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

Colorimeters have fixed wavelength filters and LEDs; it is less precise and simpler. Monochromators are applied to spectrophotometers, which scan a spectrum of wavelengths. Giving more detailed spectral information. Spectrophotometers are more sensitive and flexible in complicated analyses.


A service is made up of tub replacement, light source recalibration, internal cleaning, verification of service and color certification retention so that all compliance color standards are retained. 


The haze meter test assesses the degree of light scattering that occurs when light traverses a transparent or translucent material, producing a percentage that quantifies example or cloudiness.

Spectrophotometers can only measure haze if it has haze measuring capabilities, as many measure color and transmittance.


Colorimetry is a method that applies color intensity to ascertain the chemical concentrations. It is founded on Beer-Lambert Law, whereby the absorbance at a given wavelength is proportional to the concentration. It is popular in environmental and biochemical testing.

Gloss level is not given out in percentage but in gloss units (GU). In practice, however, 100 GU is considered 100 percent reflective. To contrast visually, the 20-40 GU is a low-gloss surface, and 85 or more is almost 100 percent mirror-like reflection.
