With the configuration having four free-form surfaces, very good aberration performance can be realized. Since the single lens Ln other than the central single lens L13 has a decentered optical axis AX in order to form a peripheral visual field, it is not necessary to use an optical path changing prism or the like. Therefore, all the monocular lenses Ln can have the same thickness and can be designed on the same substrate.

- the examples given here are numerical examples corresponding to the above-described embodiments, and an optical configuration diagram (FIG. 5) showing an embodiment of the compound-eye optical system LH is a lens configuration, an optical path, and the like of the corresponding numerical examples. Is shown.
- Table 1 shows the area arrangement of the single lens Ln in the example and the comparative example.
- the single lens Ln is arranged at 5 ⁇ 5 positions, and the entire optical system L0 is arranged at 3 positions.

- r (mm), shaft upper surface distance d (mm), and Y eccentricity (mm) are shown.
- the “90 degree rotation” of the single lens Ln means that a state in which a surface is created according to the construction data and rotated 90 degrees around the Z axis is the lens state. Therefore, the eccentric direction and the free-form surface coefficient are the same as when X and Y are interchanged (the H direction corresponds to the X direction and the V direction corresponds to the Y direction).
- the central single lens Ln (position: C) that is rotationally symmetric about the optical axis AX uses an aspherical surface that is rotationally symmetric about the optical axis AX. It is defined by the following equation (AS) using an orthogonal coordinate system (X, Y, Z). A free-form surface is used for the peripheral single-lens Ln (position: V1, VD, D1, V2, D2, HD, H2, H1), which is a decentered optical system, and the free-form surface has its surface vertex.

- FIG. 7B is a schematic diagram showing the imaging range of the example
- FIG. 7C is an arrangement of the compound eye optical system.
- FIG. Table 4 is a table showing the photographing range and optical system data of each individual lens in the example
- Table 5 is a table showing the photographing range and optical system data of each individual lens in the comparative example.
- the following shooting range VD, D2, H2, D1, HD, and H1 satisfy the following expression (1), and the surrounding shooting range D1 satisfies the following expression (2).
- FIGS. 8A, 8B, 8C, and 8D are graphs showing the MTF values in the imaging ranges D1, V1, H1, and C of the comparative example.
- FIGS. (D) is a graph showing MTF values in the imaging ranges D1, V1, H1, and C of the example. 8A to 8D and FIGS. 9A to 9D are apparently compared with each other, the MTF peak value and the image plane property in the peripheral imaging range are particularly larger than those in the comparative example. The example improved and the effect of the present invention was confirmed.
- the imaging range of the imaging area is reduced by narrowing the imaging range of the peripheral single lens with respect to the imaging range of the central single lens. Since the amount can be reduced, the amount of eccentricity of the lens surface (or the lens group) can be reduced. As a result, it is possible to obtain a single-lens lens having a good imaging performance with little focus shift, and a compound eye optical system having a good imaging performance can be configured.
- the value of the expression (3) or (4) is equal to or greater than the lower limit value, the photographing range of the central single-lens lens is not excessively wide. It is possible to provide a compound eye optical system with good optical performance that is not large.
- three or more individual lenses are arranged in the horizontal direction and the vertical direction. With this configuration, since the photographing range of each single-lens lens can be reduced, the amount of field curvature at the boundary of the photographing range can be reduced, and a compound-eye optical system having good imaging performance can be obtained. .
- the single lens includes at least two lenses, and the peripheral single lens has a free curved surface on at least one surface. Thereby, it can be set as the compound eye optical system which is favorable image formation performance.
- magnification of the single lens is substantially the same. This eliminates the need to align the magnifications of the images when processing the images formed through the individual lenses, thereby simplifying the stitching process of the images and providing a low-cost imaging device. .
- a light-shielding stop between the single-lens lens and the image plane.
- the light-shielding stop it is possible to adopt a configuration that prevents light from entering other than the imaging surface corresponding to each individual eye (to prevent crosstalk), so that a compound eye optical system with good imaging performance is obtained. I can do it.
