Description
この発明は、携帯電話機や小型モバイル機器に搭載されたカメラなどをはじめとする小型撮像装置に好適な小型の広角単焦点レンズに関する。 The present invention relates to a small wide-angle single-focus lens suitable for a small imaging device such as a camera mounted on a mobile phone or a small mobile device.
近年、携帯電話機やデジタルカメラなどをはじめとする携帯型の撮像装置が広く普及している。そして、近年の撮像装置の小型化にともない、撮像装置に搭載される撮影レンズもより一層の小型化が要求されている。加えて、撮像装置に搭載される撮像素子の高画素化も進んでいるため、これに対応できるように撮像装置に搭載される撮影レンズに対してもさらなる高解像が求められている。そこで、このような要求を満足する小型の撮像レンズが提案されている(たとえば、特許文献1を参照。)。 In recent years, portable imaging devices such as mobile phones and digital cameras have been widely used. With recent downsizing of the imaging device, further downsizing of the photographing lens mounted on the imaging device is required. In addition, since the number of pixels of the image pickup device mounted on the image pickup device is increasing, higher resolution is also required for the photographic lens mounted on the image pickup device so as to cope with this. Thus, a small imaging lens that satisfies such a requirement has been proposed (see, for example, Patent Document 1).
特許文献1に記載の撮影レンズは、レンズ枚数が少ないコンパクトな構成で高解像を達成している。しかしながら、特許文献1に記載の撮影レンズの構成で大口径化を図ろうとすると(特に、Fナンバが2.8以下)、球面収差とコマ収差がともに増大し解像度が著しく低下するという問題がある。 The photographic lens described in Patent Document 1 achieves high resolution with a compact configuration with a small number of lenses. However, when attempting to increase the aperture with the configuration of the photographing lens described in Patent Document 1 (particularly, the F number is 2.8 or less), there is a problem that both spherical aberration and coma aberration increase and the resolution significantly decreases. .
一般に、高解像を実現するためには、レンズ枚数を増やすなどの方法が考えられが、レンズ枚数を増やすと光学系全長も長くなる傾向にある。小型化が要求されている装置への搭載を目的とする以上、光学系全長は厳しく制限されるので、レンズ枚数を増やす場合、レンズのコバや肉厚等を薄くする必要がある。しかしながら、レンズのコバや肉厚等を薄くするのにも限界があり、レンズ枚数を増やし、かつ光学系全長を短縮することは困難である。以上の理由により、特許文献1に記載の撮影レンズでは、小型化を阻害せずに、大口径化と高解像化をともに達成することはできない。 In general, in order to realize high resolution, a method such as increasing the number of lenses can be considered. However, increasing the number of lenses tends to increase the overall length of the optical system. Since the total length of the optical system is severely limited as long as it is intended to be mounted on a device that is required to be miniaturized, when the number of lenses is increased, it is necessary to reduce the edge and thickness of the lens. However, there is a limit to reducing the edge and thickness of the lens, and it is difficult to increase the number of lenses and shorten the total length of the optical system. For the above reasons, the photographic lens described in Patent Document 1 cannot achieve both a large aperture and high resolution without hindering downsizing.
この発明は、上述した従来技術による問題点を解消するため、大口径、高解像でありながらも、小型の広角単焦点レンズを提供することを目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide a small-sized wide-angle single-focus lens that has a large aperture and a high resolution in order to solve the above-described problems caused by the prior art.

この発明によれば、結像性能を劣化させることなく、光学系のより小型化を図ることができる。 According to the present invention, the optical system can be further downsized without deteriorating the imaging performance.
この発明によれば、大口径、高解像でありながらも、小型の広角単焦点レンズを提供することができるという効果を奏する。 According to the present invention, there is an effect that it is possible to provide a small wide-angle single-focus lens while having a large aperture and high resolution.
以下、この発明にかかる広角単焦点レンズの好適な実施の形態を詳細に説明する。 Hereinafter, preferred embodiments of a wide-angle single focus lens according to the present invention will be described in detail.
この発明にかかる広角単焦点レンズは、物体側から順に配置された、正の屈折力を有する第1レンズ群と、負の屈折力を有する第2レンズ群と、正の屈折力を有する第3レンズ群と、負の屈折力を有する第4レンズ群と、正の屈折力を有する第5レンズ群と、負の屈折力を有する第6レンズ群と、備えて構成される。このように、正の屈折力を有する第1レンズ群、負の屈折力を有する第2レンズ群、および正の屈折力を有する第3レンズ群を備えて構成したことにより、球面収差の補正が良好になる。 The wide-angle single focus lens according to the present invention includes a first lens group having a positive refractive power, a second lens group having a negative refractive power, and a third lens having a positive refractive power, which are arranged in order from the object side. The lens group includes a fourth lens group having a negative refractive power, a fifth lens group having a positive refractive power, and a sixth lens group having a negative refractive power. As described above, since the first lens group having the positive refractive power, the second lens group having the negative refractive power, and the third lens group having the positive refractive power are provided, the spherical aberration can be corrected. Become good.
