ある。これらのズームレンズは、口径比がF/2.8以
上で、ズーム比も3倍以上のものがほとんどである。[Prior Art 1] Zoom lenses are most commonly used as lenses for photographic devices that use electronic image pickup tubes or solid-state image sensors as photographic devices. Most of these zoom lenses have an aperture ratio of F/2.8 or more and a zoom ratio of 3 times or more.
このように従来のこの種のズームレンズは、口径比が大

少ない部類のズームレンズである。The zoom lens disclosed in Japanese Patent Application Laid-Open No. 60-123817 is
Its basic configuration consists of, in order from the object side, a first group that has positive refractive power and is fixed when changing magnification and is movable only when focusing, and a first group that has negative refractive power and is movable for changing magnification. The second group has a positive refractive power and moves in a convex trajectory toward the image side to correct the image plane that changes due to zooming, and the third group has an imaging function and is always fixed. In this way, in this conventional example, the first group has three lenses, the second group has three lenses,
The zoom lens has a total of 11 lenses, one in the third group and four in the fourth group, and is one of the zoom lenses with the smallest number of lenses among the recently known conventional examples.

No attempt has been made to reduce C, and these 1st to 3rd groups are used in zoom 1 lenses with a large number of lenses, such as JP-A-60-184220 and JP-A-51-
It has the same number of lenses as the zoom lens described in No. 99037.

である。1 Measures for solving the problem 19.1 In order to achieve the above object, the zoom lens of the present invention has a first lens group having a positive refractive power and a negative refractive power in order from the object side. The groove is formed by the 21st !T having a positive refractive power, the third group having a positive refractive power, and the fourth group having a positive refractive power.
During zooming, the first group and the front two [l and 4n are fixed, and the first group consists of three lenses in order from the object side: a negative lens with a convex surface facing the object side, a positive lens, and a positive lens. In the zoom 1 lens, the 2nd n is made up of two lenses in order from the object side: a negative meniscus single lens with a strongly concave surface facing the image side, and a negative lens with a concave surface on the object side.

In the present invention, in order to reduce the number of constituent lenses, the second group, which is composed of two negative lenses and a positive lens in a conventional zoom lens, is divided into two, which is the combined magnification of the third group. A new method has been adopted in which the image position is kept constant by dividing the lens into two parts and changing the distance between the two parts slightly when the second group is moved for magnification. This allows the variator to
With a small number of lenses (three including the lens and compensator), fluctuations in chromatic aberration due to zooming can be extremely minimized (while fluctuations in the image plane position can also be corrected and the zoom ratio can be increased).

能になる。Furthermore, since the distance between the second group and the third group of the zoom lens of the present invention changes to become the largest at intermediate focal lengths, the distance at the top of the space can also be minimized at the telephoto end where the distance is desired to be reduced. I can do it. At the same time, the focal length can be set to the telephoto end, close to Ji, such that the distance between the 3nth lens and the 4th lens group, which is a fixed group behind it, is a minimum value of 1. This makes it possible to minimize the waste of movable space in the variable magnification system, which allows the entrance pupil (usually the diaphragm is placed just in front of the fixed group) to be shallower when viewed from the first surface. It is possible to reduce the diameter of the ball and photograph objects at closer distances.

のがよい。Furthermore, in order to obtain a zoom lens with stable zooming performance, the first group consists of a negative meniscus lens with a convex surface facing the object side, a positive lens, and a positive lens in order from the object side, and the second group consists of a negative meniscus lens whose convex surface faces the object side. It is best to construct the lens with two lenses, a negative meniscus-shaped single lens with a strongly concave surface facing the image side, and a negative lens with a concave surface facing the object, and the third group with a positive single lens. .

率側にシフトさせる必要がある。そのために条件(1)
を満足させる必要がある。In the conventional example, the second group is made up of three lenses in order to prevent chromatic aberrations etc. from shifting during zooming. When the third lens group is moved while changing the distance between them, chromatic aberration etc. tend to fluctuate and become misaligned.In other words, if the movements of the two lens groups mentioned above are significantly different, various aberrations including chromatic aberration will be disrupted when changing the magnification. In addition, when trying to move the third group to compensate for the movement of the image plane when moving the second group on the optical axis to change the magnification, the third group moves relative to the second group. In order to prevent the interval from becoming too thick, it is necessary to shift the range of change in the image magnification of the second group to a much lower magnification side than that of the conventional example.For this purpose, condition (1) is satisfied.

ースの有効利用上好ましくない。The upper limit of the condition +11 (if it exceeds 0.71, the amount of change in the mutual distance between the second and third groups will be large and the fluctuation of chromatic aberration during zooming will increase, which is undesirable); The mobile units in the third group become larger than the group, making it difficult to reduce the distance between the second and third groups at the telephoto end, which is not preferable in terms of effective use of space.

