Abstract

Provided are a combined lens and an imaging device capable of effectively minimizing unwanted light which leads to ghost and flare, while reducing the cost. The flange of a lens has a transitional surface outside the effective diameter. When the transitional surface extends in a direction orthogonal to the optical axis, unwanted light can be suppressed and costs reduced by the formation of a black membrane (BKM). When transitional surfaces are mutually separated or inclined to a direction orthogonal to the optical axis, a shielding plate (AP) can be provided to increase the suppression effect for the unwanted light.

Description

Compound lens and filming apparatus
Technical field
The present invention relates to compound lens and filming apparatus, wherein, compound lens is applicable to the filming apparatus with the solid-state image pickup element such as CCD type image sensor or CMOS type image sensor.
Background technology
In recent years, the mobile terminal being equipped with the filming apparatus employing the solid-state image pickup element such as CCD type image sensor, CMOS type image sensor is day by day universal.In the filming apparatus being equipped on such mobile terminal, in order to obtain the image of more high image quality, the device employing the capturing element of high pixel count is put into the market.Although the capturing element physique with high pixel count is comparatively large, in recent years, along with height fine and closely wovenization of pixel, capturing element has been miniaturized gradually.Be accompanied by this, be equipped on the lens unit of filming apparatus, except being required low back, be also required to guarantee that high-precision assembling improves productivity.
Here, using lens unit as the compound lens be made up of multiple lens time, do not have helpful unnecessary light (without using up) that ghost image, dazzle can be caused to imaging, in order to suppress without using up, carry out making the process of shading piece clamp between each lens (with reference to patent documentation 1).And, in recent years, propose replacement anti-dazzling screen, and apply the technology (with reference to patent documentation 2) of light-proofness coating.Due to by coating light-proofness coating, without the need to anti-dazzling screen, thus parts number of packages obtain reduction and assembleability also improve, this contributes to the mass production of lens unit, and then contributes to cost degradation.
Patent documentation 1: Japanese Unexamined Patent Publication 2009-282264 publication
Patent documentation 2: Japanese Unexamined Patent Publication 2011-100056 publication
But, can confirm and there is new problem in conventional art as described above.First, in order to meet the high pixelation of lens, low back and mass production, the number of lens adds, and in order to meet the assembleability (can omit adjustment procedure technology) needed for mass production, the flange part outside the effective diameter of lens becomes the shape implementing various design.But the known countermeasure in order to ghost image, dazzle, even if want to be realized without the suppression of using up by the coating of light-proofness coating, the shape of flange part also can become obstacle, there is this and alleviates such problem without the inhibition of using up.
Summary of the invention
The present invention in view of the above problems, its object is to provide a kind of can reduce cost and can effectively suppress to cause ghost image, dazzle without the compound lens used up and filming apparatus.
The feature of the first compound lens of the present invention is, in the compound lens of lens combining more than 3 coaxially, each lens have flange part in effective diameter outside, the face, image side of the above-mentioned flange part of one of them lens is directly or indirectly abutted with the object side of the above-mentioned flange part of other lenses, and above-mentioned flange part is inside the optical axis orthogonal directions of the face, above-mentioned image side mutually abutted and above-mentioned object side and be have transition face in the outside of effective diameter, when at least one party of opposed above-mentioned transition face is orthogonal with the optical axis, at a square one-tenth photomask of above-mentioned transition face, when the both sides of opposed above-mentioned transition face are relative to inclined light shaft, shadow shield is configured between above-mentioned transition face.
The present inventor they through further investigation, found that and only formed photomask at the flange part of lens this can't to suppress fully without using up.In addition, they have found that it can be subject to the impact of the complicated shape of flange part.First, as the method that the man-hour realizing manufacturing process reduces, the effective diameter outside also existed to the optical surface of adjoined lens extends, and the face, image side of the flange part to optical axis direction displacement is abutted mutually with object side, thus the axle base of lens can be adjusted accurately, and eccentric technology can be suppressed.In such a configuration, if arrange photomask between the face, image side mutually abutted and object side, then also exist because of this thickness deviation and the possibility of the deviation of the axle base of lens increase.
On the other hand, inside the optical axis orthogonal directions of face, image side and object side, and be that photomask is set at the transition face in the outside being formed at effective diameter, thus the axle base of lens can be guaranteed accurately, while suppress without using up.But the known difference according to transition face shape, even if form photomask also there is situation about can not block without using up.In other words, because transition face is formed at the face between the optical surface of lens and the face, image side of flange part or object side, so depend on the shape of optical surface, the shape of transition face can change.Here, such as, in the transition face approximating situation opposed in the mode extended to optical axis orthogonal directions, photomask is set at the transition face of a side and can effectively catches without using up.But, when with a pair these both sides of transition face at the mode of optical axis side opening mutual relative tilt, exist have passed in effective diameter without using up the incident and possibility be allowed through in the transition face side never arranging photomask.
Therefore, in the present invention, due to when at least one party of opposed above-mentioned transition face is orthogonal with the optical axis, photomask is set thus effectively plays function, so suppress, without using up, to realize cost degradation thus at a square one-tenth photomask of above-mentioned transition face.On the other hand, due to when the both sides of opposed above-mentioned transition face are relative to inclined light shaft, even if arrange photomask can not play effective function, so configure shadow shield by replacing between above-mentioned transition face, improve the inhibition without using up.In addition, manage the thickness of shadow shield accurately, thus the axle base of lens can be guaranteed accurately.In addition, so-called " formation black film " refer to by ink-jet apply black ink, stamp black ink, coating black film, paste black belt, etc.
The feature of the second compound lens of the present invention is, in the compound lens of lens combining more than 3 coaxially, each lens have flange part in effective diameter outside, the face, image side of the above-mentioned flange part of one of them lens is directly or indirectly abutted with the object side of the above-mentioned flange part of other lenses, and above-mentioned flange part is inside the optical axis orthogonal directions of the face, above-mentioned image side mutually abutted and above-mentioned object side and be have transition face in the outside of effective diameter, when the optical axis direction ultimate range of opposed above-mentioned transition face is equal to or greater than the axle base between lens, shadow shield is configured between above-mentioned transition face, when the optical axis direction ultimate range of opposed above-mentioned transition face is less than the axle base between lens, at a square one-tenth photomask of above-mentioned transition face.
In the same manner as the first compound lens, in the present invention, due to when the optical axis direction ultimate range of opposed above-mentioned transition face is less than the axle base between lens, photomask is set thus effectively plays function, so suppress, without using up, to thus achieve cost degradation at a square one-tenth photomask of above-mentioned transition face.On the other hand, due to when the optical axis direction ultimate range of opposed above-mentioned transition face is equal to or greater than the axle base between lens, even if arrange photomask can not play effective function, so configure shadow shield by replacing between above-mentioned transition face, improve the inhibition without using up.
The feature of filming apparatus of the present invention is, has above-mentioned first compound lens or the second compound lens and solid-state image pickup element.
