Ilensi Yengilazi Ebunjiwe
Ilensi Yengilazi Ebunjiwe
Ulwazi lomkhiqizo:
Ilensi yokubona yendabuko iyagaya, ipholishwe ukuze iguqule indawo yayo ibe amafomu athile, ngamanye amazwi: ngokusebenzisa “ukukhiqiza okubandayo”.Eqinisweni, i-lens ebonakalayo nayo ingakhiwa "ngokukhiqiza okushisayo", okuwukubumba amalensi ngokunemba.Izikhala zengilazi ezakhiwe kusengaphambili zizofakwa emigodini yesikhunta, zidlule ekushiseni, ngokucindezela, ekufakweni nasekupholiseni, bese zihlolwa futhi zihlanganiswe.
I-mold cavity inekhwalithi ephezulu kanye nokunemba;ilungiselelwe ukukhiqiza ilensi yomumo onqunywe kusengaphambili.Amalensi abunjiwe anezinga eliphezulu lokuphindaphinda nokunemba, ngoba wonke anqunywa indawo engaphakathi kwesikhunta.Inqubo yokubumba ishesha kakhulu kunokukhiqiza okubandayo, ngakho-ke izindleko zokwenziwa zingalawulwa ziye ezingeni eliphansi ekukhiqizeni kwenani elikhulu.Ukubunjwa kuthandwa kakhulu emkhakheni wokukhiqiza amalensi optical e-aspheric kanye nefomu yamahhala.
Akuwona wonke ama-glass optical materials afanele ukubunjwa kwe-glass lens.Uchungechunge lwe-Tg ephansi (I-Glass Transition Temperature) izinto zengilazi ezibonakalayo zenziwa ngokukhethekile ukuze zihlangabezane nemfuneko yenqubo yokubumba.Ngobubanzi benkomba e-refracting ukusuka ku-1.4 ukuya ku-2, bangahlangabezana nezidingo zomklamo nokukhiqizwa kwesistimu yokubona okuningi.
Ububi obukhulu bokubumba ilensi yengilazi ukuthi ayikwazi ukusetshenziselwa ukwenza ilensi ngobubanzi obukhulu, ikakhulukazi ngenxa yobunzima bokufudumala nokupholisa ingxenye enkulu yengilazi ngesikhathi esifushane.
Imininingwane
I-wavelength infraredinikeza ilensi ebunjiwe yengilazi enobubanzi obungu-1-25 mm.Ukungalungi kwangaphezulu kwendawo yelensi kungalawulwa kube ngaphansi kuka-0.3micron, ukuhlukaniswa kwelensi ngaphansi kwe-arc-minute engu-1.
| Okubalulekile | Ingilazi ye-Optical |
| Ububanzi | 1mm-25mm |
| Isimo | I-aspheric/ifomu lamahhala |
| Ukwehliswa | <1 arc-minute |
| Ukungajwayelekile kwendawo | < 0.3 micron |
| Imbobo ecacile | >90% |
| Ukugqoka | Ifilimu ye-Dielectric/Metallic |
Amazwana:
Ukwenza ngendlela oyifisayo kuyatholakala kulo mkhiqizo ukuze uvumelane nezidingo zakho zobuchwepheshe.Sazise imininingwane yakho edingekayo.
IZIGABA ZOMKHIQIZO
I-Wavelength ibigxile ekuhlinzekeni ngemikhiqizo ye-optical enembayo ephezulu iminyaka engama-20
