Abstract

PURPOSE:To obtain inexpensively an optical part good in accuracy of the surface, by providing a photo-setting resin layer on a plastic substrate surface, and a releasing agent layer on a surface of a matrix for an optical part, bringing the layers into firm contact with each other, irradiating an activation energy beam on the photo-setting resin layer, and separating the matrix at the releasing agent layer from the substrate. CONSTITUTION:A photo-setting resin (e.g. an ultraviolet-curing resin, etc.) layer 2 is formed on the surface of a plastic substrate 1 (e.g. a polymethyl methacrylate resin, etc.), and after the releasing agent (e.g. a polydimethyl siloxane, etc.) layer 4 is formed on the surface of the matrix 3 for the optical part to be duplicated, the photo-setting resin layer 2 and the releasing agent layer 4 are brought into firm contact with each other. Then an activation energy beam (e.g. ultraviolet beam, etc.) is irradiated to set the photo-setting resin layer, and the matrix 3 is separated with the aid of the releasing agent layer 4 from the plastic substrate 1 to obtain the intended optical part.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing an optical component, and particularly to a method of manufacturing an optical component using a replica method.

Conventional optical component manufacturing methods have utilized injection molding, compression molding, and the like when, for example, plastic is used as the material or substrate of the optical component. However, although these manufacturing methods are inexpensive, the more complex the shape of the optical component, the worse the transferability from the mold, and the more difficult it becomes to obtain the required optical characteristics. In particular, when trying to obtain a plane such as the anti-fJ=J plane, depending on the conditions,
No matter how good the surface area of the molding IUL is, it is often not possible to faithfully reproduce the surface area due to sink marks and the like.

Another manufacturing method is the prototype method for optical components, i.e., the replica method in which the shape of the matrix is transferred to the substrate, but since this uses a glass as the substrate, the shape of the optical component becomes complex. The disadvantage is that the cost increases accordingly.

The purpose of this invention is to make inexpensive glass plastic.
．． This invention aims to provide an optical component manufacturing method using the replica method. /1-Mold the Plus Deck material into a shape similar to a medical part by injection molding or the like.1. Li2<Toji, that”-

It is characterized in that it is hardened without being formed into the shape of J, and j'++ K'' is darkened by 1 and then converted to Gakubu Kaneko II.

Hereinafter, an example of the present invention will be explained with reference to FIG. 1. First of all, take a mold for injection forming force f with a surface-finished metal or glass material into a molding machine, and f-1 is filled with acrylic resin/,
The parts are injected and molded one by one to become optical parts. The base 1 of this optical component has a surface roughness 19, and a Jt:filJl-forming resin layer 2 is applied to the surface.

1. Formed by optical polishing of metal, glass, etc., a release agent layer 4 is applied to the surface of the material, which is coated and sprayed 1.
It is preferable that at least one of the plastic substrate 1 and the tiJ-type filter be formed of a translucent coating material. Then, as shown in FIG. 1 (81), the photocurable resin layer 2 and the mold release agent layer 4 are stacked so that they are in close contact with each other, and active energy rays 5 such as ultraviolet rays are applied to the photocurable resin layer 2. Be sure to irradiate the light toward the target.This will cause the thin photocurable resin layer 2 to become l;
J]-143.

Then, if the plastic base 1 and the IU mold 5 are bonded via the mold release agent layer 4, the result will be as shown in FIG. 1 (C+).

? An optical component with a high degree of surface area is produced by turning the AI fat layer 2. Rabbit, if a transparent thin film layer is provided on the "-" of the Mochi 1 type agent layer 4 of Figure 1 +A+, the photocurable resin layer 2 of the finished γ-ri 11 product will be covered by this thin film layer. A film will be formed.

The plastic substrate 1 can be formed by injection molding, compression molding,

Vitrifying monomers that are cured by γ rays such as methacrylic acid esters, and those that are polymerized and cured by non-human radiation and electron beams can also be used.

As the mold release agent 4, a silicone-7 type oil in the form of polydimethyllogisan kJE can be used.

The method according to the present invention can be applied to all kinds of electrical components, or if a reflective film is provided on manufactured products by direct air deposition, it can be applied to a four-microphone mirror array as shown in Figure ff12.
