  Embodiments of the present invention will be described in detail with reference to the drawings. In the present embodiment, a method of forming a protrusion for correcting aberration with respect to an objective lens using a resin in an optical pickup as an optical device will be described. FIG. 1 shows a conceptual diagram of an optical pickup having a lens in this embodiment. As shown in this figure, the optical pickup includes a lens 1 disposed so as to face the recording medium 6, a light emitting unit 2 made of a semiconductor laser that emits light toward the lens 1, and light from the lens 1 side. A light receiving unit 3 that receives light, a beam splitter 4 that causes light from the light emitting unit 2 to enter the lens 1 and light from the lens 1 to the light receiving unit 3, and a mounting base 5 that holds and fixes the lens 1 are provided. Configured.

  In the optical pickup, light from the light emitting unit 2 is incident on the lens 1 through the beam splitter 4, and is converged light by the lens 1 and applied to the recording medium 6. Reflected light from the recording medium 6 is bent by the beam splitter 4 through the lens 1 and incident on the light receiving unit 3 to read information recorded on the recording medium 6.

  FIG. 2 shows a perspective view of the lens 1. As shown in this figure, the lens 1 is provided with a lens surface 10 as an optical function part formed in the shape of a convex lens, and a collar part 11 is formed around the circumference thereof. The lens 1 is made of a transparent glass material, and is formed by pressing a heated and softened material with a molding die and transferring the shape of the molding die.

  The flange portion 11 has a flat mounting surface 12 that substantially faces in the optical axis direction. The mounting surface 12 constitutes an outer peripheral side portion with respect to the peripheral portion of the lens surface 10 and has a ring shape by being flat over the entire periphery of the lens 1. The mounting surface 12 becomes a reference surface for mounting on the optical pickup by being placed on the mounting base 5 of the optical pickup.

  Projecting convex portions 13 are formed at three locations on the mounting surface 12. The top part of the convex part 13 is made into a flat planar shape and constitutes the contact surface 14. Since the convex portion 13 is formed on the mounting surface 12, three-point support is provided by the contact surface 14 of the convex portion 13 when the lens 1 is placed on the mounting base 5 as will be described later, and the lens 1 is placed in a predetermined direction. Can be tilted. The protrusions 13 are arranged such that the triangle connecting the protrusions 13 on the mounting surface 12 forms an isosceles triangle, and one protrusion 13a constituting the apex angle is composed of two protrusions constituting the base angle. It is higher than 13b and 13c, and the lens surface 10 is inclined so as to become higher toward the convex portion 13a by being placed on the mounting base 5. Further, each convex portion 13 is arranged so that the apex angle of the isosceles triangle formed by the three convex portions 13 faces the coma aberration correction direction.

  FIG. 3 shows a side view of the lens 1 placed on the mount 5. As shown in this figure, the lens surfaces 10 of the lens 1 are formed on both surfaces, and in the optical pickup, a first surface 10a disposed on the light emitting unit 2 side and a second surface disposed on the recording medium 6 side. It consists of surface 10b. The first surface 10a is formed to protrude larger than the second surface 10b, and in FIG. 2, the lens surface 10 facing upward is the first surface 10a.

  The mount 5 of the optical pickup is formed so that a portion where the lens surface 10 is disposed is a space and the upper surface 5a is flat, and the mounting surface 12 of the lens 1 is placed on the upper surface 5a. can do. Here, as described above, the mounting surface 12 of the lens 1 has convex portions 13 formed at three locations, and the heights thereof are different, so that the mounting surface 12 is placed on the upper surface 5 a of the mounting base 5. As a result, the lens 1 is inclined in one direction. The inclination direction and the inclination angle are set so as to correct the coma aberration of the lens 1, and the convex portion 13 is formed so as to have the setting direction and angle.

  Next, the manufacturing method of the lens 1 in this embodiment is demonstrated. In FIG. 4, the conceptual diagram of the process of shape | molding the lens 1 is shown. As shown in this figure, when the lens 1 is manufactured, it is necessary to prepare a metal mold 20 in advance. The molding die 20 includes two upper and lower molds, and a lens molding surface 20a having a shape obtained by inverting the lens surface by cutting and grinding is formed.

