National-Standard Type A Resolution Chart A5
The resolution target is a key component for evaluating optical-system image quality. This series follows Type A targets in JB/T9328-1999,with A1–A7 sizes. Each has25units,each with four equally spaced stripe groups:horizontal,vertical,45°and135°. Positive and negative patterns are available;positive suits front illumination/general use,and negative suits back/strong illumination. Photolithographic etching and laser direct writing produce clear,uniform line pairs without broken/doubled lines and with nonfading markings.
