摘要:
In a measuring probe (40) according to the present invention, measuring light is split into a two or more through a split optical system (12), and, when each split light is received by a light-receiving sensor (13B, 13B, 15B) through an interference filter (13A, 14A, 15A) serving as a color filter, the split light is introduced into the interference filter (13A, 14A, 15A) through a collecting lens group (123C, 14C, 15C) formed as a substantially bilateral telecentric system. 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 on 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 using the interference filter (13A, 14A, 15A).
