1X - I3A/ISO 12233 Resolution Test Chart, #56-074
1X - Enhanced I3A/ISO 12233 Digital Camera Resolution Test Chart, #58-940
This target is designed to test resolution of electronic still picture cameras, and complies with ISO 12233. Both monochrome and color cameras delivering an analog or digital output can be used with this test chart. The target can be employed to measure visual resolution, limiting resolution, and offers a simple method in obtaining spatial frequency response (SFR) data, which is similar to that of MTF measurements for a camera. Features on the chart range from 100 to 2000 LW/PH (line widths per picture height), which corresponds to the finest feature being 0.1mm. This test chart is offered in three sizes to accommodate a variety of cameras and lenses.
The 1X and 2X Enhanced Digital Camera targets are based on the ISO-12223 chart but have additional information. They can be used to determine reflective light resolution and imaging characteristics of digital still camera systems.
