Abstract
A micro-lens array and manufacturing method. A hybrid micro-lens in which a refractive lens and a diffraction lens are formed includes: a refractive lens; a first ultraviolet hardening material which is bonded on a curved surface of the refractive lens to form an aspheric surface; a support substrate including a concave portion into which the refractive lens is inserted and supported; and a diffraction lens which is formed at a position corresponding to the refractive lens disposed on the support substrate.
Claims14
A method of manufacturing a micro-lens array, comprising:
- (a) forming at least one cavity on a substrate;
- (b) injecting a first ultraviolet hardening material into the cavity and positioning a lens on the first ultraviolet hardening material;
- and
- (c) coating a second ultraviolet hardening material on the lens and a surface of the substrate, positioning a transparent plate on the second ultraviolet hardening material, and irradiating an ultraviolet ray while pressing the second ultraviolet hardening material, thereby hardening the first and second ultraviolet hardening materials.
