It was difficult to create a compact configuration. Furthermore, since the optical path is not perpendicular, it is difficult to adjust the optical axis, which increases the difficulty in manufacturing and processing the lens barrel.

Since the ridgeline where the two slopes intersect is not necessary, the cross-sectional shape is cut out as shown in the perspective view of FIG. 2, so that the cross-section is formed as a prism with an isosceles trapezoid.

４光路へと導かれる。The light beam traveling along the second optical path formed perpendicularly to the objective lens optical axis 1a by the prism 4 as the second reflecting member is reflected by the third reflecting member after intersecting the optical axis of the objective lens. It is reflected by the mirror 6, and the optical axis 1a of the objective lens
It is reflected along a third optical path parallel to and guided to the object O side. The light flux from this third optical path is reflected by a movable mirror 7 as a fourth reflecting member and guided to a fourth optical path having an eyepiece 8 at a downward viewing angle θ.
そして、上記の第１から第４までの各反射部材は、全て

れる構成となっている。The first to fourth reflecting members described above are all located on a plane (the plane of the drawing) that includes the optical axis 1a of the objective lens 1, and the light flux from the object is reflected along this plane. The configuration is as follows.

点位置近傍に物体の二次像１２として形成される。In such an optical path configuration, the imaging lens 3 is disposed in the first optical path between the beam splitter 2 as the first reflecting member and the prism 4 as the second reflecting member, and the imaging lens 3 is arranged in the first optical path between the beam splitter 2 as the first reflecting member and the prism 4 as the second reflecting member. forming an intermediate image I, near or within it; Then, the prism 4 as the second reflecting member and the third
A negative lens 5a disposed on both sides of the optical axis 1a of the objective lens 1 is disposed in the second optical path between the reflection mirror 6 as a reflection member.
A relay lens 5 having a positive lens 5b and a positive lens 5b is disposed, whereby an intermediate lens 5 is formed as a secondary image 12 of an object near the front focal position of the eyepiece 8.

にて観察することができる。Therefore, the intermediate image X1 formed by the objective lens 1 and the imaging lens 3 is an inverted image, but the secondary image I, which is re-imaged by the relay lens 5, is an erect image. and,
Since there is an even number of reflections, 6 times in total, from the first reflecting member to the fourth reflecting member, there is no inversion of the image due to reflection, and the direction of the secondary image 2 is determined by the lens system. The image becomes erect, and the object can be observed in an upright position through the eyepiece.

察者の観察姿勢に応じて適宜変えることも可能となる。Here, in order to change the viewing angle observed through the eyepiece 8, that is, the inclination angle θ of the fourth optical path having the eyepiece, as shown by the broken line in FIG. is configured such that its inclination angle can be changed by a means (not shown) around an axis perpendicular to the plane (plane of the paper) containing the optical axis la of the objective lens as the center of rotation.At this time, the amount of change in the inclination angle of the reflecting mirror 7 is Needless to say, this is -half of the required change in the viewing angle θ.Furthermore, the reflecting mirror 6 as the third reflecting member is also configured so that its inclination angle can be changed, so that the angle of inclination of the reflecting mirror 6 is changeable. If the direction of the parallel third optical path can be changed, the viewing angle can be changed by combining it with the reflector 7 as the fourth reflector, and the direction from the reflector 6 as the third reflector to the eyepiece can be changed. By arbitrarily changing the distance up to 8, it is also possible to change the position of the eyepiece relative to the object to be examined as appropriate depending on the observation posture of the observer.

。In the above configuration, the imaging song 3 forms an object image as an intermediate image II which is smaller than the direct image I formed by the objective lens 1, and this reduced image is enlarged by a predetermined magnification by the relay lens 5. Secondary image I2 of desired size
For example, it is desirable to form an intermediate image (■) by the imaging lens 3 by 2 minutes (7) 1 mm, and then magnify it by a factor of 2 by the relay lens, so that the result is equal to the direct image (■) by the objective lens. It can be a secondary image of size 2. Further, as shown in the figure, by configuring the relay lens 5 with a negative lens 5a and a positive lens 5b disposed on both sides of the optical axis 1a of the objective lens 1, the principal point of the relay lens can be substantially converted into a third reflection. By locating it near the member 6, it is possible to increase the degree of freedom in the arrangement of each member. Moreover, the presence of the negative lens 5a allows the Petzval sum as a relay lens to be corrected even better, and it is possible to maintain the flatness of the image plane well.

ある。In the above embodiment, a substantially isosceles triangular prism 4 is used as the second reflecting member having three reflecting surfaces, but the prism 4 is not limited to this, and for example, a so-called pentaprism 40a and a reflecting prism 40b are used. It is also possible to configure the second reflecting member with the above. In this case, Ventab 1
Even if the prism 40a is disposed at an angle in a plane (plane of paper) perpendicular to its both incident planes, the adjustment can be made easy due to the advantage that it does not affect the light rays exiting this prism. However, there is also the drawback that the second reflective member is composed of two elements. In the prism 4 as the second reflecting member in the embodiment shown in FIG.
Since the two reflective surfaces are integrally constructed, there is an advantage that the number of parts is reduced, and therefore the number of supporting members thereof is also reduced.

It is configured to be detachable. In a state in which the variable viewing angle lens barrel is attached, it is possible to project an object image I formed by a beam of light passing through the beam splinter 2 serving as the first reflecting member using a television or a still camera.

である。As described above, according to the present invention, all the optical paths except the final optical path where the eyepiece is arranged are composed of optical paths that intersect at right angles, so that it is easy to adjust the configuration of the optical system, especially the centering adjustment, and to adjust the alignment of the lens barrel. The structure and processing become simple. Furthermore, the six reflections required to observe an erect image can be contained within a small space, making it possible to downsize the entire configuration of the viewing angle variable viewing optical system. In addition, unlike in the past (because the optical paths do not intersect diagonally, there are fewer restrictions on the placement of the relay lens and each reflective member, and therefore there is a high degree of freedom in design and it is possible to improve the performance of the optical system. Furthermore, since it is possible to increase the vector radius of each optical element, it is advantageous for constructing an ultra-wide-field observation optical system.
