An ISO 12233 and IEEE-CPIQ P1858 compliant, low-contrast chart that delivers radial sagittal & tangential MTFs at different positions. Analyzer software calibrates the MTF measurement from the chart resolution.
The MTF chart lets you use Analyzer software to autonomously obtain all objective metrics. We calibrate Analyzer software to remove the chart resolution from the MTF measurements, and we test every composite chart in our labs before shipping to ensure the same results between two charts. We also assign each chart a unique identification number to facilitate high traceability.
