A design of induced transmission filter using metallic and dielectric coatings is introduced . The filter is characterized by its high transmission and wide cut-off band. The electric welding blinkers induced transmission filter is cut off in ultraviolet (UV) and infrared ( IR) , and have a definite transmissivity in visible light band. The electric welding blinkers induced transmission filterwithout glue protecting has been accomp lished. It can eliminate the effect of long wave side transmissive band and shortwave leave out band, and have stable physical capability. The preparation technology and experimental results are dicussed and analyzed.