  As shown in FIG. 4A, a glass material 21 softened by heating is placed on the mold 20. Next, as shown in FIG. 4B, the two opposing molds 20 are brought close to each other, the glass material 21 is pressed, and the shape of the lens molding surface 20 a is transferred to the glass material 21. When the lens surface 10 is formed in this manner, the glass material 21 is cooled and cured to form the lens 1 having the lens surface 10 and the flange portion 11. When the glass is cured, the lens 1 is released from the mold 20 and taken out.

  Once the lens 1 is formed, the coma aberration direction and magnitude of the lens 1 are then measured. For the measurement of coma aberration, any method including a diffraction interference measurement method using optical interference may be used. When the coma aberration direction and magnitude are measured, it is desirable to mark the attachment surface 12 at an arbitrary position so that the coma aberration correction direction can be understood. By measuring the magnitude of the coma aberration, the angle at which the lens 1 should be tilted is calculated.

  In FIG. 5, the conceptual diagram of the formation process of the convex part 13 is shown. First, as shown in FIG. 5A, an adhesive material 22 made of a resin material is applied to three locations on the attachment surface 12 of the flange portion 11. The adhesive 22 used here has a characteristic of being in a semi-cured state having elasticity when irradiated with ultraviolet rays in a liquid state and being completely cured by irradiating with ultraviolet rays. As an adhesive material, for example, Kyoritsu Chemical Industry Co., Ltd. WORLD ROCK 8723K9C, an epoxy resin, an acrylic resin, a urethane resin, a silicone resin, a polyimide resin, or the like can be used. It can be. In FIG. 5A, the adhesive 22 is in a liquid state and can be easily applied to the mounting surface 12.

  In a state where the adhesive material 22 is applied to the mounting surface 12, the adhesive material 22 is irradiated with ultraviolet rays as shown in FIG. In the semi-cured state, the adhesive 22 can be deformed by pressing. Subsequently, as shown in FIG. 5C, the transparent plate 23 is covered from the first surface 10 a side of the lens surface 10. The transparent plate 23 is made of a transparent material such as acrylic, and is provided with a hole 23 a so as not to interfere with the lens surface 10.

  The transparent plate 23 is disposed to be inclined with respect to the lens 1. The inclination is adjusted to be an angle necessary for correcting the coma aberration of the lens 1. When the surface of the transparent plate 23 approaches the mounting surface 12 of the lens 1, the transparent plate 23 contacts the semi-cured adhesive 22 on the mounting surface 12. Further, when the surface of the transparent plate 23 is brought close to the mounting surface 12, the semi-cured adhesive 22 is pressed by the transparent plate 23 and its height changes. At this time, since the adhesive 22 is in a semi-cured state and not in a liquid state, the adhesive 22 does not flow on the mounting surface 12 and the transparent plate 23 is adjusted so as to be close to the mounting surface 12, In any case where the adjustment is performed so that the transparent plate 23 is moved away from the mounting surface 12, the shape of the adhesive 22 can be deformed following the shape. That is, the adjustment of the transparent plate 23 can be performed in any of the three axes of x, y, and z.

  As shown in FIG. 5D, after adjusting the transparent plate 23, the adhesive 22 is irradiated with ultraviolet rays through the transparent plate 23. As a result, the adhesive 22 is completely cured, and the convex portion 13 is formed. Since the transparent plate 23 is inclined with respect to the mounting surface 12 as described above, the convex portion 13 is formed to have a different height. Finally, as shown in FIG. 5E, the lens 1 having the convex portion 13 is completed by removing the transparent plate 23. In addition, it is desirable to perform surface treatment in advance so that the adhesive does not adhere to the surface of the transparent plate 23 so that the transparent plate 23 and the convex portion 13 are not in an adhesive state as the adhesive 22 is cured.

  According to the resin molding method using such a semi-cured state of the adhesive, the resin is in a liquid state at the time of application, and the resin is in a semi-cured state when adjusting the height. When the step is performed, a resin protrusion having a predetermined height can be easily formed by a step of fully curing the resin. Moreover, although the convex part 13 for correcting the coma aberration is formed in the present embodiment, the molding method of the present embodiment can be used even when a projection used for other purposes is formed. .

