ISO 144909 is the ninth part of the ISO 14490 series that discusses optics and photonics. ISO 144909 specifies the test method for the determination of the deviation from a flat image surface, i. e., the sagittal and tangential field curvature of telescopic systems and observational telescopic instruments.
