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.
