摘要
In a measuring probe (40) according to the present invention, measuring light is incident onto a single fiber (13C, 14C, 15C) before being received by a light-receiving sensor (13B, 14B, 15B) through an interference filter (13A, 14A, 15A). The interference filter (13A, 14A, 15A) is formed to obtain a transmittance characteristic corresponding to a measurement parameter, depending on a condition of an intensity distribution with respect to incidents angles of light incident onto the interference filter (13A, 14A, 15A). Thus, the measuring probe (40) according to the present invention can reduce an influence of a deviation in the transmittance characteristic due to incident angles, even with use of the interference filter (13A, 14A, 15A).