さらに、この広角単焦点レンズでは、前記第3レンズ群の近傍、好ましくは前記第2レンズ群と前記第3レンズ群との間で前記第3レンズ群に近い位置に所定の口径を規定する開口絞りを配置する。そして、前記第2レンズ群を物体側に凸面を向けた負のメニスカスレンズで、前記第4レンズ群を像側に凸面を向けた負のメニスカスレンズで構成している。これにより、光学系のレンズ構成を前記開口絞りに対してコンセントリックにすることができ、非点収差とコマ収差を抑制して広角化を図ることが可能になる。 Further, in this wide-angle single focus lens, an aperture that defines a predetermined aperture in the vicinity of the third lens group, preferably between the second lens group and the third lens group, at a position close to the third lens group. Arrange the aperture. The second lens group is a negative meniscus lens having a convex surface facing the object side, and the fourth lens group is a negative meniscus lens having a convex surface facing the image side. As a result, the lens configuration of the optical system can be made concentric with respect to the aperture stop, and astigmatism and coma aberration can be suppressed to achieve a wide angle.
さらに、この広角単焦点レンズでは、前記第6レンズ群を近軸では負の屈折力を有し周辺にいくにしたがって正の屈折力が強くなるレンズにより構成している。これにより、像面に入射する主光線をテレセントリックに近づけることが可能になり、像面に配置される撮像素子における光線の受光効率の低下を抑制することができる。 Further, in this wide angle single focus lens, the sixth lens group is constituted by a lens having a negative refractive power on the paraxial axis and a positive refractive power increasing toward the periphery. As a result, it becomes possible to make the principal ray incident on the image plane closer to telecentricity, and it is possible to suppress a decrease in the light receiving efficiency of the image sensor arranged on the image plane.
この発明にかかる広角単焦点レンズでは、前記第1レンズ群ないし前記第3レンズ群で前群を構成し、前記第4レンズ群ないし前記第6レンズ群で後群を構成する。そして、前記前群を光軸に沿って像面側から物体側へ移動させることにより、無限遠合焦状態から最至近距離合焦状態までのフォーカシングを行う。このようにすることにより、レンズ群内の芯ズレによる光軸ズレを抑制することができる。また、この広角単焦点レンズとともに用いるレンズ駆動機構の簡略化を図ることができ、レンズ駆動機構の製造コストの低減化を図ることができる。なお、至近距離撮影時には、前記第3レンズ群を光軸に沿って像側から物体側へ移動させることにより、フォーカシングを行うことが可能である。また、至近距離撮影時には、前記第4レンズ群を光軸に沿って物体側から像側へ移動させることによっても、フォーカシングを行うことができる。前記第3レンズ群および前記第4レンズ群はそれぞれ1枚のレンズで構成することができるため、光学系の小型軽量化とレンズ駆動機構の簡略化を図ることが可能になる。 In the wide-angle single focal length lens according to the present invention, the first lens group to the third lens group constitute a front group, and the fourth lens group to the sixth lens group constitute a rear group. Then, the front group is moved from the image plane side to the object side along the optical axis to perform focusing from the infinite focus state to the closest focus state. By doing in this way, the optical axis shift by the core shift in a lens group can be suppressed. Further, it is possible to simplify the lens driving mechanism used with this wide-angle single focus lens, and to reduce the manufacturing cost of the lens driving mechanism. During close-up shooting, focusing can be performed by moving the third lens group from the image side to the object side along the optical axis. In close-up shooting, focusing can also be performed by moving the fourth lens group from the object side to the image side along the optical axis. Since each of the third lens group and the fourth lens group can be composed of a single lens, it is possible to reduce the size and weight of the optical system and simplify the lens driving mechanism.
この発明にかかる広角単焦点レンズは、以上のような特徴を備えているので、大口径化を図っても高い光学性能を維持することができる。また、6群であっても各群はそれぞれ1枚のレンズで構成することができるため、光学系の小型化を図ることができる。したがって、大口径、高解像でありながらも、小型の広角単焦点レンズを提供することができる。 Since the wide-angle single focus lens according to the present invention has the features as described above, high optical performance can be maintained even when the aperture is increased. Further, even if there are six groups, each group can be composed of a single lens, so that the optical system can be miniaturized. Therefore, it is possible to provide a small wide-angle single-focus lens while having a large aperture and high resolution.
