Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for manufacturing a resin-bonded optical element.

[0002]

2. Description of the Related Art A lens which is an optical element includes an aspherical lens having an aspherical surface. Aspherical lenses are frequently used because they can remove spherical aberration due to spherical lenses and distortion in wide-angle lenses. At present, there is a resin-bonded aspherical lens as an aspherical lens having excellent mass productivity. This lens is composed of a thin (for example, 5 to 100 .mu.m thick) resin cured layer 12 and a lens 11 as a base as shown in FIG.

[0003] In the lens of FIG.
Has a spherical surface, and the resin cured layer 12 is joined on the spherical surface with a thickness distribution so as to form an aspherical surface. Such a resin-bonded aspherical lens is manufactured by, for example, a manufacturing method shown in FIG. FIG. 4 is a process chart showing a conventional method for manufacturing the resin-bonded aspherical lens shown in FIG.
In the following description of the steps, the numbers in parentheses correspond to steps (1) to (4) in FIG.

(1) A mold 13 having a predetermined surface shape (a flat surface, a spherical surface, an aspherical surface, etc.) is placed horizontally, and a predetermined amount of a photo-curable resin liquid 12a is dropped at the center of the surface. (2) Lower the lens substrate 11 toward the mold 13;
By bringing the substrate 11 close to the mold 13, the resin liquid 1
2 a is pushed out in the gap between the base material 11 and the mold 13.

Here, as the material of the substrate 11, glass or a crystalline optical material is used. (3) The lens base 11 and the mold 13 are brought close to each other such that the distance between them becomes a predetermined value. In this state, light (ultraviolet rays) 14 is irradiated to the resin liquid 12a through the base 11. The resin liquid 12a is cured by a polymerization reaction to form a cured resin layer 12.

(4) The cured resin layer 12 integrated with the lens substrate 11 is peeled off from the interface with the mold 13. The resin-bonded aspheric lens can be obtained by the above-described manufacturing method (step). When an aspheric lens is manufactured by such a method, the approach between the lens substrate and the mold is generally controlled by the distance (interval) between the substrate and the mold, and when the distance (interval) reaches a predetermined value, the two approaches. Stop approaching.

[0007]

However, the reproducibility of the dripping amount of the photocurable resin liquid dripping at the center of the mold surface is poor, and the dripping amount of the resin liquid varies even when dripping under the same conditions. In such a state, when the lens substrate and the mold are brought close to each other to a predetermined distance, the spread of the resin liquid increases when the amount of the resin liquid dropped is large, and when the amount of the resin liquid dropped is small, the resin liquid spreads. Spread is reduced.

If the spread of the resin liquid is too large, an aspherical lens having an outer diameter larger than the designed shape is produced, so that the produced lens cannot be incorporated into the optical system. If the spread of the resin liquid is too small, there is a problem that an aspheric lens having desired optical characteristics cannot be obtained.

That is, if the spread of the resin liquid is too large or too small when manufacturing the resin-bonded aspherical lens, the manufactured aspherical lens becomes defective and the non-defective product ratio decreases. Occurs. The present invention has been made in view of such a problem, and it is possible to set a spread of a resin liquid when manufacturing a resin-bonded optical element within a predetermined range. It is an object of the present invention to provide a method and apparatus for manufacturing a resin-bonded optical element that can significantly increase the yield of optical elements.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the manufacturing method according to the present invention (claims 1 to 6), a photo-curable resin liquid dropped on the surface of a mold or the surface of an optical element substrate is treated with a substrate and a mold. When the resin liquid is pressed and spread from the center to the peripheral portion in a predetermined range in the gap, the resin liquid is irradiated with light to be cured, so that the cured resin layer and the base material are integrated.

Therefore, according to the present invention (claims 1 to 6), a resin-joined optical element having an outer diameter larger than a designed shape due to too large spread of the resin liquid is manufactured, and the manufactured resin-joined optical element is manufactured. Manufacturing without the problem that the optical element cannot be incorporated into the optical system, and the problem that the spread of the resin liquid is too small to obtain a resin-bonded optical element having desired optical characteristics does not occur. The non-defective rate of the resin-bonded optical element to be manufactured can be remarkably increased.

A manufacturing apparatus according to the present invention (claims 7 to 10) is an apparatus capable of performing the manufacturing method according to claims 1 to 6, and similarly, a resin-bonded optical element manufactured by the apparatus. Can be remarkably increased. That is, according to the manufacturing method or the manufacturing apparatus according to the present invention (claims 1 to 10), it is possible to set the spread of the resin liquid in manufacturing the resin-joined optical element to a predetermined range. The non-defective rate of the manufactured resin-bonded optical element can be significantly increased.

The present invention observes the spread of the resin liquid which is spread by the approach of the optical element substrate and the mold. For example, when the diameter of the resin liquid falls within a predetermined range, the optical element substrate and the mold are separated. Stop approaching and hold this state, light (ultraviolet light)
And the apparatus for irradiating the resin liquid through the optical element substrate. Thus, in the present invention, the spread of the resin liquid is observed, for example, when the diameter of the resin liquid is within a predetermined range, the approach between the optical element substrate and the mold is stopped,
Since the resin liquid is cured, the diameter of the resin layer does not deviate from a predetermined range when the resin liquid is spread.

On the other hand, in the conventional method of manufacturing a resin-bonded optical element, the distance (interval) between the mold and the optical element substrate is controlled when the resin liquid is spread, which is a result. In other words, the thickness of the cured resin layer is controlled. Therefore,
In the conventional manufacturing method, the diameter of the formed cured resin layer is
This varies depending on the amount of the resin liquid supplied at the time of manufacture, and causes the above-described problems (cannot be incorporated in an optical system, and desired optical characteristics cannot be obtained).

In the present invention, since the spread of the resin liquid is controlled so as to be within a predetermined range, the thickness of the cured resin layer slightly varies. However, the tolerance of the resin layer thickness, which is determined by the optical performance required for the optical element and the dimensional tolerance when the optical element is incorporated into an optical system (for example, a lens in a housing), is determined by the spread of the resin liquid. That is, it is larger than the allowable tolerance of the cured resin layer formation region).

Therefore, according to the present invention, a resin-bonded optical element can be manufactured within an allowable tolerance of the thickness of the resin layer even if the amount of the resin liquid supplied at the time of manufacture slightly varies. In the gap between the optical element base material and the mold, as the resin liquid detection portion of the present invention for detecting the spread or the end position of the resin liquid pushed out from the center toward the peripheral portion, for example, the spread of the resin liquid Alternatively, a moving image camera that captures an image of the end position, an image processing device that performs image processing on image data of the spread of the resin liquid or the end position, or the like can be used.

In the invention according to claims 4, 6, 9 and 10, the optical element substrate coated with the resin liquid is turned over, and the resin liquid on the substrate surface (downward) and the die surface ( (Upward) contact. With this configuration, the contact area when the resin liquid and the mold surface first come into contact with each other is integrated and does not form a plurality of islands, so that air bubbles are not involved. Therefore, it is preferable because a cured resin layer without bubbles is obtained.

Hereinafter, the present invention will be described more specifically with reference to examples, but the present invention is not limited to these examples.
