Abstract

Solar blind ultraviolet imaging detector is useful in detecting corona of overhead electric transmission lines, reducing power equipment damage. UV lens are the core of solar blind ultraviolet imaging detector. Their property affects the performance of the whole detector directly. In view of the problems of insufficient light energy utilization in corona detection system, the paper proposes a coaxial optical system based on wavelength and light separation, which eliminates the center field, enlarges the aperture of UV objective, and effectively improves the energy gathering ability of corona detection system. The mean square of the designed UV objective full view and whole detection range is less than 0.14mm, meeting the requirement of ultraviolet corona detection resolution. Compared with foreign ultraviolet optical system imaging detectors, the proposed solar blind ultraviolet imaging detector with coaxial optical system has better energy collection efficiency.
