Title:
METHOD FOR MANUFACTURING MULTI-STAGE COMPOUND EYE LENS
Document Type and Number:
WIPO Patent Application WO/2021/143148
Kind Code:
A1
Abstract:
Disclosed is a method for manufacturing a multi-stage compound eye lens, the method involving: first 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 microlenses 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 same in a water bath kettle for a water bath; and finally, removing the microlens array from same, rinsing same with deionized water, and drying same to obtain the multi-stage compound eye lens. Where the optical signal crosslinking is reduced, the structure surface hydrophobicity and the droplet stability can be improved to a great extent; the droplet stability is greatly improved, and it is difficult for droplets to fill the gaps in the micropillar array; and the nanostructure of the gaps between the microlenses can reduce the light transmittance and reduce crosslinking between optical signals.