また、この発明にかかる広角単焦点レンズでは、前記第1レンズ群を、物体側から順に配置された、正レンズと、負レンズとにより構成し、前記正レンズと前記負レンズとを接合してもよい。このようにすることで、公差を緩めることができる。 In the wide-angle single focal length lens according to the present invention, the first lens group includes a positive lens and a negative lens arranged in order from the object side, and the positive lens and the negative lens are joined. Also good. By doing so, the tolerance can be relaxed.
また、この発明にかかる広角単焦点レンズでは、前記第5レンズ群を、物体側から順に配置された、負レンズと、正レンズとにより構成し、前記負レンズと前記正レンズとを接合してもよい。このように構成しても、公差を緩めることができる。 In the wide-angle single focus lens according to the present invention, the fifth lens group includes a negative lens and a positive lens arranged in order from the object side, and the negative lens and the positive lens are cemented together. Also good. Even with this configuration, the tolerance can be relaxed.
また、この発明にかかる広角単焦点レンズでは、前記前群の焦点距離をFFG、前記後群の焦点距離をFRGとするとき、次の条件式を満足することが好ましい。
(1) −0.8<FFG/FRG<−0.1
In the wide-angle single focal length lens according to the present invention, it is preferable that the following conditional expression is satisfied when the focal length of the front group is F FG and the focal length of the rear group is F RG .
(1) −0.8 <F FG / F RG <−0.1
条件式(1)は光学系全系のバックフォーカスの長さを規定するための式である。この条件式(1)で規定された範囲を満足することで、結像性能を低下させることなく、光学系全長の短縮化を図ることが可能になる。条件式(1)においてその下限を下回ると適切なバックフォーカスをとることができなくなり、結像性能の低下を招く。一方、条件式(1)においてその上限を超えるとバックフォーカスが長くなりすぎ、光学系全長が延び、光学系の小型化が阻害される。 Conditional expression (1) is an expression for defining the length of the back focus of the entire optical system. By satisfying the range defined by the conditional expression (1), it is possible to shorten the overall length of the optical system without deteriorating the imaging performance. If the lower limit of conditional expression (1) is not reached, an appropriate back focus cannot be obtained, resulting in a decrease in imaging performance. On the other hand, if the upper limit in conditional expression (1) is exceeded, the back focus becomes too long, the entire length of the optical system is extended, and downsizing of the optical system is hindered.
なお、上記条件式(1)は、次に示す範囲を満足すると、より好ましい効果が期待できる。
(1)’ −0.6<FFG/FRG<−0.2
この条件式(1)’で規定する範囲を満足することにより、より光学系の小型化を達成しつつ、結像性能の向上を図ることができる。
In addition, the said conditional expression (1) can anticipate a more preferable effect, if the range shown next is satisfied.
(1) '−0.6 <F FG / F RG <−0.2
By satisfying the range defined by the conditional expression (1) ′, it is possible to improve the imaging performance while further reducing the size of the optical system.
以上説明したように、この発明にかかる広角単焦点レンズは、上記のような特徴を備えているので、大口径、高解像でありながらも、小型の広角単焦点レンズになる。そして、上記条件式を満足することにより、結像性能を劣化させることなく、光学系のより小型化を図ることができる。 As described above, since the wide-angle single focus lens according to the present invention has the above-described features, it becomes a small wide-angle single-focus lens while having a large aperture and high resolution. By satisfying the above conditional expression, the optical system can be further downsized without deteriorating the imaging performance.

また、図20は、実施例7にかかる広角単焦点レンズの無限遠合焦状態における諸収差図である。図21は、実施例7にかかる広角単焦点レンズの最至近距離合焦状態における諸収差図である。図中、dはd線(λ=588nm)、gはg線(λ=436nm)、FはF線(λ=486nm)、CはC線(λ=656nm)、eはe線(λ=546nm)に相当する波長の収差を表す。そして、像面湾曲図における符号S,Mは、それぞれサジタル像面、メリディオナル像面に対する収差を表す。 FIG. 20 is a diagram illustrating various aberrations of the wide-angle single focus lens according to Example 7 in an infinitely focused state. FIG. 21 is a diagram of various aberrations of the wide-angle single focus lens according to Example 7 in the closest focus state. In the figure, d is d line (λ = 588 nm), g is g line (λ = 436 nm), F is F line (λ = 486 nm), C is C line (λ = 656 nm), e is e line (λ = 546 nm). Symbols S and M in the field curvature diagram represent aberrations with respect to the sagittal image surface and the meridional image surface, respectively.
