Ilensi yeglasi ebonisiweyo
Ulwazi lwemveliso:
Iilensi zemveli ze-optical ziyagaywa, zipolishwe ukuze zitshintshe umphezulu wazo ube ziimo ezithile, ngamanye amazwi: ngokusebenzisa "ukwenziwa okubandayo". Enyanisweni, ilensi ye-optical inokwenziwa ngokusebenzisa "ukwenziwa okushushu", okukubumba ilensi ngendlela echanekileyo. Iiblanks zeglasi ezenziwe kwangaphambili ziya kufakwa kwimingxuma ye-mold, zidlule kwinkqubo yokufudumeza, yokucinezela, yokufunxa kunye neyokupholisa, emva koko zihlolwe kwaye zihlanganiswe.
Umngxuma wokubumba unomgangatho ophezulu kunye nokuchaneka komphezulu; wenzelwe ukuvelisa ilensi yeemilo ezimiselwe kwangaphambili. Iilensi ezibunjiweyo zinomlinganiselo ophezulu wokuphindaphindeka kunye nokuchaneka, kuba zonke zimiselwa yimiphezulu ekwimngxuma wokubumba. Inkqubo yokubumba ikhawuleza kakhulu kunemveliso ebandayo, ngoko ke iindleko zokwenza zinokulawulwa kwinqanaba eliphantsi kwimveliso eninzi. Ukubumba kuthandwa kakhulu kwicandelo lokuvelisa iilensi ze-aspheric kunye ne-free-form optical.
Ayizizo zonke izinto zeglasi ezikhanyayo ezifanelekileyo ukubumba ilensi yeglasi. Uthotho lwezinto zeglasi ezikhanyayo zeTg (Glass Transition Temperature) ezisezantsi zenziwe ngokukodwa ukuhlangabezana neemfuno zenkqubo yokubumba. Ngoluhlu lwe-refracting index ukusuka kwi-1.4 ukuya kwi-2, zinokuhlangabezana neemfuno zoyilo lwenkqubo ye-optical kunye nemveliso.
Eyona ngxaki inkulu yokubumba iilensi zeglasi kukuba azinakusetyenziswa ukwenza iilensi ngobubanzi obukhulu, ikakhulu ngenxa yobunzima bokufudumeza nokupholisa iindawo ezinkulu zeglasi ngexesha elifutshane.
Iinkcukacha
Ubude be-infraredIbonelela ngelensi ebunjiweyo yeglasi enobubanzi obuyi-1-25 mm. Ukungalungelelani komphezulu welensi kunokulawulwa ukuya ngaphantsi kwe-0.3 micron, ukuhlukaniswa kwelensi kungaphantsi kwe-1 arc-minute.
