This Automotive Test Chart Instrument are Certified with

1 Years Warranty (Additional support period of 3 years)

This chart is designed for testing automative cameras or other significantly distorted cameras. This large chart is designed to be reflectively lit, and captured at a an optimal focus distance.

Options include:

  • Pre-distortion: Most automotive camera modules have significant fisheye distortion which can make it difficult to the outside of the image field. this chart has pincussion pre-distortion to approximately compensate for the barrel distiortion of the automotive camera module. The distortion coefficients that should be entered into the Imatest SFRplus settings window are [1.167 1.577]
  • Square Grid: 5x7 slanted square grid 
  • Substrate & ink type: Matte paper & ink can be used to reduce reflected light. This is critical for high levels of distiortion, otherwise specular reflections can ruin MTF measurements
  • Contrast levels: 10:1 contrast ratio, common for several automative testing standards
  • Color chart: a 20 patch color chart for color accuracy and bayer filter position verification
  • Bar to Bar height:  the maximum bar to bar height is 38.5 inches on the left and right side.  The minimum bar to bar height is 23.5 inches in the center.
  • Active Area: the extra-large chart be used for sensor sizes above 24 MP. This chart has an active area of 1500mm x 965mm and is printed on 1117 mm X 1524 mm inch paper

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.

FAQs About  SFRPlus Test Charts

SCI&SCE are two method in the color measurement. SCI means Specular Component Include,SCE means Specular Component Exclude.

Under the method of SCE, only test diffuse refection and exclude specular reflection. In that way, the test result is similar to object color was observed by human eyes.

Under the method SCI, both the diffuse refection and specular reflection will be included. In that way, the value about the color is more objective. It will not effect by the environment condition.

When we choose the instrument, those elements should be taking into consideration.


 Color is measured using devices such as colorimeters, spectrophotometers, and spectroradiometers. Colorimeters are easier and good for simple color quality tests. Whereas spectrophotometers yield detailed spectral information. Hence, suitable for laboratories and industries.

Spectrophotometer, Colorimeter, Gloss meter, Haze Meters, Coating thickness meter, window tint meter, UV meter, Leeb hardness tester, Light booth, Color Test Chart, Ultrasonic thickness gauge. Threenh Technology company adheres to independent design, research and development, production and sales of various measuring instruments. 

For a proper color evaluation, ensure cleanliness, use standardized observation conditions, eliminate stray light, and periodically change the lamps.


An 18% gray background reduces distractions and color bias, helping in a more accurate assessment.


Plastics, glasses, films, coatings, PET carboys，and packaging materials are common uses of hazemeter to monitor consistency and quality.
