Summary:PROBLEM TO BE SOLVED: To provide an optical spectrum measuring apparatus having a wide measurement band without lowering measurement quality.SOLUTION: An optical spectrum measuring device comprises a diffraction grating spectroscope for splitting the incident light and emitting it from a slit, a moving carriage in which a plurality of photodiode sensors having different light receiving characteristics are arranged on a plane orthogonal to a traveling direction of emitted light from the slit, and a drive mechanism for moving the moving carriage in a state in which the emitted light is incident on any one of the photodiode sensors.SELECTED DRAWING: Figure 1 【課題】測定品質の低下を招くことなく、広い測定帯域を有する光スペクトル測定装置を提供する。【解決手段】入射光を分光し、スリットから出射する回折格子分光器と、受光特性の異なる複数個のフォトダイオードセンサを前記スリットからの出射光の進行方向に直交する平面上に並べた移動台と、いずれかのフォトダイオードセンサに出射光が入射する状態に移動台を移動させる駆動機構と、を備える光スペクトル測定装置。【選択図】図１
