A laser beam collimator system with a high numerical aperture lens and a 1.2 mm aperture masked collimator is proposed to realize a miniature high-resolution ternary barcode detection system in which high-density ternary barcodes can be detected. It was clarified that a 1.2 mm aperture mask combined with a 0.5 NA lens is suitable for maintaining the laser beam width at less than 150 flm over a wide range of more than 4.5 cm. The laser head with this collimator system was applied to a ternary barcode detection system. It was confirmed that the detection system could detect the ternary barcode with a minimum bar width of 0.2 mm over a practical detection range greater than 5 cm (which conventional detection systems could not detect) by optimizing the clamp bias voltage in the clamping circuit to -0.8 V, and the gray bar concentration to 58 %. This collimator system has potential applications in high-speed, high-resolution ternary or binary barcode detection systems.
