CP198-TI

120dB Gray Scale Transmissive Test Chart (20 Patch)

The CP198-TI dynamic range test chart features a central polarizer compliant with ISO 14524/15739 standards. With 20×20mm grayscale blocks arranged in a ring pattern and 1,000,000:1 contrast, it enables precise noise, SNR, and dynamic range testing, especially for auto-exposure camera calibration.

Quick Specifications
  • Polarizer Compensation: Eliminates 92% of auto-exposure errors
  • Ring Pattern Design: 20 calibrated blocks reduce shadow interference
  • ISO Compliance: Fully supports ISO 14524 testing protocols
