We are Moving!

Imatest is relocating to new office space in mid December. 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 year and will resume in January, 2021. We will make every attempt to minimize the production downtime, but we cannot guarantee shipment of any new orders before year-end. If you need to meet year-end budgetary requirements, please contact us so that we can discuss possible options. Our standard chart lead times can be found here: Shipping Policy.

Effective December 15, 2020, our new address will be 2525 Frontier Ave, Suite B, Boulder, CO 80301

ISO 12233: Ver. QA-77 Enhanced digital camera resolution chart


Please Note

This chart does not conform to the updated ISO 12233:2014 standard. We recommend the Photographic ISO 12233:2014 E-SFR chart for testing that does not specifically require the old chart.

Based on ISO 12233:2000, the QA-77 has all of the original features as the QA-72 plus several new ones, such as; Star Sector target; 5° slant bar; 5° dark gray square for SFR analysis as well as a greater resolution range, from 100 - 4000 Line Width / Pixel Height and hyperbolic wedges.

Note: This chart has a 2-4 week lead time.
Our product pricing and shipping rates do not include import duties, taxes or fees. The customer / recipient is responsible for these expenses.

ISO 12233: Ver. QA-77 Enhanced digital camera resolution chart




Notes: QA-77-4-P-RM will not contain gray features, it will consist of black and white line work only.

This chart is used to measure sharpness from slanted-edge patterns (as Spatial Frequency Response = SFR) using the Imatest SFR module. It can also measure resolution from the hyperbolic wedges using the Imatest Wedge module (a part of Rescharts).
