Ilensi Yokukhanya Yepulasitiki Ebunjiwe Ngomjovo
Ilensi Yokukhanya Yepulasitiki Ebunjiwe Ngomjovo
Ulwazi lomkhiqizo:
Amasu okubumba ngomjovo we-optical ayindlela engabizi kakhulu yokukhiqiza ilensi yepulasitiki ngokunemba okuphezulu. Ifaneleka ekwenzeni inani elikhulu lelensi yepulasitiki enezindawo eziyindilinga, ezi-aspheric nezikhululekile. Ukubumba ngomjovo kungakhiqiza ama-optics ngezinga eliphezulu lokuphindaphindeka nokunemba. Ikakhulukazi ngenxa yokunemba okwakhelwe ezikhumbeni lapho zenziwe kanye nokunemba kwenqubo yokubumba.
Kunemithelela emithathu emikhulu yokubumba ngokunemba okuphezulu: umshini wokubumba ngomjovo, izikhunta kanye nenqubo yokucindezela. Ikhwalithi yezikhunta izonquma ikhwalithi yengxenye yokugcina ngqo. Izikhunta zakhiwe nge-negative yengxenye. Okusho ukuthi, uma udinga ubuso obuyi-convex, isikhunta sizoba sigobile. Izikhunta zenziwe nge-alloy, futhi zenziwe nge-lathe enembile kakhulu. Izingxenye eziningi zingacindezelwa ngesikhathi esisodwa ngezimbobo eziningi kusikhunta. Akudingeki ukuthi zibe umklamo ofanayo; imodeli ehlukile yelensi ingakhiwa emigodini ehlukene kusikhunta esifanayo futhi yenziwe ngesikhathi esifanayo ukuze kongiwe izindleko zesikhunta, ngenkathi kunciphisa ijubane lokukhiqiza lemodeli ngayinye yezingxenye.
Ukwenziwa kwe-prototyping kuyadingeka ngaphambi kokukhiqizwa kweqembu. Izikhunta zizoklanywa futhi zikhiqizwe ngokusekelwe ezidingweni ze-optical. Zingashintshwa ukuqinisekisa ukuthi izingxenye zokugcina zingahlangabezana nezidingo zamakhasimende. Ekukhiqizweni kweqembu, kuzoba nokuhlolwa kwesihloko sokuqala kanye nokuhlolwa kokukhiqiza ngesikhathi senqubo yokukhiqiza. Futhi ingxenye yokugcina ekhiqizwe izogcinwa ukuze ihlolwe esikhathini esizayo.
Izinto zepulasitiki azikwazi ukumelana namazinga okushisa aphezulu njengoba upende olusetshenziswa
