Uyini umehluko phakathi kwamalensi e-telecentric kanye ne-f-theta?

Phakathi kwezingxenye ezihlukahlukene ze-optical ezisetshenziswa ezinhlelweni ze-laser, i I-Telecentric Lens kanye ne f-theta Ilensi ziyizinhlobo ezimbili ezivamile ezinemisebenzi ehluke ngokusobala. I I-Telecentric Lens isetshenziswa kabanzi ekulinganisweni nasekuhloleni okunembayo okuphezulu, kuyilapho i I-F-Theta Lens isebenza njengengxenye ewumgogodla ezinhlelweni zokumaka nokucubungula i-laser. Ngayinye idlala indima ebalulekile ekukhiqizweni kwezimboni, ifeze umgomo wayo futhi inikeze ukwesekwa okuqinile okubalulekile.

I-Telecentric Lens iwuhlobo olukhethekile lwamalensi ezimboni futhi futhi iyithuluzi lochwepheshe lokulinganisa okunembayo. Ukuklama kwayo okubonakalayo kuqinisekisa ukuthi imisebe emikhulu engena kwilensi ihambisana ne-optical axis.I-optical path design design iqinisekisa ukuthi imisebe emikhulu engena ku-lens ihlala ihambisana ne-optical axis. Ngamanye amazwi, kungakhathaliseki ibanga lento ukusuka ku-lens—kungakhathaliseki ukuthi iseduze noma ikude—usayizi wesithombe uhlala unjalo. Ngokuphawulekayo, lo mklamo unciphisa kakhulu ukuhlanekezela kwesithombe namaphutha angu-angular, unikeza ilensi inzuzo engenakubuyiseleka ekulinganisweni okunembayo okuphezulu kanye nezinhlelo zokusebenza zokuhlola ikhwalithi.

Izinhlelo zokusebenza eziyinhloko nobubanzi be-wavelength: ukusika ngokunemba, ukubhola, njll. Ububanzi be-wavelength obumboziwe buhlanganisa 9.3 μm, 10.6 μm, 1030–1080 nm, 532 nm, 355 nm, kanye no-266 nm.

I-F-Theta Lens ifana "neqhawe" lomhlaba wokuskena nge-laser! Iphinde ihambisane namagama amaningana apholile, njengelensi yasensimini, ilensi yokugxila eyisicaba, noma ilensi yomugqa. “Amandla amakhulu” ayo angachazwa ngefomula elula: ubude besithombe = ubude obugxilile × i-engeli yokuskena (y = f × θ). Kuzwakala kufana nomlingo wezibalo, akunjalo?

Ezinkambini ezinemba okuphezulu njengokumaka nge-laser, I-Laser Welding, nokusika nge-laser, i-F-Theta Lens ngempela “iqhawe elingaculwanga” ngemuva kwezigcawu. Umklamo wayo awusho lutho ngobuhlakani! Ngemva kokuthi i-laser beam iphambukiswe “induku” ye-galvanometer, i-F-Theta Lens iqondisa uhlaka ngendlela ecishe ilingane kahle, iyiskena kancane endizeni esebenzayo ukuze yakhe amachashazi anosayizi ofanayo, anembe kakhulu. Kufana nokunikeza ugongolo lwe-laser “amehlo aqondile,” ukuqinisekisa ukuthi lufinyelela wonke amaphuzu adingekayo kalula.

Ngamafuphi, i-Telecentric Lens kanye ne-F-Theta Lens zifana “nezimo eziqinisayo” emikhakheni yokuhlola umbono wezimboni kanye nokucutshungulwa kwe-laser. Ngazo, zombili izizinda zingasebenza ngokuzinza, ngokunemba, nangokunemba okuphelele!
