The utility model relates to a laser dual beam holographic plate-making instrument, which is composed of a main control microcomputer, a microcomputer controller, a stabilized power supply, an autocollimation laser source, an automatic shutter, a beam-expanding optical system, an objective lens array, a self control magnetic dual-beam rotating system, and a double coordinate guideway assembly. The automatic shutter is positioned between the autocollimation laser source and the beam-expanding optical system. The objective lens array, the self control magnetic dual-beam rotating system, the beam-expanding optical system and the double coordinate guideway assembly that is provided with photosensory plates are arranged at the lower side of the beam-expanding optical system from top to bottom. The utility model has the advantages of small size, light weight, high precision, complete function, full automation and high speed, and the plate-making efficiency of the utility model can be a plurality of times to scores of times higher than that of a single lens.
