We are Moving!

Imatest is relocating to new office space in January 2021. We will minimize the impact to our customers, but we do anticipate longer lead times for order fulfillment. Our standard lead times will be suspended through the end of the February 2021 and will resume in March 2021. We will make every attempt to minimize the production downtime, but we cannot guarantee shipment of any new orders before this time. Our standard chart lead times can be found here: Shipping Policy.

Our new address will be 2525 Frontier Ave, Suite B, Boulder, CO 80301

Options include:

  • Pre-distortion:  Most automotive camera modules have significant fisheye distortion which can make it difficult to analyze the outside of the image field. this chart has pincushion pre-distortion to approximately compensate for the barrel distortion 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: 5 x 7 slanted square grid 
  • Substrate & ink type: Matte paper & ink can be used to reduce reflected light. This is critical for high levels of distortion, 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 977.9mm (38.5") on the left and right side. The minimum bar to bar height is 596.9mm (23.5") in the center.
  • Active Area: the extra-large chart be used for sensor sizes above 24mp. This chart has an active area of 1500mm x 965mm (59.05" x 37.99") and is printed on paper measuring 1117mm x 1524mm (43.98" x 60").

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.
