In this position, a gap Gp is formed between the upper surface of the second lens 102 and the upper shaft holder 103b ((B) in the figure).

The upper shaft holder 103b is further lowered to move the joint surface of the second lens 102 with respect to the first lens 101 in the arrow Sp direction, and the second lens 102 (optical axis) with respect to the first lens 101 (optical axis Lax1). The first lens 101 and the second lens 102 are joined by performing the optical axis alignment (lens alignment) of Lax2) ((C) in the same figure).

  The lens alignment device 10 irradiates the first lens 1 or the second lens 2 with light used to adjust the position of the first lens 1 (optical axis Lax1) and the second lens 2 (optical axis Lax2). The light from the light source Ls is wavefront converted on the lens surface of the first lens 1 or the second lens 2, and the converted light obtained by the wavefront conversion is incident on the eccentric microscope 6 as observation light Lm. The light source Ls and the eccentric microscope 6 constitute a reference axis Laxb as an adjustment reference position.

Become.

<Embodiment 2>
The method for manufacturing a combination lens according to the present embodiment can be performed using the lens alignment apparatus (see FIG. 1) according to the first embodiment.

  Based on steps S1 to S8 shown below, each process (steps) of a manufacturing method (an assembling method, an optical axis alignment method, a position adjustment method, a lens manufacturing method) of a combination lens that combines the first lens 1 and the second lens 2 ).

Step S1:
The first lens 1 is arranged on the lens holding unit 3 located between the light source Ls and the eccentric microscope 6 to center the first lens. The first lens is centered by aligning the optical axis Lax1 of the first lens 1 with a reference axis Laxb defined by the eccentric microscope 6 and the light source Ls.

  More specifically, the converted light (observation light Lm: see FIG. 1) wavefront-converted on the surface near the light source of the first lens 1 and the converted light (observation light Lm) wavefront-converted on the far surface. The converted light that is observed (detected) by the eccentric microscope 6 serving as converted light detection means and is wavefront converted on the surface near the light source of the first lens 1 and the converted light that is wavefront converted on the surface on the far side are the reference axis Laxb. The first lens 1 is centered by adjusting the arrangement (position) of the first lens 1 so as to coincide with. After centering, the first lens 1 is fixed and held on the lens holding unit 3.

Step S2:
Temporary assembly is performed by fitting and combining the second lens 2 on the opposite side of the light source Ls with respect to the first lens 1.

Step S3:
An eccentric microscope converts the converted light wavefront-converted by the second lens 2 (converted light wavefront-converted on the surface closer to the light source (observation light Lm: see FIG. 1) and converted light wavefront-converted on the far surface). 6 (that is, detected as data by the CCD camera 7 included in the eccentric microscope 6), and the second lens for the first lens 1 (the optical axis Lax1 thereof) by the arithmetic unit 8 based on the data detected by the CCD camera 7. 2 (the optical axis Lax2) is determined as an eccentric state (amount of eccentricity: inclination of the optical axis of the lens (tilt amount α) and amount of center deviation b of the lens (not shown)).

  Specifically, based on the obtained amount of eccentricity, the second lens 2 passes through the intersection of the surface far from the light source and the reference axis Laxb (the optical axis Lax1 of the first lens 1), and is orthogonal to the reference axis Laxb. The intersecting axis Ax2 (see FIG. 2) on the surface far from the light source of the two lenses is calculated.

  FIG. 2 is an explanatory diagram of the method of manufacturing the combination lens according to Embodiment 2 of the present invention, and is perpendicular to the intersecting axis on the surface of the second lens where the tilt amount of the second lens with respect to the first lens is zero. It is a schematic diagram on an adjustment surface including a reference axis (the optical axis of the first lens).

  Since the intersecting axis Ax2 on the surface of the second lens is orthogonal to the reference axis Laxb, the tilt amount (tilt component) of the second lens 2 with respect to the first lens 1 is zero. Therefore, the tilt amount α is the maximum value on the surface of the second lens 2 existing on the plane of the adjustment surface Sax2 perpendicular to the intersecting axis Ax2 and including the reference axis Laxb. That is, the adjustment surface Sax2 is a position where the tilt amount α shows the maximum value.

Step S4:
Tilt with respect to the reference axis Laxb (the optical axis Lax1 of the first lens 1) of the optical axis Lax2 of the second lens 2 using the coordinates of the adjustment surface Sax2 perpendicular to the intersecting axis Ax2 obtained in step S3 and including the reference axis Laxb The amount α (maximum tilt amount α) is calculated.

  Point A is an observation point of converted light wavefront-converted on the surface near the light source of the second lens 2, and point B is an observation point of converted light wavefront-converted on the surface far from the light source of the second lens 2. A straight line connecting A and point B becomes the optical axis Lax2 of the second lens 2. Here, the direction of the reference axis Laxb is the Z axis, and the direction perpendicular to the Z axis on the adjustment surface Sax2 is the X axis. The direction perpendicular to the adjustment surface Sax2 is the Y axis.

The distance ΔX1 and the distance ΔX2 are respective deviation amounts of the point A and the point B with respect to the optical axis Lax1 (reference axis Laxb) of the first lens, and are obtained by the CCD camera 7 as measured values with the eccentric microscope 6.

The tilt amount α of the second lens 2 with respect to the first lens 1 can be obtained by calculation from the shift amount ΔX1 and the shift amount ΔX2.

