Chrome on Glass charts are unitone, have 10:1 contrast, and do not include a stepchart.
This means that they do not support calculation of tonal response curves. These charts are mounted on a 2" x 2" (50.8mm x 50.8mm) substrate that is 0.059" (1.5mm) thick. The star pattern is strictly for use as a focusing aid, and is not intended as a testing feature (i.e., as a star chart).
All SineImage charts can be customized to fit your testing needs. Please contact your reseller for details.
