4000 Lines Resolution Test Chart ISO12233 Image Test Card for High Precision Imaging Devices Using Photolithographic White Film
The ISO 12233 4000-line chart is an enhanced resolution test target that complies with the ISO 12233 standard. It is primarily engineered for evaluating the clarity and resolution performance of high-precision imaging devices.
Building upon the standard 2000-line test chart, this enhanced version incorporates a star pattern and 5° oblique edge elements, extending the resolution measurement range to 500–4000 lines per image height.
- Central area: Supports resolution measurement up to 4000 lines.
- Edge area: Supports resolution measurement up to 2000 lines.
- Coverage: Meets the demanding testing requirements of high-pixel imaging devices.
