Day-blind deep ultraviolet cutoff filter

The day-blind ultraviolet deep-cut filter is used for detecting weak ultraviolet signals under intense sunlight. This filter boasts excellent performance: it exhibits high transmittance within the passband, a sufficiently deep cutoff level outside the passband, and simultaneously meets the requirement for the maximum allowable angle of incidence. Major applications include: corona detection on power lines, detection of corona discharge in high-voltage equipment, forest fire detection, atmospheric environmental research, remote sensing detection systems, and ultraviolet imaging alarms.
