{A focus variable type lense and mirror for education}

TECHNICAL FIELD The present invention relates to lenses and mirrors, and more particularly to a variable lens and a mirror so that the curvature can be converted into various mirrors and lenses with one device.

Generally, concave and convex lenses are made or molded by processing transparent synthetic resin such as transparent glass or acrylic. The concave mirror or convex mirror is made by processing transparent synthetic resin such as glass or acrylic and coating silver or aluminum.

Concave lens, convex lens, convex mirror, concave mirror made as described above are used a lot in our real life, but will be used in the state of being made individually, especially in the educational field.

And. In the educational field, as shown in Figure 1 is also used to make a variable lens (VR), the variable lens (VR) is made of a transparent chamber made of a flexible chamber (VR1) that can be changed into concave convex in the center transparent The liquid is filled and a flange VR2 is formed on the outer periphery of the chamber VR1.

In the above state, when the flange VR2 is grabbed and stretched, the focal length is changed or is changed from concave to convex or convex to concave lens.

In addition, as shown in FIG. 2, the variable mirror seals the rear surface of the circular housing 1 with the disc 4, and seals the foil mirrors 3 and 5 made of synthetic resin on the front surface of the housing 1. It is connected to the pump (9) through a fluid supply port (1 ') formed on the side of.

By supplying and withdrawing the fluid in the housing 1 through the pump 9, the thin mirrors 3 and 5 can be changed into concave or convex and flat mirror states.

Also, as shown in FIG. 3, a circular thin mirror (b) formed of a synthetic resin or a metal thin plate is fixed to a front surface thereof, and a head (d) of the flanger of the actuator inside the central portion of the thin mirror (b) is fixed. ) Is fixed, and the cylinder c of the actuator is fixed to the bottom of the housing a.

By operating the flanger of the actuator, the thin mirror b is changed into a flat, concave, and convex mirror.

However, since the variable lens of the above structure is made by filling a fluid such as water using a flexible synthetic resin, transparency may be degraded, and the shape of the lens may not properly realize the dents, and especially when used for education. The concept was similar to the concave and convex mirrors, but there was a problem that the application was inferior to the existing fixed mirrors and lenses.

In addition, the variable mirror as shown in FIG. 2 and FIG. 3 has a problem in that the education is associated with a concave. Convex mirror having a similar concept when used for education.

Accordingly, an object of the present invention is to solve the above problems by integrating optically related convex concave mirror and lens into one to increase the applicability in education, and to perform the function of concave or convex mirror and lens that are clearly distinct in function. To provide educational variable lenses and mirrors that can be.

An object of the present invention is a circular chamber having a front and a rear opening, a light source provided on an inner circumferential surface of the chamber to provide light, a half mirror plate that can be deformed to seal the front and rear surfaces of the chamber, and within the chamber. It is achieved by an educational variable lens and a mirror, characterized in that it comprises a pumping means for supplying and withdrawing transparent fluid, and a power supply for supplying power to the light source.

By using the half mirror plate and the light source as described above, the convex / concave mirror and the lens can be integrated into one, so that the applicability is increased in education, and the functions of the concave or convex mirror and the lens which are distinct in image can be performed. The integrated educational effect of lenses and mirrors can be enhanced.
