Description of the Related Art A conventional binocular stereomicroscope, as shown in FIG. 5, includes an illumination optical system including a light source 1, a collector lens 2, a diffusion plate 3 and a condenser lens 4, a stage 5 for holding a sample S, and an objective. The lens 6 and the zoom lenses 7a and 7b and the eyepieces 8a and 8b are arranged to be symmetrical, and a pair of observation optical systems are arranged. The optical axes 9a and 9b of the pair of observation optical systems are respectively inclined by an angle α / 2 with respect to the optical axis 10 of the illumination optical system. That is, the optical axes 9a and 9b are symmetrically positioned with the extension line of the optical axis 10 as the axis of symmetry.

下し、観察光学系の視野が全体的に暗くなってしまう。However, since the diffusing plate 3 of the illumination optical system has the directivity as shown in FIG. 6, as shown in FIG. Illumination unevenness occurs in which the outside of each field of view becomes dark. This is because the directivity of the diffusing plate exhibits a strong directivity in the optical axis direction of the illumination optical system, and the light intensity is significantly reduced as the deflection angle of the diffusing light beam is not large. In order to solve this uneven illumination, it is good to use a diffuser with a high diffusivity, that is, a diffuser with a small directivity. The field of view of the system becomes dark as a whole.

ことである。Further, it is disclosed in Japanese Patent Laid-Open No. 60-111201 that a pair of lenses is used instead of a diffusion plate to divide the observation optical system into two directions along the optical axis. However, if a pair of lenses is used, only a part of the light flux from the condenser lens can be split in two directions, and the illumination efficiency will be reduced. In view of such a problem, an object of the present invention is to provide a transillumination device for a binocular stereomicroscope having no illumination unevenness and good illumination efficiency.

系で実体観察する。Next, the operation of this binocular stereomicroscope will be described. The illumination light flux from the light source 1 is condensed by the collector lens 2 and becomes a substantially parallel light flux. The light beam splitting prism 13 is
The substantially parallel light flux from the collector lens 2 is split, and is deflected to a light flux in a direction substantially along the optical axes 9a and 9b of the pair of observation optical systems. The light beam thus divided and deflected illuminates the sample S from the direction along the optical axes of the pair of observation optical systems via the condenser lens 4. In this way, the image of the sample illuminated by the transillumination device is stereoscopically observed by the pair of observation optical systems provided on the respective optical axes 9a and 9b.

る。The split deflection in the light beam splitting prism 13 is a plane (paper surface) including the optical axes 9a and 9b of the observation optical system.
And is deflected in a plane parallel to the plane of the drawing, and in the vertical plane including the optical axis 9a and orthogonal to the plane of the paper, or in the vertical plane including the optical axis 9b and orthogonal to the plane of the paper, division or There is no bias. Therefore, the conventional transillumination device using the diffusion plate 3 diffuses in all directions, and the transillumination device using a pair of lenses divides and deflects only part of the light beam from the condenser lens. While the illumination efficiency is poor, the transmissive illumination device of the embodiment using the light beam splitting prism 13 allows almost all of the light beams from the condenser lens 2 to be in a direction substantially parallel to the optical axes 9a and 9b. Since it is deflected, the illumination efficiency is extremely good, and since the deflected illumination light flux becomes the illumination light flux substantially along the optical axes 9a and 9b, there is no illumination unevenness. Further, in consideration of the overall configuration of the binocular stereomicroscope, the diffuser plate 3 can be manufactured at a low cost because it has a simple configuration in which only the light beam splitting prism 13 is changed.

る。In the above-mentioned embodiment, the beam splitting prism consisting of a plurality of chevron rows is used, but each chevron row may be formed in a V-shaped row, and the surface of the prism has at least a pair of slopes. It is only necessary to form one, but if a pair of slopes is used, the illumination area on the sample becomes narrow. In addition, the inclination angle of each inclined surface of the light beam splitting prism 13 is determined by considering the opening angle α between the optical axes 9a and 9b and the refractive index of the material so that the deviation angle θ of the prism 13 becomes θ = α / 2.

As shown in FIG. 4, the magnification of the objective lens 6 is changed by adding an auxiliary lens 6 ′ to the objective lens 6. However, in this case, since the distance between the sample S and the objective lens 6 changes with the observation magnification,
The opening angle α between the optical axes 9a and 9b changes before and after exchanging the observation magnification. Therefore, the optical axes 9a and 9b before the magnification change
The illumination light flux along the line is displaced from the direction of the optical axis after the magnification is changed, and uneven illumination occurs. If the opening angle α between the optical axes 9a and 9b changes by exchanging the observation magnification in this way, the light beam splitting prism 13 is moved to the optical axis 9a after the magnification is changed.
And 9b are replaced with prisms 13 'having a deflection angle .theta. =. Alpha.' / 2 according to the opening angle .alpha. ', And the illumination light fluxes are changed in the respective optical axis directions after the magnification is changed. Specifically, the light beam splitting prisms 13 and 13 'are connected by a slider (not shown), and the slider is replaced by sliding it in the direction of the arrow. For this exchange, a plurality of prisms may be housed in a turret-shaped metal object and the turret may be rotated. Further, as a matter of course, when the observation magnification is changed by removing the objective lens 6 and exchanging it with another objective lens having a different magnification, similarly, the prism is changed according to the opening angle α ′ after the magnification is changed.

Therefore, compared with the conventional transillumination device using the diffusion plate, since it does not diffuse in a wasteful direction, the illumination efficiency is good,
Moreover, it is possible to perform illumination without uneven illumination.
