PROBLEM TO BE SOLVED: To provide an integrating sphere and a photometer allowing high accuracy measurement while preventing the degradation of measurement sensitivity without decreasing a light amount to a detector. SOLUTION: The integrating sphere 2 is used in the photometer 1 for measuring the characteristics of a measuring-object light source 100 and includes an incoming opening 22 with light from the light source 100 coming therein and a detection opening 23 with diffused light outgoing therefrom to the detector 3, the diffused light diffused on an inner wall surface 21 of the integrating sphere 2. As to this integrating sphere 2, a solid block of fluororesin is used to manufacture an integrating sphere block 2 with a spherical hollow therewithin. The outer circumference of the sphere block 2 is enclosed by reflectors 5, excluding the openings 22 and 23. COPYRIGHT: (C)2010,JPO&INPIT |
