The SFRplus chart offers significant advantages over commonly used charts such as the ISO 12233 chart, including
This chart has an active chart area of 48.3 cm x 26.81 cm (19 in x 10.56 in) in a total film size of 30.48 cm x 50.8 cm (12 in x 20 in). Bar-to-bar height is 252 mm (9.92 in).
This 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. The edges have an MTF50 >= 10 cycles/mm, which is about 2 times better than the best inkjet charts. For more information please take a look at our transmissive chart quality comparison! The large patterns are fine enough to produce good results with up to 30 megapixel cameras.
With 12 rigorous quality inspection processes in place, we ensure a high yield rate of up to 98% for batch processed precision parts.