  A tilt amount (tilt angle) α of the second lens 2 with respect to the first lens 1, a lens center shift amount b (not shown because it is finally erased), a surface of the first lens 1 closer to the light source, and a reference Using the origin O, which is the intersection with the axis Laxb, the distances Z1 and Z2 of the points A and B from the X axis are obtained, and expressions 1 and 2 are established.

ΔX1 = b + Z1 · tan (α) (1)
ΔX2 = b + Z2 · tan (α) (2)
If the center deviation b is deleted from the equations (1) and (2), the equation 3 is obtained.

α = tan ⁻¹ {(ΔX2−ΔX1) / (Z2−Z1)} (3)
That is, the tilt amount α of the second lens 2 is calculated from Equation (3).

  The tilt amount α on the adjustment surface Sax2 represents the maximum tilt amount α as described above.

Step S5:
The first lens 1 is rotated so that the adjustment jig 4 is positioned on the plane of the adjustment surface Sax2 (the adjustment jig 4 is disposed at a position where the tilt amount α is maximum), and then the adjustment jig 4 is used as a reference. The axis Laxb (the optical axis Lax1 of the first lens 1) and the cross axis Ax2 are moved in the X-axis direction by the jig movement distance d (the distance d from the reference axis Laxb to the adjustment position Pc of the adjustment jig 4), and the adjustment position It arrange | positions to Pc (refer FIG. 3).

  FIG. 3 is a conceptual diagram showing an adjustment amount corresponding to the movement state and the tilt amount of the adjustment jig in FIG.

  The adjustment jig 4 must be positioned in the positive direction of the Z axis from the intersection of the reference axis Laxb and the intersecting axis Ax2 (the axis on the surface far from the light source of the second lens orthogonal to the reference axis Laxb). The movement of the adjustment jig 4 (jig movement distance d) is preferably performed up to a portion close to the outer diameter of the second lens 2 in order to increase the adjustment amount h and facilitate adjustment. Although the effective optical surface is preferably moved to a peripheral portion outside the effective optical surface, the present invention is not limited to this and can be set as appropriate.

Step S6:
An adjustment amount h for pressing and adjusting the position of the second lens 2 is calculated from the tilt amount α obtained in step S4 and the appropriately set distance d (jig movement distance d). The adjustment jig 4 is configured to move in a direction parallel to the reference axis Laxb, so that the adjustment amount h can be easily calculated and accurate control can be performed.

  The adjustment amount h can be obtained from Equation 4.

h = d · tan (α) = d · {(ΔX2−ΔX1) / (Z2−Z1)} (4)
)
Step S7:
The position of the second lens 2 is adjusted by the adjustment jig 4 in correspondence with the adjustment amount h calculated by Expression 4.

  Specifically, after calculating the adjustment amount h of the second lens 1, the adjustment jig 4 is moved via the control device 9 by the control signal from the calculation device 8 while rotating the first lens 1 by the turntable 5. Gradually move it in the direction of the arrow Pr, and move the second lens 2 in correspondence with the adjustment amount h. Since the second lens is moved while rotating the first lens 1, the center deviation amount b (see equations 1, 2, and 3) between the lenses is also corrected simultaneously with the correction (adjustment) of the tilt amount α. The optical axis alignment (position adjustment) between the first lens 2 and the second lens 2 is completed.

Step S8:
The first lens 1 and the second lens 2 for which the optical axis alignment has been completed are appropriately bonded and fixed with an adhesive or the like to manufacture a combined lens.

  Note that the calculation (calculation processing) in each step described above can be directly performed using data from the CCD camera 7 in a calculation device 8 constituted by a computer in which a predetermined program is installed in advance.

  Numerical examples in Embodiment 2 are shown (see FIGS. 2 and 3).

  In the combination lens according to Embodiment 2, the first lens 1 is a concave lens and the second lens 2 is a convex lens. When the curvature radius of the combined portion is 5 mm and the outer diameters of both lenses are 7.2 mm, the point A and the point B that are wavefront transformed by the second lens 2 and measured by the eccentric microscope 6 are in the first lens 1. Since the origin O is taken, the Z-axis position of the point A is Z1 = 5.8 mm, and the Z-axis position of the point B is Z2 = 107.1 mm.

When the second lens 2 is fitted into the first lens 1 and the second lens 2 generates a tilt amount α of 20 minutes with respect to the first lens 1, the second lens measured by the eccentric microscope 6. 2 is ΔX1 = 22 μm for the point A and ΔX2 = 60 for the point B.
0 μm.

  In this state, when the manufacturing method according to the second embodiment is applied and the axis of the second lens 2 is aligned with respect to the first lens 1, the adjustment jig 4 is separated from the reference axis Laxb by a distance d = 3. It moves to an adjustment position Pc of 5 mm (about half the outer diameter of the lens). Therefore, since d = 3.5 mm and the tilt amount α = 20 minutes, the adjustment amount h necessary for adjusting the position of the second lens 2 is 17 μm.

By moving (adjusting) the second lens 2 in correspondence with the adjustment amount h = 17 μm, ΔX
A combination lens in which 1 = 1.1 μm, ΔX2 = 25.4 μm, and the tilt amount α between the first lens 1 and the second lens 2 was 0.8 minutes could be obtained. Therefore, the initial tilt amount 20 minutes / the adjusted tilt amount 0.8 minutes = 25, that is, the tilt amount α can be improved (reduced) by 25 times.
