も不足している。The image guides used for these are extremely thin with an outer diameter of a few tenths of a millimeter, so the conventional method of attaching an adapter to a fiberscope with an eyepiece reduces the apparent field of view when observing with the eyepiece. It is small and extremely difficult to observe, making it complicated to handle. Furthermore, the optical system from the image guide to the solid-state imaging device has a small zoom ratio and is insufficient in total magnification.

Next, when we compare the changes in the ray height between the first to second lens groups and the fourth lens group when the variator of the third lens group moves during zooming, we find that the amount of change in the fourth lens group is large. be. This fourth
In order to suppress aberration fluctuations due to changes in the height of the rays that occur in the lens group, it is desirable to make the fourth lens group ■ nearly symmetrical, so that the image point of the third lens group III, that is, the object of the fourth lens group TV. It is preferable to form a shape close to abranatic with respect to the point and the image point of the fourth lens group. For this purpose, it is desirable to set β4 to a value near -l.
以上のことがらβl2を一定値以上にすることによって
光学系を高倍率にする必要がある。そのために設けたの
が条件(1)である。したがってこの条件(11 を満
足しない高倍率化を実現し得なくなる。For the above reasons, it is necessary to increase the magnification of the optical system by setting βl2 to a certain value or more. Condition (1) was established for this purpose. Therefore, it becomes impossible to achieve high magnification that does not satisfy this condition (11).

って前記条件(3)を満足ずる必要がある。Similarly, condition (3) is also provided for compactness. FIG. 32 shows the relationship between the magnification β3 of the third lens group III and the distance between the object and image of this lens group. When the zoom ratio is Z, IO is the minimum and the amount of lens movement is small because of the magnification β of the third lens group III.
3 centered on -1, β3W = - l/r d. β3,
=-ff (β2 W +β3 lenses are each at the wide end.The magnification of the third lens group at the telephoto end). Therefore, it is necessary to satisfy the above condition (3).
又第3レンズ群(バリエーター)の移動量Δは次のよう
に示すことが出来る。Further, the movement amount Δ of the third lens group (variator) can be expressed as follows.
Δ= f3(1/β3W−l/β3T)このΔの値を小
にして第3レンズ群IT[の移動を小さくするためにも
必要な条件である。Δ=f3(1/β3W-l/β3T) This is also a necessary condition for reducing the value of Δ and reducing the movement of the third lens group IT[.
条件(41.+51は、光学系のバックフォーカスを規
定したものである。Condition (41.+51 defines the back focus of the optical system.
光学系のバックフォーカスS゜は、次の式で与えられる
。The back focus S° of the optical system is given by the following equation.
S’ =f4+1−β4)
もしf4が条件(4)の下限値の8を越えるか、β4が
条件(5)の上限値の−0.5を越えると第4レンズ群

が短くなる。S' = f4 + 1 - β4) If f4 exceeds the lower limit of 8 in condition (4) or β4 exceeds -0.5, the upper limit of condition (5), the power of the fourth lens group ■ becomes large. As a result, the upper vertical coma aberration is large and under-corrected when the lens is wide. Also, the lower limit of condition (4). Condition (5)
If it is within the upper limit of , install a crystal filter in front of the solid-state image sensor. Infrared power filters, YAG cut filters, etc. can be appropriately arranged, and if the range is exceeded, the back focus will not be long. Further, if the upper limit of condition (4) of 40 or the lower limit of condition (5) of -5 is exceeded, the back focus becomes short.
更に次の条件+61 . (7)を満足することが好ま

?件(6)は、物体側の最大物体高からの主光線の傾き

ちないようにするために設けたものである。゛この条件
を満足しないと、周辺光量が十分確保出来ない。? Condition (6) is provided in order to limit the inclination angle of the chief ray from the maximum object height on the object side to prevent the peripheral light amount of the image guide from dropping more than necessary. ``If this condition is not satisfied, a sufficient amount of peripheral light cannot be secured.
条件(7)は像側の最大像高へ入射する主光線の傾き角

iこ対する色シェーデインクの問題を生ずる。Condition (7) limits the inclination angle of the principal ray that enters the maximum image height on the image side. If this condition is not met, CCD
This causes problems with color shading ink.
更に前記の条件(6)は、入射瞳が■ほぼ無限遠である

