Embodiment Construction

[0029] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0030] A method for manufacturing a microlens array, comprising the following steps,

[0031] S1: Design and generate the required microlens array model, and set the corresponding laser power, laser beam spot size and laser dwell time according to the parameters of the required microlens array;

[0032] S2: Provide a clean substrate and make a dimple array on the substrate by laser dotting;

[0033] S3: Coating the silicone rubber prepolymer evenly on the surface of the micro-concave array, preparing a silicone rubber micro-convex lens array after curing and separating, and performing polishing treatment.

[0034] In the step S3, the silicone rubber micro-convex lens array is transferred to a substrate to prepare the micro-convex lens array of the substrate.

[0035] The described silicone rubber micro-convex lens array is transferred t...

Abstract

The invention relates to a manufacturing method of micro-lens arrays. The manufacturing method of the micro-lens arrays includes the first step of designing and generating a model of the needed micro-lens arrays and setting corresponding laser power, the size of a laser beam spot and laser duration of stay according to parameters of the needed micro-lens arrays, the second step of providing a clean substrate and manufacturing micro-concave arrays on the substrate according to a laser spotting method, the third step of evenly coating silicone rubber pre-polymers to the surfaces of the micro-concave arrays and manufacturing silicone rubber micro-lens arrays after solidification and separation, the fourth step of transferring the silicone rubber micro-lens arrays to other materials and manufacturing the micro-lens arrays made of different materials, and the fifth step of carrying out polishing processing on the micro-lens arrays later. By the utilization of the method, the high-accuracy and large-area micro-lens arrays can be manufactured, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of micro-nano processing and manufacturing, in particular to a method for manufacturing a micro-lens array. Background technique [0002] Microlens array refers to an array formed by a series of microlenses with a diameter between several microns and several millimeters arranged in a certain way, which can realize the focusing, emission, deflection, division, recombination, switching, coupling, receiving, etc. of light beams. It is one of the important components of the micro-optical system and is widely used in naked-eye stereoscopic display, beam shaping, fiber coupling and other fields. At present, the manufacturing methods of the microlens array mainly include: (1) A metal mold is prepared by a mechanical method, and then the microlens array is prepared by an inverted mold method. The microlens array prepared by this method has high precision and can prepare a large-area microlens array, but the disadva...
