The SFRplus test chart can be used with the SFRplus module in Imatest 3.2 or later to measure MTF, lateral chromatic aberration, distortion, tonal response, and color accuracy. 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.

This chart is recommended for most standard testing setups and devices. Choose a size based on your sensor and setup limitations.


Options include:

  • Grid: 5x9 grids are recommended for for typical DSLR formats with aspect ratios of 3:2
  • Paper Size and Active Area Options

    This chart is available in three sizes. It is recommended that the medium sized charts be used to test imaging systems with sensors up to 12 MP, the large charts be used for testing of sensors up to approximately 24 MP, and the extra-large charts be used for sensor sizes above 24 MP.

    Active Area

    The active area of the chart includes white space above and below the top and bottom distortion bars. It is slightly larger than the printed area, which is bounded by the distortion bars on top and bottom. White space is included in active area because test images of the chart must include this white space in order to enable automated processing in SFRplus software.

  • Paper/ink type: Matte paper/ink can be used to reduce reflected light and allow for easier lighting setups
  • Contrast levels: 4:1 contrast ratio for new ISO standard compliance
  • Color chart: a 20 patch color chart.

FAQs About  SFRPlus Test Charts

Ambient light, heat, and moisture levels should be regulated. The use of colored walls and reflective surfaces should be avoided, as they can damage the assessment of the sample colors visually.


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.

3nh Spectrophotometers for Paint Formulation 

For paint formulation accuracy, the 3NH top spectrophotometers prioritize high spectral resolution, excellent repeatability, superior inter-instrument agreement (IIA), d/8° integrating sphere design, and compatibility with advanced formulation software. Below are the leading models

  1. 3nh TS8560 Premium Benchtop Spectrophotometer  (Lab & R&D – Highest Accuracy)

    High precision with d/8° integrating sphere, excellent repeatability and inter-instrument agreement. Ideal for laboratory color analysis, accurate paint formulation and strict quality control. Perfect for opaque and translucent paints. Pairs seamlessly with Pecolor software for precise recipe calculation.

  2. Best for: High-end industrial coatings, R&D, and demanding formulation labs, High-volume paint labs, global color standardization

  3. 3nh TS7700 Portable Spectrophotometer

    Compact and easy to operate, supports SCI/SCE measurement. Perfect for on-site color matching, production line inspection and daily paint tinting control. Seamlessly connects to PeColor for on-the-go formulation, rugged, easy-to-use, designed for high-throughput retail environments.

  4. Best for: Retail paint stores, fast, accurate counter matching, On-site tinting, production line checks

  5. 3nh MS3008 Multi-angle Spectrophotometer

    Professional for metallic, pearlescent and special-effect paints. Captures angular color variation to meet high-end automotive and coating formulation requirements. Captures complex light behavior for perfect effect-paint matches.

  6. Best for: Automotive, specialty coatings


All these instruments deliver superior performance by measuring precise spectral data, which is the foundation for accurate, repeatable, and cost-saving paint formulation.

To operate the haze meter, first calibrate the instrument, clean the sample, position it correctly in the holder, and initiate the measurement. The instrument then shows the haze and overall transmittance readings.

The CCC is much like the CAC yet it frequently has advanced programmable lighting, sophisticated electronic control systems that allow for light source switching, and advanced visual testing.


A colorimeter or spectrophotometer should be used to measure the color of a solution. The instrument directs light through the liquid and quantifies absorbance at certain wavelengths. The values obtained indicate the color intensity of the solution and, by default, the concentration of the solution.
