The invention discloses a substrate, an optical module, an optical calibration device and a calibration method. The substrate comprises a frame body; the movable block is located in the frame body, and the movable block is used for fixing the optical assembly; one end of each cantilever beam is connected with the frame body, and the other end of each cantilever beam is connected with the movable block; the adjusting piece is installed on the frame body, and one end of the adjusting piece extends into the frame body and abuts against or is connected with the movable block; wherein the adjusting piece is used for driving the movable block to move, and the cantilever beam is used for providing resilience force for the movable block through self deformation. When the optical assembly needs to be moved, the adjusting piece pushes the movable block, when the movable block moves, the cantilever beam deforms, when the acting force of the adjusting piece is removed, the movable block drives the optical assembly to ret
