Chrome on Glass SFRplusChrome 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. 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).
High Precision SFRplus Target for GL-30E and GLX-30 LightboxesThis chart is produced with a high precision, black and white, LVT film recording process for the best possible density range, low noise, and fine detail. We have assembled multiple pieces of Black and White LVT film to fit the GL-30E Lightbox. This target is suited for customers testing high-resolution imaging systems up to 43 megapixels within compact testing spaces. Color patches are available.
SFRplus Charts for GTI Light BoxesThe SFRplus test chart can be used with the Imatest SFRplus module to measure MTF, lateral chromatic aberration, distortion, and tonal response. 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.
