In the paper a new off-axis achromatic interferometer configuration of a digital holographic microscope is presented. The proposed configuration uses a reflective diffraction grating and ensures a high-contrast interference pattern in the output plane of the microscope using illumination of an arbitrary degree of temporal and spatial coherence. The concept of this optical system brings a significant improvement of microscope parameters, enables implementation of conventional observing techniques and is more user-friendly in comparison with the previous generation of the microscope. The functionality of the microscope has been proved experimentally.