  Next, a second embodiment of the present invention will be described. In this embodiment, a method for positioning and fixing an objective lens in an optical pickup as an optical apparatus will be described. Since the optical pickup of this embodiment has the same configuration as that of the first embodiment, description of the configuration is omitted.

  In FIG. 6, the conceptual diagram of the process of positioning and fixing the lens 1 in this embodiment is shown. As shown in FIG. 6A, an adhesive 22 made of a resin material is applied to the mounting surface 12 of the lens 1. The adhesive 22 used here has the same characteristics as those of the first embodiment, that is, it becomes a semi-cured state having elasticity by irradiating the liquid state with ultraviolet rays, and further completely irradiated with the ultraviolet rays. It has the characteristic of becoming a cured state. In FIG. 6A, the adhesive 22 is in a liquid state and can be easily applied to the mounting surface 12.

  As shown in FIG. 6B, in a state where the adhesive material 22 is applied to the mounting surface 12, the adhesive material 22 is irradiated with ultraviolet rays to obtain a semi-cured state having elasticity. Subsequently, as shown in FIG. 6 (c), the lens 1 having the semi-cured adhesive 22 is placed on the optical pickup mounting 5 with the side coated with the adhesive 22 facing down. Use a tool (not shown) to adjust the mounting angle.

  The lens 1 is adjusted to incline in the direction and size for correcting coma aberration measured in advance with respect to the mount 5. At this time, since the adhesive 22 is in a semi-cured state, it can be reliably adjusted in any of the three directions of x, y, and z as in the case of the first embodiment.

  When the mounting angle of the lens 1 is adjusted, as shown in FIG. 6D, ultraviolet rays are irradiated from the surface opposite to the surface to which the adhesive 22 is applied. The ultraviolet rays are transmitted through the flange portion 11 of the lens 1 to make the adhesive 22 in a cured state, and the lens 1 is bonded to the mounting base 5 while maintaining the mounting angle adjusted in FIG.

  As described above, the optical component bonding method according to the present embodiment has substantially the same configuration as the resin molding method provided for the optical component according to the first embodiment. In the first embodiment, the transparent plate is cured after the adhesive is cured. The lens 1 is removed from the optical pickup 23 and placed and fixed on the mounting base 5 of the optical pickup. However, in the present embodiment, the adhesive is cured while being placed on the mounting base 5 and the lens 1 is fixed as it is. Only.

  According to the optical component bonding method of the present embodiment, the adhesive is in a liquid state at the time of application, and the adhesive is in a semi-cured state at the time of adjustment of attachment. By the process of main curing, the mounting position and angle of the optical component can be easily adjusted at the time of mounting, and adjustment after assembly can be made unnecessary.

  Further, in the present embodiment, other components constituting the optical pickup can also be mounted in the optical device according to the present invention. For example, the light emitting unit 2, the light receiving unit 3, and the beam splitter 4 shown in FIG. 1 all require position adjustment with respect to the optical axis, and are fixed at predetermined positions using an adhesive in the optical pickup. . Therefore, an adhesive having the characteristics used in the present embodiment is applied to the bonding position of each component, irradiated with ultraviolet rays in advance to be in a semi-cured state, positioned and adjusted at a predetermined position of the optical pickup, and further irradiated with ultraviolet rays. By irradiating, it can be hardened and fixed by adhesion, whereby position adjustment can be easily performed and adjustment after assembly can be made unnecessary.

  Furthermore, the optical device is not limited to an optical pickup, and the present invention can be applied to other devices. FIG. 7 shows a cross-sectional view of a camera module as an example of an optical apparatus to which the present invention can be applied. As shown in this figure, the camera module includes a holder 30 formed in a cylindrical shape, a lens 32 provided on an inner peripheral surface of a barrel 31 held by the holder 30, and a lens 32 disposed on a substrate 35. A light receiving sensor 33 that converts light to be converted into image data, and a filter 34 disposed between the lens 32 and the light receiving sensor 33 are provided.

That is, in each fixing, a liquid adhesive is applied, and ultraviolet rays are irradiated in advance to leave the adhesive in a semi-cured state, and after adjusting the positioning, further ultraviolet rays are irradiated to cure the adhesive. Perform adhesive fixing.
