This transmissive (backlit) 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.

Size

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.

FAQs About  SFRPlus Test Charts

A coating thickness gauge measures film layers by identifying shifts in magnetic flux, eddy currents, or ultrasonic echoes as they penetrate the coating. The gauge calculates thickness based on the magnitude of these signals. This universally accepted approach results in quick, reliable, and non-invasive measurements. 

A haze meter should be calibrated every 6 months, or more frequently if used for certain quality control processes.


To keep a neutral background, helping to reduce color distortion and bias.

Each haze test can take from 3 to 10 seconds depending on the device and the type of sample.


The most common standard measuring gloss is ASTM D523, which covers the procedures of using a gloss meter at 20°, 60°, and 85° angles. The other international standard that is widely used in industrial and laboratory applications is the ISO 2813.


A colorimeter is a scientific instrument used to measure and analyze the color characteristics of objects or materials. It quantifies color by evaluating specific parameters related to human visual perception and standardized color spaces.
