The TC-R4K chart is an enhanced version of the ISO 12233:2000 test chart, designed for resolving power testing of digital cameras. It supports signal output up to 4000PW/PH (line widths per picture height, equivalent to ~24MP cameras) for both monochrome and color cameras. The center wedge pattern reaches 4000PW/PH, while corner wedges achieve 2000PW/PH. Added low-contrast slanted edges enable precise SFR curve measurement.

Product Highlights
1. Multi-Functional Patterns
"F" and "C" frames: Viewfinder and focus calibration
"H" wedges (6 center + 4 corner patterns): Visual resolution analysis
"S" pattern: Horizontal and vertical resolution limit and visual "sharpness" are measured (according to loss of contrast at high frequencies)
"O" pattern (5° tilt): Aliasing measurement
"G" pattern: Detail reproduction and sharpening evaluation
"M" radial pattern: Scanning linearity test
"N" checkerboard: Compression artifact detection
"E" line (1.5° tilt): Staircase effect analysis
"L" and "P" edges: High/low-contrast SFR (software required)
"Q":Full-field resolution assessment
2. Imaging Test Applications
Static camera resolution measurement
Spatial Frequency Response (SFR) analysis
Camera module sharpness testing
