CP127

CMS Depth-of-Field Test Chart

The CP127 is a resolution and depth-of-field (DOF) test chart compliant with ISO16505. The chart pattern is surrounded by 18% neutral gray reflection to provide a stable background under varying lighting conditions. It includes a wedge pattern, slanted edges, and two additional parallel stripe patterns with defined spatial frequencies, enabling accurate evaluation of imaging system resolution and depth-of-field performance.
