ISO 12233 / eSFR test chart
Works with image-quality analysis workflows to measure spatial frequency response, resolving power, and imaging sharpness.
ISO 12233 / eSFR test charts
Custom ISO 12233 and eSFR test charts
Custom ISO 12233, eSFR, and combined imaging charts for camera modules, lenses, and security-imaging quality evaluation. Chart version, analysis software, size, and optical mode are confirmed before production.
Start from the use case
The chart must match the whole analysis workflow
An ISO 12233 or eSFR chart is part of a test system, not an isolated picture. First define whether the workflow measures resolving power, SFR, sharpness, color, grayscale, or focus, then set the layout around the software, distance, and light source.

- Camera-module and lens resolution evaluation
- Spatial-frequency response and sharpness analysis
- Security-camera image-quality acceptance
- Combined color, grayscale, clarity, and focus tests

Technical confirmation
ISO 12233 / eSFR chart confirmation path
- 01
List the metrics first
Separate resolution, SFR, sharpness, color, grayscale, dynamic range, and focus requirements.
- 02
Lock revision and software compatibility
Record the chart revision, analysis software, and calculation method so similar-looking charts remain comparable.
- 03
Set the layout by field of view
Use the camera field of view, capture distance, and workspace to set chart size, margins, and combined regions.
- 04
Confirm optical mode and delivery
Set reflective or transmissive mode, surface treatment, packaging, quantity, and report requirements before production.
FAQ
ISO 12233 / eSFR chart questions
Can an ISO 12233 chart and an eSFR chart be used interchangeably?
Do not assume that they are interchangeable. Revision, pattern, software, and metric definitions can differ, so the chart type should follow the existing test workflow.
Can the chart support camera-module acceptance testing?
Yes, as part of an image-quality acceptance process. Capture distance, light source, software, thresholds, and report format should be fixed for batch-to-batch comparison.
Can multiple test items be combined on one chart?
They can be discussed, provided the size, illumination, and analysis areas do not interfere with one another. The layout follows the test workflow.
Chart revision, pattern combination, dimensions, optical mode, and delivery parameters are governed by the technical confirmation sheet.
