Optical imaging element and manufacturing method thereof

Abstract

The present invention discloses an optical imaging element and a manufacturing method thereof. The optical imaging element is mainly formed by an upper layer of a light transmission stacked body and alower layer of a light transmission stacked body which are formed by binding of a plurality of long and thin transparent bars plated with single-sided or both-sided metal reflection layers, directions of the internal reflection surfaces of the two light transmission stacked bodies form an orthogonal array, and the upper layer of the light transmission stacked body and the lower layer of the lighttransmission stacked body are glued through a transparent macromolecule adhesive. The manufacturing method comprises the steps of: plating of a metal reflection layer, cutting of transparent materials, bonding of the long and thin transparent bars, forming and polishing of the light transmission stacked bodies and forming of the optical imaging element. The optical imaging element is simple in structure and has a good optical imaging performance, the manufacturing method of the optical imaging element is simple in production process and low in production cost, and compared to a manufacturingmethod in the prior art, a lot of manpower and material resources can be saved, and low-cost batch production of optical elements can be achieved.

Description

technical field [0001] The invention belongs to the technical field of optical imaging, and in particular relates to an optical imaging element and a manufacturing method of the optical imaging element. Background technique [0002] The optical imaging element is the basic unit of the optical system, and most of the optical imaging elements play the role of imaging, such as lenses, prisms or mirrors. In addition, there are some optical imaging components that play special roles in the optical system, such as light splitting, image transmission and filtering, such as reticles, filters, gratings or optical fiber components. Holographic lenses, gradient index lenses, and binary optical elements are new optical imaging elements that have emerged in the past ten or twenty years. The optical imaging elements in the prior art are manufactured by evaporating metal reflective surfaces on the surface of optical plates such as transparent synthetic resin plates or glass plates. This m...