なお、上記数値データにおいて、r1,r2,・・・・は各レンズなどの曲率半径、d1,d2,・・・・は各レンズなどの肉厚またはそれらの面間隔、nd1,nd2,・・・・は各レンズなどに対するd線の屈折率、νd1,νd2,・・・・は各レンズなどに対するd線のアッベ数を示している。 In the above numerical data, r 1, r 2, · · · · is the radius of curvature, such as the lens, d 1, d 2, · · · · is the thickness or their spacing of such individual lenses, nd 1 , Nd 2 ,... Indicate the d-line refractive index for each lens, and νd 1 , νd 2 ,.
また、上記各非球面形状は、光軸方向にX軸、光軸からの高さをYとし、光の進行方向を正とするとき、以下に示す式により表される。 Each of the aspherical shapes is expressed by the following expression when the X axis is in the optical axis direction, the height from the optical axis is Y, and the light traveling direction is positive.
ただし、Rは近軸曲率半径、εは円錐係数、A,B,C,D,E,F,G,Hはそれぞれ2次,4次,6次,8次,10次,12次,14次,16次の非球面係数である。 Where R is the paraxial radius of curvature, ε is the conic coefficient, A, B, C, D, E, F, G, and H are the second, fourth, sixth, eighth, tenth, twelfth, and 14th, respectively. Next, 16th-order aspheric coefficients.
以上説明したように、上記各実施例の広角単焦点レンズは、前群を、正の屈折力を有する第1レンズ群、負の屈折力を有する第2レンズ群、および正の屈折力を有する第3レンズ群を備えて構成したことにより、球面収差の補正が良好になる。さらに、前記第3レンズ群の近傍に所定の口径を規定する開口絞りを配置し、前記第2レンズ群を物体側に凸面を向けた負のメニスカスレンズで、前記第4レンズ群を像側に凸面を向けた負のメニスカスレンズで構成している。これにより、光学系のレンズ構成を前記開口絞りに対してコンセントリックにすることができ、非点収差とコマ収差を抑制して広角化を図ることが可能になる。さらに、前記第6レンズ群を近軸では負の屈折力を有し周辺にいくにしたがって正の屈折力が強くなるレンズにより構成している。これにより、像面に入射する主光線をテレセントリックに近づけることが可能になり、像面に配置される撮像素子における光線の受光効率の低下を抑制することができる。 As described above, the wide-angle single focus lenses of the above-described embodiments have the front group, the first lens group having a positive refractive power, the second lens group having a negative refractive power, and the positive refractive power. By including the third lens group, the spherical aberration can be corrected well. Further, an aperture stop defining a predetermined aperture is disposed in the vicinity of the third lens group, the second lens group is a negative meniscus lens having a convex surface facing the object side, and the fourth lens group is positioned on the image side. It consists of a negative meniscus lens with a convex surface. As a result, the lens configuration of the optical system can be made concentric with respect to the aperture stop, and astigmatism and coma aberration can be suppressed to achieve a wide angle. Further, the sixth lens group is constituted by a lens having a negative refractive power on the paraxial axis and a positive refractive power increasing toward the periphery. As a result, it becomes possible to make the principal ray incident on the image plane closer to telecentricity, and it is possible to suppress a decrease in the light receiving efficiency of the image sensor arranged on the image plane.
上記各実施例の広角単焦点レンズは、以上のような特徴を備えているので、大口径化を図っても高い光学性能を維持することができる。さらに、上記条件式を満足することで、結像性能を劣化させることなく、光学系のより小型化を図ることができる。また、上記各実施例の広角単焦点レンズは、少ないレンズで構成できることも、光学系の小型化が可能な要因の一つである。したがって、大口径、高解像でありながらも、小型の広角単焦点レンズを提供することができる。さらに、上記各実施例の広角単焦点レンズは、適宜非球面が形成されたレンズや接合レンズを用いているため、少ないレンズ枚数で、良好な光学性能を維持することができる。 Since the wide-angle single focus lens of each of the above embodiments has the characteristics as described above, high optical performance can be maintained even when the aperture is increased. Furthermore, by satisfying the above conditional expression, the optical system can be further downsized without deteriorating the imaging performance. Further, the fact that the wide-angle single focus lens of each of the above embodiments can be configured with a small number of lenses is one of the factors that can reduce the size of the optical system. Therefore, it is possible to provide a small wide-angle single-focus lens while having a large aperture and high resolution. Furthermore, since the wide-angle single focus lens of each of the above embodiments uses a lens or a cemented lens in which an aspheric surface is appropriately formed, good optical performance can be maintained with a small number of lenses.
以上のように、この発明にかかる広角単焦点レンズは、撮像素子が搭載された小型携帯型撮像装置に有用であり、特に、大口径、高解像が要求される装置に最適である。 As described above, the wide-angle single-focus lens according to the present invention is useful for a small portable imaging device equipped with an imaging device, and is particularly suitable for a device that requires a large aperture and high resolution.
