This target provides a highly accurate reference for feature sizes of circles and squares. This target may be used in testing the accuracy of non-contact metrology systems, especially those vulnerable to distortion and blooming.
The high precision pattern is formed in Low Reflection Chromium on a stable Soda Lime Glass substrate in standard microscope slide format. The Low Reflection pattern surface provides a high contrast against a light background, ideal for diffuse lighting or coaxial illumination applications. The pattern is on the first surface, right reading looking at the glass.
