ABSTRACT:
A light spectrum measuring apparatus comprises a sensor case on which a window with a glass is provided; a light emitting member and a light receiving member both provided in the case so that light emitted from the light emitting member passes through the glass, is reflected from solution, returns in the case, and is received by the light receiving member, wherein the glass, the light emitting member and the light receiving member are arranged in such a positional relation that positive reflected light which is emitted from the light emitting member and directly reflected by the glass without proceeding in the solution, is not received by the light receiving member.
