Measurement data for "Off-Axis, slit based MTF measurements at PTB"

The provided data enable the immediate replication of the results presented in "Off-Axis, slit based MTF measurements at PTB." The research data are structured with respect to the figures presented in the proceeding. The subfolder "MTF_Fieldscan_measurement_data_pm20_deg_pm40um_10repetitions" contains all necessary measurement data to receive the figure from the contribution by running a MATLAB file. Therefore, it is possible to compare the results with full context to those presented in the contribution. The measurement data saved as *.mat files contain the mean over multiple pixel rows of the line spread function (LSF) as recorded by the camera detector and the associated modulation transfer function (MTF) which is calculated as described in the conference proceeding. The specimen under test is a calibration objective manufactured by Zeiss with infinite to finite imaging, a focus distance of f_s = 50mm and an f-number a_s = 4. The following abbreviations are employed in the labeling of the subfolders: pm -> Plus/Minus deg -> degree um -> micrometer
