Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stereomicroscope having a pair of observation optical axes having inward angles that coincide with each other at a sample position.
[0002]
[Prior art]
The stereomicroscope has a pair of independent observation optical systems in both the left and right eyes, and enables the sample to be viewed stereoscopically by observing the sample from different directions. Stereomicroscopes can be divided into an internal oblique type (Greeneau type) and a parallel type (Galileo type) according to the arrangement of the optical axes of the left and right objective lenses.
[0003]
In the inner oblique type, the optical axes of the left and right objective lenses are arranged at an angle with respect to the sample. In the parallel type, the optical axes of the objective lenses are arranged in parallel.
[0004]
These types of stereomicroscopes irradiate a sample with illumination light emitted from an epi-illumination device, and cause reflected light from the sample, that is, observation light, to enter an objective lens. The incident observation light is imaged by the objective lens and obtained as an observation image through the eyepiece.
[0005]
In such a stereomicroscope, an image pickup device such as a photographic camera or a television camera (TV camera) is attached to take an image of a sample. In order to capture an observation image of a sample, an optical path switching device as disclosed in Patent Document 1, for example, is used for a stereomicroscope.
[0006]
This Patent Document 1 describes that a reflecting member is detachably provided on one observation optical axis of a pair of observation optical axes of a stereomicroscope, and the observation light from the sample is branched to the imaging device side. .

[Problems to be solved by the invention]
When an imaging device is attached to a stereomicroscope and an observation image of a sample is taken, if external light other than the observation light from the sample enters the observation optical system, flare or ghost may occur in the observation image taken by the imaging device. is there.
[0009]
For example, when the observer takes an image at a position away from the eyepiece lens, external light from a fluorescent lamp or the like enters one observation optical system through the eyepiece. The invading external light is irradiated onto the sample surface through the objective lens of one observation optical system. Then, the reflected light from the sample enters the objective lens of the other observation optical system, and enters the imaging device via the reflecting member of the optical path switching device. As a result, flare and ghost are generated. As a method for preventing the occurrence of such flare and ghost, there is a method for preventing intrusion of external light by covering the eyepiece with a cap.
[0010]
However, in this method, it is necessary to attach the cap to the eyepiece every time an observation image is taken, which is troublesome. There is also a risk of losing the cap.
[0011]
As another method for preventing the occurrence of flare and ghost, there is a method of disposing a polarizing plate on the observation optical system. In this method, since the polarizing plate is disposed on the observation optical path even when observing a normal sample, the observation image becomes dark. In addition, the use of a polarizing plate causes a cost increase.
[0012]
Accordingly, an object of the present invention is to provide an inexpensive stereomicroscope that can easily perform good imaging without generating flare and ghost when an observation image is captured.

Accordingly, when the first support member 90 is inserted into the side wall 7a of the stereomicroscope main body 7 by operating the knob 36a, the first reflecting member 41 is moved to the observation optical axis L. ₁ Placed on top. At this time, the knob 36a comes into contact with the side wall 7a, so that the knob 36a serves as a stopper and the first reflecting member 41 is moved to the observation optical axis L. ₁ Positioned above.

At this time, when one knob 36a abuts against the side wall 7a, the knob 36a serves as a stopper, and the first reflecting member 41 is moved to the observation optical axis L. ₁ Position the light shield plate 44 on the observation optical axis L ₂ Position up.

By this contact, the first support member 90 is prevented from sliding leftward in the drawing by the action of the knob 36a as a stopper. Further, when the knob 36b is pulled out, the coupling by the magnetic force with the tip of the first support member 90 by the magnet 92 is cut off, and the first support member 90 and the second support member 91 are slid independently. It becomes possible to move.
[0074]

In this state, the observer can observe the sample 2 through the eyepiece lens 32.
[0077]
As described above, according to the seventh embodiment, it is needless to say that the same effects as those of the first embodiment can be obtained, and the connected first and second support members 90 and 91 are operated once. By the operation, the first reflecting member 41 and the light shielding plate 44 are slid integrally to each observation optical axis L. ₁ , L ₂ Can be inserted and removed.
[0078]
