Long-working-distance phase-measuring deflectometry (LWD-PMD) in a 2f configuration requires high accuracy over large working distances, placing particular demands on system calibration. This work addresses the gray-value and geometric calibration of such a setup and presents results of an in-situ pointspread-function estimation for the astronomical mirror under test.
