Star Target Arrays

Detect Aberrations at Various Field Points

Our star target arrays are designed to identify focus errors and astigmatism along field points in the image of a vision system. With star targets located at the center, corner, and along the diagonals of the sensor, determining precision location and amplitude of the problem areas couldn’t be easier. The small array features unresolved centers of 0.1mm, whereas the large array features unresolved centers of 0.15mm.