レンズ群の前後では光線高が変動するので、この第3レ
ンズ群の前後に絞りを配置することも適当でない。した
がって明るさ絞りは、第1レンズ群と第2レンズ群の間
に配置するのが最も適している。Furthermore, condition (6) above means that the entrance pupil is almost infinite, and condition (7) means that the exit pupil is almost infinite, considering the path of the chief ray. In this case, the aperture stop cannot be placed in front of the first lens group or after the fourth lens group. Furthermore, since the third lens group is a variator, the height of the light ray changes before and after this lens group, so it is not appropriate to arrange an aperture before and after this third lens group. Therefore, it is most suitable for the aperture stop to be placed between the first lens group and the second lens group.
更に前述のように倍率β12を高くするために第11
1レンズ群はかなりパワーが強くなり、収差が発生しや
すい。又第2レンズ群がコンペンセー夕、第3レンズ群

2レンズ群〜第4レンズ群とで各々独立に収差補正を施
すのが全系の収差を補正する上で適切である。そのため
にち明るさ絞りは第1レンズ群と第2レンズ群の間に配
置すべきである。Furthermore, as mentioned above, in order to increase the magnification β12, the power of the 111st lens group becomes considerably strong, and aberrations are likely to occur. Also, considering that the second lens group is a compensator and the third lens group is a variator, the aberrations of the entire system can be corrected independently by the first lens and the second to fourth lens groups. It is appropriate for correcting. Therefore, the aperture stop should be placed between the first lens group and the second lens group.
次に、第lレンズ群のフォーカシングのための移動や第
2レンズ群のコンペンセーターとしての移動により生ず
る収差変動がないようにするためには次の条件(8)を
満足することが望ましい。Next, in order to prevent aberration fluctuations caused by movement of the first lens group for focusing and movement of the second lens group as a compensator, it is desirable to satisfy the following condition (8).
(8)1 θl<10’
ただしθは光軸に対するマージナル光線の傾き角である
。(8) 1 θl<10' where θ is the inclination angle of the marginal ray with respect to the optical axis.
この条件(8)を満足しないと、第1レンズ群,第2レ
ンズ群の上記の移動による両レンズ群間隔の変化によっ
て収差が移動するので好ましくない。If this condition (8) is not satisfied, it is not preferable because aberrations will shift due to the change in the distance between the first and second lens groups due to the above-mentioned movement of the first lens group and the second lens group.

と第2レンズ群の間を脱着可能にしてもよい。Furthermore, l2? as an aberration correction means in a zoom lens. Separate achromatism is used by arranging at least six cemented lenses in a lens group. In addition, from the viewpoint of bint movement, the NA from the image guide is large because β12 is increased as described above, and the distance to the first surface of the first lens group has a variation within 0.01 accuracy in practice. You won't be able to focus if you don't make sure that it's not there. For this reason, rather than combining the 1st lens group and the 2nd lens group into a moving group, the distance between the 1st lens group and the end surface of the image guide is always kept constant even when the image guide is moved 1#JJ. (The image guide end face is placed near the front focal point of the first lens group.) The mechanical structure is such that the light beams are almost parallel to the second lens group, and a convencator or variator is installed after the second lens group. If you place
Spacing fluctuations caused by variations in the cam rings can be sufficiently absorbed between the first lens group and the second lens group, where the light rays are substantially parallel, and no focus shift occurs. Furthermore, the first lens group and the second lens group may be made detachable.
又イメージガイドと第1レンズ群とは、設計上脱着して
も一定位置関係が保たれているが、更にその位置を基準
位置として位置関係を調整可能にしてフォーカシング機
構としてもよい。Furthermore, although the image guide and the first lens group are designed to maintain a fixed positional relationship even when they are attached and detached, the positional relationship may be adjusted using that position as a reference position to form a focusing mechanism.
