Day Blind UV Deep Cutoff Filters

Sun-blind UV deep cutoff filters are used for the detection of weak UV signals under strong solar irradiation. The filters have good performance with high transmittance in the passband, deep enough cutoff depth in the out-of-band range of the passband, and at the same time meet the requirements of the maximum working angle of incidence. Main applications: power line corona detection, high voltage equipment corona discharge detection, forest fire detection, atmospheric environment research, remote sensing detection equipment, UV imaging alarm.
