The SFRplus test chart can be used with the SFRplus module in Imatest 3.2 or later 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,
  4. full support for automated testing.


SFRplus charts on photographic paper have the following properties:

  • 5x9 grid pattern
  • Active Area: 223mm x 356mm. It is recommended these charts be used to test imaging systems with sensors up to 3 MP. For larger image sensor sizes, please see other SFRplus chart listings. The active area of the chart includes white space above and below the top and bottom distortion bars. It is typically about 10% larger than the printed area, which is bounded by the distortion bars on top and bottom. White space is included because test images of the chart must include this white space in order to enable automated processing in SFRplus software.
  • Contrast levels: 10:1 and 2:1 contrast levels to analyze non-linear signal processing

FAQs About  SFRPlus Test Charts

Assembling the light booth entails connecting the panels, fixing the light fixtures, fitting the tubes, and calibrating the lights according to our 3nh manufacturer’s instructional and safety guidelines.


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. 

L*a*b* is an L*a*b* color space. The L* is a measure of lightness (as 0 = black, 100 = white), a* indicates the green to red axis, and b* indicates the blue to yellow axis. It is also common in color measurement in terms of precision and reliability.


Colors look different under various lights mainly because of metamerism—a phenomenon where two colors that match under one light source fail to match under another, caused by differences in the spectral composition of light.

Different lighting varies the color perception of objects. Warm light, like that from incandescent bulbs, tends to make colors more yellow, while daylight presents a bluish tint. Our color vision system plays a compensating role using a mechanism called color constancy.

Every light source emits light with a unique "spectral fingerprint" (i.e., the range and intensity of wavelengths it contains). This directly affects how an object’s surface reflects light and how our eyes perceive its color.

  • The core function of a portable multi-parameter colorimeter is to measure various color parameters, including color difference and chromaticity, and it is mainly used in scenarios requiring precise color management.

  • 3nh portable colorimeters are designed specifically for the above needs, combining portability and high-precision color measurement, making them especially suitable for on-site rapid testing.

  • Our portable colorimeter products effectively improve color quality control efficiency and help users optimize workflows.
