Abstract
The invention relates to a lens reticle and a manufacturing method thereof. When light passes through the lens reticle of the invention, photopolymerization and divergence can be well carried out, and the image is amplified or reduced by utilizing the lens imaging principle, so that the structure of related optical instruments can be simplified, and the installation of a single lens is reduced.
Description
Technical Field
The invention relates to a lens reticle and a manufacturing method thereof.
Background
The existing reticle is a plane substrate, and the image cannot be directly magnified or reduced because the image is manufactured on the plane, and the complexity of related optical instruments is increased because instruments such as lenses are often needed.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a lens reticle and a manufacturing method thereof, which are used for endowing the reticle with the functions of zooming in and zooming out.
In order to solve the technical problems, the technical scheme of the invention is as follows:
a lens reticle comprises a transparent substrate, wherein the substrate is provided with a first surface and a second surface opposite to the first surface, the substrate is in a lens shape, and a reticle pattern layer is arranged on the first surface.
Further, the substrate is lenticular or concave.
Further, the thickness of the reticle layer is 50-500 nm.
The method for manufacturing the lens reticle comprises the following steps:
s1, polishing the surface of the substrate by a spherical polishing technology;
s2, plating a metal layer on the first surface by a vacuum coating technology;
s3, coating a photosensitive adhesive layer on the surface of the metal layer in S2;
s4, controlling the rotation of the substrate or the laser lens axis through five-axis processing equipment to complete exposure; then, etching is performed to obtain a division pattern layer.
Further, the vacuum coating technology is cylindrical target sputtering or curved surface evaporation.
Further, in S3, a photosensitive paste layer is coated on the surface of the metal layer by an ultrasonic spraying technique.
The base of the differentiation plate is lenticular and is a curved surface, and the pattern is made on the curved surface. Light can be well polymerized and diffused through the lens reticle, and the image is enlarged and reduced by utilizing the lens imaging principle.
In the invention, when light passes through the lens reticle, photopolymerization and divergence can be well carried out, and the image is amplified or reduced by using the lens imaging principle, so that the structure of related optical instruments can be simplified, and the installation of a single lens is reduced.

Detailed Description
The present invention will be described in detail with reference to examples. It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.
As shown in fig. 1, a lens reticle includes a transparent substrate 1, the substrate 1 having a first surface and a second surface opposite to the first surface, the substrate being lens-shaped, the first surface being provided with a reticle layer 2.
The substrate is in a convex lens shape.
The method for manufacturing the lens reticle comprises the following steps:
s1, polishing the surface of the substrate by a spherical polishing technology;
s2, plating a metal layer on the first surface by a vacuum coating technology;
s3, coating a photosensitive adhesive layer on the surface of the metal layer in S2;
s4, controlling the rotation of the substrate through five-axis machining equipment to finish exposure; then, etching is performed to obtain a division pattern layer.
The vacuum coating technology is cylindrical target sputtering.
And S3, coating a photosensitive adhesive layer on the surface of the metal layer by an ultrasonic spraying technology.
The first embodiment is repeated with the only difference that the basic body is modified to be concave lens-shaped, as shown in particular in fig. 2.
The foregoing examples are set forth to illustrate the present invention more clearly and are not to be construed as limiting the scope of the invention, which is defined in the appended claims to which the invention pertains, as modified in all equivalent forms, by those skilled in the art after reading the present invention.
