The invention relates to a gray scale inscribing method and device, computer equipment and a storage medium. Determining an incident light spot of the grating light valve according to a laser beam emitted by the laser light source; performing phase modulation on the incident light spot through a subunit of the grating light valve, and determining a first-order diffraction light field of the subunit; determining an inscribing line light field according to the first-order diffraction light field of the subunit; driving the inscribing line light field to rotate through a Dove prism, and determining a rotating light field; determining a target light intensity distribution gradient of the inscribing line light field according to a curved surface structure of a micro lens; and according to the rotating light field, the inscribing line light field and the target light intensity distribution gradient, gray scale inscribing is carried out on the micro lens. According to the method, the machining efficiency of the micr
