<p>PROBLEM TO BE SOLVED: To increase light receiving amount in an optical measurement equipment of a light scattering object which uses optical waveguides, and improve measurement precision. SOLUTION: A light from a halogen lamp 22 is turned into a light having a specified wavelength by an interference filter 24, and introduced into each optical fiber of an optical fiber group 14a for projection, by a condenser lens 26. One end of an optical fiber waveguide 10, the other end of which is closely brought into contact with a measurement object 20, is branched into three optical fiber groups, i.e., an optical fiber group 14a for projection, and a first and a second optical fiber groups 16a, 18a for light receiving. Each of the optical fiber groups 14a, 16a, 18a is formed by bundling optical fibers of each unit bundle. Each unit bundle contains the optical fiber for projection arranged in the center, the first optical fiber group for light receiving which is arranged, around the fiber for projection, almost on a circumference of a first circle setting the fiber for projection as a center, and the second optical fiber group for light receiving which is arranged almost on the circumference of a second circle whose radius is larger than that of the first circle.</p> |