なりやすい。The 4th group tends to be long and large, and if you try to make it smaller forcibly, various aberrations such as spherical aberration and coma aberration tend to worsen, and if the upper limit (3,0) is exceeded, the focal length of the 4th group will be shortened. As a lens for an electronic imaging device, the pack focus is short (it tends to be short), and if you try to make it too long, the power of each lens element in the 4th group, especially the negative lens, will become too strong, resulting in coma flare, etc. Further, if either the upper or lower limit of condition (2) is exceeded, the variation in the relative distance between the second group and the third group tends to become large.

層望ましい。In this way, even if the variable power system of a 4-group zoom lens (the lens group that controls the variable power function and image position correction function) consists of only 3 elements in total, it will still be as good as or better than a conventional 4-group zoom lens. In order to obtain good compactness, variable magnification ratio, F-number, and a good degree of aberration correction, the power arrangement of the variable magnification system and how to determine the Abbe number are important factors. Therefore, it is more desirable to satisfy the following conditions (3) to (6).

The distance fI is the focal length of the third group, and fI is the Abbe number of the second lens on the object side (k=1.2).

(なる。Condition (3) defines the combined focal length of the second group and the third group. The variable power ratio in the present invention is substantially the second
Determined by the combined power of the group and the third group. If the upper limit of this condition exceeds 1.21, the zoom ratio will not increase, or the total length of the lens system will become long, or the diameter of the front group will become large.If the lower limit value of this condition exceeds 0.51, the total length will increase. This is advantageous in shortening the lens and reducing the diameter of the front lens, but the stability of aberrations (spherical aberration, coma aberration, astigmatism) during zooming is poor.

マ収差、非点収差が変動しやすくなる。Condition (4) defines the ratio of the focal length of the third group and the combined focal length of the second and third groups. This is specified because the third group positive lens needs to have a certain amount of power in order to prevent fluctuations in chromatic aberration during zooming and to correct fluctuations in image position. If the upper limit of this condition exceeds 6.01, it becomes difficult to suppress fluctuations in chromatic aberration and image position during zooming.
If O, a) is exceeded, the combined power of the second and third groups, which are variable magnification groups, will weaken, making it difficult to satisfy condition (3), or the power of the second group will become too strong, resulting in a spherical surface when changing magnification. Aberration, coma aberration, and astigmatism become more likely to fluctuate.

変動しそして変倍領域全体にわたって倍率の色収差が補
正不足になる。Condition (5) defines the difference between the average value of the Atsube numbers of the second group and the Atsube numbers of the third group. This is to reduce fluctuations in chromatic aberration during zooming, and it is desirable that this difference be as large as possible for actually existing glass materials. When the lower limit value (15) of the condition is exceeded, the chromatic aberration during zooming changes, and the chromatic aberration of magnification becomes insufficiently corrected over the entire zooming region.
条件(6)は、第1群から第3群までの広角端での合成
焦点距離を規定したものである。従来例は、いわゆるエ
レクタ−(第4群)を射出する光束がほぼアフォーカル
光束であっていわゆるリレー系である固定群にほぼアフ
ォーカルで入射する。Condition (6) defines the composite focal length of the first to third groups at the wide-angle end. In the conventional example, the light beam emitted from the so-called erector (fourth group) is substantially afocal and enters the fixed group, which is the so-called relay system, almost afocal.

し、いわゆるバックフォーカスの長いレンズ系を得るこ
とも要求される。この点からも本発明のズームレンズの
ような構成は好ましい。However, when a configuration like the zoom lens of the present invention is adopted, the so-called variable magnification system light beams emitted from the first group to the third group become weak diverging light beams, and enter the 4th F3 fixed group as a diverging light beam. become. The purpose of use of the present invention is the same as that of JP-A-60-184220, which was invented by the inventor of the present invention, and it is also required to obtain a lens system with a so-called long back focus. Also from this point of view, a configuration like the zoom lens of the present invention is preferable.
このように固定群に発散光束が入射すると、固定群自身
のバックフォーカスを長くしなくともレンズ系のバック
フォーカスを長く出来、固定群を変則的なパワー配分に
して収差を悪化させたり構成枚数を増加させたすせずに
バックフォーカスを長く保つことが出来る。When a diverging beam of light enters the fixed group in this way, the back focus of the lens system can be lengthened without increasing the back focus of the fixed group itself, and the power distribution of the fixed group becomes irregular, worsening aberrations and reducing the number of constituent elements. It is possible to maintain the back focus for a long time without increasing the focus.
条件(6)の上限値(−0,2)を越えると変倍系から

絞り゛の入る空気間隔の公差が厳しくなりやすくなる。If the upper limit (-0, 2) of condition (6) is exceeded, the luminous flux from the variable magnification system will have no divergence, making it difficult to maintain a long back focus. If this is too strong, the diameter of the l-non in the fixed group tends to become large, and the tolerance of the air gap where the diaphragm enters tends to become strict.
