Khoom nta
1.Cov yam ntxwv ntawm CR39 Lens:
① CR-39 monomer nrog ruaj khov zoo thiab muaj peev xwm ntau lawm.Nws zoo siab txais tos nyob rau hauv Teb chaws Europe, South America thiab Asia.UC yog nrov nyob rau hauv kev ua lag luam tab sis peb kuj muab kev pab cuam HMC thiab HC.
②CR-39 yog qhov ua tau zoo optically dua li Polycarbonate.Nws nyiam tint, thiab tuav tint zoo dua li lwm cov ntaub ntawv lens.Nws yog cov khoom siv zoo rau ob qho tib si looj tsom iav dub thiab tsom iav tshuaj.
③ Cov lo ntsiab muag ua los ntawm CR-39 monomer yog khawb-tiv taus, lub teeb yuag, tsis muaj chromatic aberration dua li cov lo ntsiab muag polycarbonate, thiab sawv ntsug rau cov khoom siv hluav taws xob thiab cov khoom siv tu tsev.
④CR-39 yas lo ntsiab muag tsis pos tuaj yooj yim li iav lo ntsiab muag.Thaum welding los yog sib tsoo spatter yuav pit los yog mus tas li rau iav lo ntsiab muag, nws tsis ua raws li cov ntaub ntawv yas lo ntsiab muag.
2.Qhov zoo ntawm 1.499 Performance index
①Qhov zoo dua ntawm lwm qhov ntsuas qhov ntsuas hauv qhov tawv thiab tawv, muaj kev cuam tshuam siab.
②Qhov yooj yim tinted dua li lwm qhov ntsuas qhov ntsuas.
③ Lub transmittance ntau dua li piv nrog rau lwm qhov ntsuas qhov ntsuas.
④ Tus nqi siab dua ABBE muab qhov kev pom zoo tshaj plaws.
⑤Qhov ntau txhim khu kev qha thiab zoo ib yam lens khoom lub cev thiab optically.
⑥Qhov nrov dua nyob rau hauv nruab nrab lub teb chaws
3. Qhov txawv ntawm HC, HMC thiab SHC yog dab tsi?
| Txheej tawv | AR txheej / Hard txheej txheej | Super hydrophobic txheej |
| ua rau lub lens uncoated nyuaj thiab tsub kom lub abrasion kuj | tsub kom lub transmittance ntawm lub lens thiab txo cov reflections nto | ua rau lub lens waterproof, antistatic, anti plam thiab roj kuj |
