The invention concerns a hybrid simulator (100) for teaching optics or for training adjustment of an optical device. According to the invention, the hybrid simulator (100) comprises at least one dummy optical component (10) physically simulating an optical device, at least one actuator device (30) for generating or simulating an adjustment of said dummy optical component (10), a sensor configured for detecting an adjustment signal representative of operating said actuator device (30), a digital processing system (90) comprising a numerical model for simulating an output numerical optical beam resulting from interaction between an input numerical optical beam and a numerical optical component representing said optical device as a function of said adjustment signal and a display system (2, 95) for displaying a visual signal (51, 52) representative of said output optical beam and/or augmented reality signals (60, 61, 62, 63).
