Abstract

PURPOSE:To measure the transparency of a sample such as human skin, whose transmittance cannot be measured as a matter of fact, highly accurately, by constituting an apparatus with a light source part, a light receiving part, a light screening part, a cover plate and a light measuring device, and transmitting the light. CONSTITUTION:The basic structure of a measuring apparatus is composed of the following parts: a cylindrical light screening body 1; a light source part 2, which is provided at the upper part of a light screening body 2; a light receiving part 3; a circular cover plate 4, which is provided at an opening part at the lower end of the light screening body 1; and a light measuring device, which is linked to the light receiving part 3. Light is projected on a sample from the light source part 2 and reflected from the sample at a position (the position of a small opening part 6 when the cover plate 4 is attached) corresponding to the light receiving part 3. The light receiving part 3 receives the reflected light. The reflected light, which is received with the light receiving part 3, is measured with the light measuring device, which is linked to the light receiving part 3. Thus the reflectivity of the reflected light from the sample is measured.
