COLORIMETER USING OPTICAL FIBER AND SMALL INTEGRATOR

摘要

A color measuring apparatus by using an optical fiber and a small equator is disclosed. In the color measuring apparatus, light from a light source(1) is irradiated to a measuring sample through an optical fiber bundle(3) and is transmitted to a equator(4) so that a reflected light is multi-reflected in the equator(4). An inside of the equator(4) is coated by a material having a high reflexibility. Some illuminance of a surface of equator(4) which is multi-reflected and leveled in the equator(4) is again transmitted to a spectroscope(2) via optical fiber bundle(3).
