Abstract

PURPOSE: To simplify and miniaturize a microscope, by utilizing a small transparent sphere whose magnification becomes larger in inverse proportion to its diameter. CONSTITUTION: A sheet 1 is provided with a hole 2, and the diameter of the hole 2 is smaller than that of the transparent sphere 3 to be inserted therein. The sphere 3 is protected by two transparent sheets 4 composing planes in common with both sides of the sheet 1. Then, an object 5 to be observed is directly put on out outside surface of the transparent sheets 4, and observation is performed by seeing through from the other side of transparent sheet 4 toward an outside light point 6 across the hole 2. Therefore, the object 5 is located with an exact focal distance defined by the thickness of the sheets 1 and 4 corresponding to the diameter of the sphere 3 adopted to this assembly, hence largely magnified, and made possible to clearly observe. As a result, the number of components can be reduced and the constitution can be simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a simple microscope, and more particularly to a simple microscope that has superior performance characteristics when compared with other known complex instruments with the same object and magnification.

(Prior Art) As is well known, in order to obtain a clear image, a conventional microscope is comprised of a strong support base, a slide focusing means, and an illumination means in addition to a magnifying lens support mechanism. For this reason, it is not only expensive, but also requires special handling methods, is cumbersome to carry, and its use is limited to research institutes and educational centers where students rarely have the opportunity to use it. .

Other disadvantages of the above conventional microscopes are that they are heavy and cumbersome to carry, which prevents them from being used for certain types of observation, especially at specific sites or at just the right moment.

(Problems to be Solved) Unlike the above-mentioned drawbacks, the present invention is highly simplified and miniaturized, and can be easily carried for research, etc.
The aim is to popularize this type of observation means and to provide a simple microscope that can be used most economically for educational purposes.

(Structure of the Invention) The principle feature of the present invention is to utilize the magnification of a small transparent sphere, which can obtain a very large magnification as its diameter is made smaller.

The small stocks are placed in corresponding cavities within a narrow rectangular support sheet and protected through transparent sheets adhered to both sides of the support sheet.

In order to obtain the desired magnification with a sphere having a predetermined diameter, the focal length is made constant and dependent on the curvature. The object to be observed is placed in contact with one of the two transparent protective sheets, and the sheet has an appropriate thickness to achieve a predetermined focal length.In this way, the number of component parts of the microscope is reduced and the number of components is reduced. The configuration is considered simple.

In a further improved embodiment without complication, a laminated slide is combined with the above-mentioned sphere support, on which the object to be observed is placed, in contact with or in close proximity to the sphere-protecting transparent sheet. However, this short distance is limited by the thickness of the glass covering the object.

For example, if an observation is made by looking through a light bulb or similar illumination device or sphere aimed at natural light, the object will be magnified with a high magnification and a very sharp image will be obtained because it is placed at the correct focal length. can get.

Looking at the numerical symbols shown in the drawings, it can be seen that the simple microscope of the present invention has been reduced to a preferably rectangular narrow sheet, as indicated by the numeral 1. A hole 2 is provided, which hole 2 has a smaller diameter than the transparent bulb 3 inserted therein.The bulb 3 is protected by two transparent sheets 4 coplanar with both sides of the sheet 1 and is shown in FIG. It is fixed in a position with no gaps as shown in the figure.

The object 5 to be observed is placed directly on the outer surface of one of the transparent sheets 4, and is observed by looking through the hole 2 from the other transparent sheet 4 toward the external light spot 6.

Since the object 5 is placed with a precise focal distance defined by the thickness of the sheets 1 and 4 relative to the diameter of the sphere 3 used in the assembly, it can be observed with surprising magnification and sharpness.

If desired, natural spherical aberration can be avoided by using only the center of the sphere; otherwise,
In most observations, the natural spherical aberration is not a problem.

Although not shown, if a slide is used as the sheet 1, the object will be better protected during observation, and especially if the microscope is used for educational purposes, the object will be placed in the correct position corresponding to the sphere 3. It must be placed with the focal length. This is achieved by appropriately determining the thickness of the transparent sheet 4 and the thickness of one of the slides. This configuration is not shown in the drawings.

It is possible to use the same sheet 1 as a support for a plurality of transparent spheres with different diameters. In order to aggregate different magnifications in the same device, balls are placed for each corresponding person regularly distributed on the device.

The ball or balls may together with the support form a single element. In addition, the support can emit light and/or
Alternatively, other additional elements that facilitate light collection may be included.
