Abstract: A method for manufacturing a multi-stage compound eye lens includes the steps of manufacturing a micropillar array using a photoetching method, then sputtering ZnO on the surface of the micropillar array, jet printing an ultraviolet curing adhesive onto gaps in the micropillar array using a micro jet printing machine, and controlling the morphology of microlens using the number of droplet dropping instances to obtain a microlens array; further respectively dissolving hexamethyl tetramine and zinc nitrate in deionized water, then pouring the hexamethyl tetramine solution into the zinc nitrate solution to obtain a mixed solution, placing the microlens array into the mixed solution, and placing is in a water bath kettle for a water bath, and finally, removing the microlens array from the mixed solution, rinsing it with deionized water, and drying same to obtain the multi-stage compound eye lens.
