The Graticules Div. of Pyser-SGI Ltd. has introduced a high-precision image analysis standard that provides four test areas for calibrating image analysis systems and identifying deviations and distortions in optical imaging systems. The standard has a square grid accuracy of ±0.1 µm and a dot accuracy of ±0.3 µm; the smallest and largest two dots on the root-2 array have an accuracy of ±0.5 µm. The image analysis standard is on a 75 x 25-mm slide and also can be used as a high-precision stage micrometer.
