摘要

This invention relates to a measuring probe 40, the measurement light has a first diffusion plate 19 scattered by and , when the film through a plurality of interference filters (13A, 14A, 15A) to be received by the plurality of light receiving sensor (13B, 14B, 15B), each interference through the second diffuser plate (13C, 14C, 15C) the film enters the filter (13A, 14A, 15A). Then, the interference film filter (13A, 14A, 15A) is , in accordance with the interference film filter (13A, 14A, 15A) for the condition of the intensity distribution of incident light to the incident angle , corresponding to the measured parameter so as to obtain a transmittance characteristic is formed . As a result , the measuring probe 40 of the present invention while using the interference film filter (13A, 14A, 15A),, the effect of the displacement of the transmission characteristics due to the incident angle can be reduced .
