Please Note: Chrome-on-glass charts are uni-tone, have 10:1 contrast, and do not include a step-chart. This means that they do not support calculation of tonal response curves. These charts are mounted on a 50X50 mm substrate. 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). Please contact sales@imatest.com with any questions regarding differences between this chart and the standard SFRplus chart design or with requests for custom charts.
The Unitone SFRplus test chart can be used with the SFRplus module in Imatest 3.2 or later to measure MTF, lateral chromatic aberration, and distortion. The SFRplus module features fully automated region-of-interest detection. The SFRplus chart offers significant advantages over commonly used charts such as the ISO 12233 chart, including 1) much less wasted area, 2) the ability to produce a map of sharpness over the sensor surface, 3) better measurement accuracy due to the lower contrast, and 4) full support for automated testing.
