A high-resolution tri-electrode pickup tube for a single-tube color camera has been successfully developed. The tube's target consists of RGB color filter stripes, three sets of signal electrode stripes, and an Se-As-Te amorphous photoconductor. Signal electrode stripes with tapered edges at an angle less than 15°, and an ultra-thin conductive layer deposited on gaps between the signal electrode stripes, have been employed to maintain the characteristics of the amorphous photoconductor. The tube's resolution has reached 500 TV lines, owing to the 1059 fine color filter stripes employed.
