ABSTRACT:
A flash tube having an elongated tubular envelope containing a pair of anode electrodes disposed at opposite ends and a centrally located cathode electrode which is common to both anodes for simultaneously defining two separate arc discharge paths during operation. The three-electrode configuration is particularly useful in photograhic and photocopying applications for minimizing dark spots and providing a shorter flash duration.
