Claims

[Scope of utility model registration request]

(1) A substantially spherical lens body having a hemispherical surface at one end and a flat surface at the other end is formed, and this lens body has a refractive index of n=1.9±0.6 for electromagnetic waves such as light. 1. A magnifying glass, characterized in that it is made of a transparent or translucent material within a range of approximately uniform shape, and the flat surface is set inside the focal point of the lens body.

(2) Form a substantially spherical lens body having a hemispherical surface at one end and a flat surface at the other end, and set this lens body to a range of refractive index n=1.9±0.6 for light, etc. The flat surface is set inside the focal point of the lens body, a fixed frame is attached to the other end, and the flat surface inside the fixed frame is formed of a certain transparent or semi-transparent material. A magnifying glass characterized by having a gap in its part.
