Ayizizo zonke izinto zeglasi ezibonakalayo ezifanelekileyo kwi-lens yeglasi yokubumba.Uluhlu lwe-Tg ephantsi (i-Glass Transition Temperature) izinto zeglasi ezibonakalayo ziphuhliswe ngokukodwa ukuhlangabezana neemfuno zenkqubo yokubumba.Ngoluhlu lwe-refracting index ukusuka kwi-1.4 ukuya kwi-2, banokuhlangabezana neemfuno zoyilo lwenkqubo ye-optical kunye nokuveliswa.
Eyona nto ingalunganga yokubumba iglasi yelensi kukuba ayinakusetyenziselwa ukwenza ilensi kububanzi obukhulu, ngenxa yobunzima bokufudumala kunye nokupholisa iqhekeza elikhulu leglasi ngexesha elifutshane.
Iinkcukacha
Ubude be-infraredibonelela ngeglasi lens ezibunjiweyo kunye 1-25 mm ububanzi.Ukungahambi kakuhle komphezulu we-lens surface kunokulawulwa ngaphantsi kwe-0.3micron, i-lens decentration ngaphantsi kwe-1 arc-minute.
