Description

Stereoscopic microscope image transmission device for biological microscope {Dual image device for physicalmicroscope and biomicroscope}

The present invention relates to a stereomicroscope image transmission device for both biological microscopes that combines stereomicroscope functions and biological microscope functions into one system to transmit microscope images to a projector and large monitor.

There are two types of microscopes used in schools for educational purposes: biological microscopes, which observe tissue cells and viruses, and stereomicroscopes, which observe the shape and surface of real objects.

Biological microscopes mainly observe cellular tissue through which light transmits, so the tissue is composed of a thin film on a preparat that mainly transmits light, and is observed at a magnification of 200 to 2000 times. The magnification is high, the aperture of the objective lens is small, and the focal length is small. is short and light must be transmitted from behind the observation object.

A stereo microscope illuminates the surface of an object through which light cannot pass through and observes with reflected light, and is mainly observed at a magnification of 5 to 100 times. Therefore, the objective lens must have a large aperture, a short focal length, and illuminate the surface of the object. do.

It is not a configuration that selects and observes images of .

In this way, biological microscopes and stereo microscopes differ in the structure and function of the optical system, the configuration position of the illumination system, and the focal ratio distance, so each was equipped separately for the number of students.

Therefore, in the past, the biological microscopes and physical microscopes were required separately for each student, resulting in a large economic burden, and the educational effect was reduced because the microscope images observed by students and those seen by teachers were different from each other.

In consideration of the above problems, the present invention combines the biological microscope function and the stereo microscope function in one system, allowing multiple students and teachers to simultaneously observe the biological microscope image and the stereo microscope image on a large screen or monitor at any time. Suggests a way to do this.

The present invention includes left and right vertical supports provided vertically at appropriate intervals on both the left and right sides of one pedestal, left and right vertical supports provided on the left and right vertical supports, and these left and right vertical supports. It consists of left and right platforms that are connected to each other and move in the left and right up and down directions.

The upper part of the left stage is equipped with a first objective lens for a stereo microscope.

At the top of the right stage, a number of second objective lenses for biological microscopes with different magnifications are combined, and it consists of a rotating plate that selects the objective lens according to rotation.

In the present invention, as shown in FIGS. 1 and 2, the main body 100 is provided with one pedestal 1, and a first optical system 200 and a second optical system 300 are formed on the left and right surfaces of the pedestal 1. .

The first optical system 200 and the second optical system 300 are composed of an optical coupling device 400 that combines into one optical system through one optical path (A), and is incident on the camera device 14. This will be explained in detail based on the drawings.

In this invention, as shown in Figures 1 and 2, a stand (1) is formed at the lower part of the main body (100), and the stand (1) is provided with a left vertical support (2) and a right vertical support (3) at predetermined intervals in the left and right directions. ) is provided in the vertical direction.

The left vertical support (2) moves from the lower part to the left moving stand (4) and the left loading stand (7) in the left moving stand (4) in the up and down directions by the left handle (5).

The upper part of the left stage (7) is equipped with a first objective lens (6) for a stereo microscope to achieve a total magnification of between 5 and 100 times, and on the upper part of the left stage is a left refractive reflector ( 8), the first optical system 200 is provided.

The right vertical support (3) is connected to the right vertical support (4a) and the right stage (7a) from the bottom, and the right stage (7a) moves in the up and down directions by the right handle (5a).

The upper part of the right stage (7a) is equipped with a second objective lens (6a) for biological microscope use to achieve a total magnification of between 100 and 2000 times, and this second objective lens (6a) is attached to the rotating plate (6b) structure. Objective lenses of various magnifications are provided so that the total magnification can be varied, and the second optical system 300 is provided on the top of the second objective lens 6a by forming a right refractive reflector 8a that reflects at a right angle to the left. do.

It is known that the magnification of the objective lens is determined by the ratio of the length of the second focal distance to the first focal distance by the self-focal distance of the objective lens and the magnification of the eyepiece, so the longer the barrel length, the higher the magnification.

In order to connect the first optical system 200 and the second optical system 300 as described above in one structure, an optical coupling device 400 is formed between the left refractive reflector 8 and the right refractive reflector 8a. In order to block external light in the left and right directions of the optical coupling device 400, it is connected to the left refractive reflector 8 and the right refractive reflector 8a through a horizontal barrel 9.

The double-sided reflector 11 is composed of a double-sided reflector 11 in which both the front and back surfaces are reflective surfaces.

When the double-sided reflector 11 is configured as a reflector structure, both the front and back sides must be composed of reflective surfaces, such as the front reflector 11c and the rear reflector 11d, as shown in Figure 3 (a).

A rotation axis (11a) is provided at the center of this double-sided reflector (11), and the rotation axis (11a) is connected to the conversion handle (11b) and rotates at a right angle of 90° in the up and down directions by the conversion handle (11b). .

By the same logic, as shown in Figure 3 (b), the structure of the double-sided reflector 11 is composed of two right-angled prisms and combining the oblique surfaces of each prism to form a single rotating body, with a rotating axis ( 11a) and a conversion handle 11b is provided on the rotation axis 11a.

A camera device 14 is configured on the top or bottom of the optical coupling device 400.

If necessary, the double-sided reflector 11 is configured as a reflector or prism whose left and right reflecting surfaces reflect at right angles, as shown in Figure 3 (c), and the image incident from both the left and right is divided and sent to the camera device 14. It can be configured to join at the same time.

Between the left refractive reflector 8 and the right refractive reflector 8a and the optical coupling device 400 or the optical coupling device 400 and the camera device 14, there is an auxiliary device for adjusting the optical path length, viewing angle, or magnification. The lens 10 can be additionally configured for each necessary element.

Additionally, if necessary, a polarizer can be additionally installed in front of the lighting device and between the first and second objective lenses 6 and 6a and the camera device 14.

