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

SKU: QA-77-X-P-RM

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.

Availability: In stock

Details

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).
