An active stabilizied holographic setup for production of corrected concave gratings is decribed. Phase perturbations during exposure decrease diffraction efficiency. Two-wave interference at a holographic phase grating in a positive photoresist coated film is used for phase controlling during recording. The basic feature is the possibility of stabilization and resetting of the setup by the reference grating. Positive resist PFKL S-1 manufactured by VEB Foto-chemische Werke Berlin was used for recording deep grooves on plan and concave blanks.