Therefore, in the present invention, in the first optical system 200, an actual object to be observed, that is, an opaque object that does not transmit light, such as a rock, tissue, the surface of a metal, or a living insect, is placed on the first objective lens 6 and the surface illumination device 13 ), then the left stage (7) is moved up and down by the left handle (5) to focus the first objective lens (6).

The image of the actual observation object magnified by the first objective lens 6 is incident on the left refractive reflector 8 and then refracted and reflected in the horizontal left direction to the double-sided reflector 11 of the optical coupling device 400. It enters the front reflector 11c.

In the second optical system 300, a transparent observation object prepared with biological tissues, cells, etc. is placed on the right stage 7a, the back side of the transparent object is illuminated by the back illumination device 12, and the rotating plate 6b is used. Select one of several second objective lenses (6a) provided according to the required magnification and focus by moving the right stage (7a) up and down with the right handle (5a).

The enlarged image of a transparent object such as tissue of a living organism is incident on the right refractive reflector 8a and is then refracted and reflected in the horizontal right direction to enter the rear reflector 11d of the double-sided reflector 11.

In order to combine the stereoscopic microscope function, which is a heterogeneous opaque object observation function, and the biological microscope function, which is a transparent object observation function such as Preparat, into one microscope function, the present invention includes the left refractive reflector 8 of the first optical system 200 and the second optical system 200 as shown in FIG. 2. 2. The right refractive reflector 8a of the optical system 300, the rotation axis 11a of the double-sided reflector 11, and the center of the camera device 14 must be formed by one optical path A.

If this structure is not configured, it becomes impossible to combine two heterogeneous optical systems into one camera device 14 in one structure.

Therefore, the horizontal height of the central optical path A of the left refractive reflector 8 and the right refractive reflector 8a is fixed to the same height.

The rotation axis 11a and the central axis of the camera device 14 are also fixed to the same optical path A.

This double-sided reflector 11 rotates in the up and down directions by the rotation axis 11a, as shown in Figure 3 (a) and Figure 3 (b).

This rotation can be rotated within a fixed angle, such as within 90 degrees, as needed.

Therefore, the image of the first optical system 200 and the image of the second optical system 300 incident on the double-sided reflector 11 from both left and right are rotated by the double-sided reflector 11 according to the rotation of the conversion handle 11b. Therefore, the stereomicroscope image coming from the left and the biological microscope image coming from the right are selected and entered into the camera device 14.

The image incident from the camera device 14 can be observed simultaneously by a number of students and teachers on a screen (not shown) linked to the large monitor 15 or the projector 16, as shown in FIG. 5.

As another example of the present invention, as shown in Figure 3 (c), the double-sided reflector 11 is configured with a left refractive reflector 8 and a right refractive reflector 8a in a parallel orthogonal reflection structure to provide a stereomicroscope. The observation image and the biological microscope observation image are divided into one optical path (A) and enter the camera device (14) at the same time, so that the two images can be viewed simultaneously on a screen through one monitor (15) or projector (16). .

As another example of embodiment, as shown in FIG. 4, instead of the left refractive reflector 8, the left camera device 14a is coupled to the upper part of the first objective lens 6, and the right refractive reflector device is installed on the upper part of the second objective lens 6a. Instead of (8a), combine the right camera device (14b)

In this case, the focal length of the first objective lens 6 can be adjusted by moving the first objective lens 6 and the left camera device 14a up and down.

The image of the left camera device 14a and the image of the right camera device 14b are input separately, and the two images are provided in the image combining device 400a, which is composed of one system.

In this system, the stereomicroscope image observed through the first objective lens 6 of the left camera device 14a is input to the left image input terminal of the image combining device 400a, is connected to the left image switch 17a, and is connected to the second objective. The biological microscope image observed through the lens 6a is input to the input terminal of the image combining device 400a by the right camera device 14b and connected to the right image switch 17b.

The left image switch 17a and the right image switch 17b are connected to a monitor 15 or a projector 16 combined with a screen through one output terminal 18, depending on selection.

That is, the stereomicroscope image of the first optical system 200 and the biological microscope image of the second optical system are displayed on the monitor 15 or the large screen according to the selection of the left and right image switches 17a and 17b configured in one image combining device 400a. Stereoscopic microscope images or biological microscope images are selected and displayed in real time on a projector (16) combined with a screen.

For example, when observing the same petal, the first optical system 200 implements an image of the actual appearance of the pistil and stamen of the opaque petal, and the second optical system 300 prepares the tissue such as the pores of the transparent petal. After implementing the image, the actual nature of the petal and the tissue of the petal can be alternately observed simultaneously by rotating the conversion handle (11b).

Therefore, the first optical system 200 with a stereo microscope function and the second optical system 300 with a biological microscope function, which are coupled to the left and right vertical supports 2 and 3 on one pedestal 1, are integrated into one main body 100. By combining them, the teacher and multiple students can select and observe stereomicroscope images or biological microscope images from one microscope body by rotating the conversion handle (11b) and the left and right image switches (17a, 17b).

For example, in the past, the shape and form of petals were viewed with a stereomicroscope, and the tissue shape, such as the pores of the petal tissue, was observed separately with a biological microscope structure, but the present invention uses a conversion handle (11b) to convert the surface shape structure and biological cell tissue structure of the observed object. ) or by selecting the left and right image switches (17a, 17b), immediate observation is possible alternately.

Therefore, the present invention combines images from two optical systems constructed in one main body 100 in the left and right directions with the optical coupling device 400 or the image combining device 400a to display them on one monitor 15 or one image combining device 400a. Since it can be selected and implemented on the screen using the projector (16), it can be effectively used in schools, research institutes, semiconductor production sites, hospitals, etc.
