There is one shown in No. 527. This is a cylindrical case that contains a built-in optical system for enlarging the image of the object to be observed and a light source for illuminating the object. It is formed by guiding the light through a large number of optical fibers and arranging the tips of the optical fibers in an annular shape inside the case. By irradiating the object to be observed with light from the annular light source using this optical fiber through the light guide cap, the side light (horizontal light), incident light, and transmitted light are appropriately combined, allowing for good observation. It looks like this.

It consists of a shadowless illuminator 5 connected to the tip of the case 2. In this example, a CCD element is also built in as an imaging means 6 that captures the image obtained by the optical system 3, and the signal is transmitted to the outside of the figure. The signal is sent to an observation display (not shown) via a signal processing means, and this observation display displays 50
It is now possible to observe magnifications ranging from 1 to 1,000 times.

。The shadowless light body 5 includes a hemispherical shadowless light forming part 14 in which a through hole 13 for the image light of the object M is bored in the center, and an objective tip part 15 that is the open side of the hemisphere. It is made of highly transparent synthetic resin, such as acrylic resin (methacrylic resin). The shadowless light forming part 14 is arranged at the tip of the case 2 so that the outer surface, that is, the outer surface of the spherical surface faces the light source 4 and the irradiation light from the light source 4 hits the outer surface of the shadowless light forming part 14. More specifically, the shadowless light body 5 is supported by a support member 16 formed so as to cover the outside of the shadowless light forming section 14, and this support member 16 is screwed onto the tip of the case 2. Focusing, which will be described later, is performed in this screwed state.

面が合うようにするためのものである。This shadowless illumination body 5 refracts the irradiated light from the annular light source 4 at the hemispherical shadowless light forming part 14 to create shadowless light, that is, the three-dimensional structure of the observed part of the object M. This is to obtain a state in which the irradiation light is applied from all directions on a hemispherical surface so as to prevent shadows from forming on the surface of the object. This is to align the surface of the object M to be observed with the focus of the objective lens of the system 3.
