PROBLEM TO BE SOLVED: To provide an optical instrument that can ensure the output of light emission with a simple and easy structure.SOLUTION: An optical instrument 3 has: an excitation light source 14; a first optical fiber 16b that guides excitation light emitted from the excitation light source 14; and a fluorescence plate 15 that has a fluorescence part 40 that emits fluorescence with the excitation light emitted by the first optical fiber 16b, and a dichroic mirror 35 put on that side of the fluorescence part 40 which receives the excitation light. The dichroic mirror 35 allows the passage of the excitation light and reflects the fluorescence.SELECTED DRAWING: Figure 4 【課題】簡易な構造で、出射する光の出力を確保することができる光学機器を提供する。【解決手段】光学機器３は、励起光源１４と、励起光源１４から出射された励起光を導光する第１光ファイバ１６ｂと、第１光ファイバ１６ｂが出射した励起光によって蛍光を発する蛍光部４０と、蛍光部４０における励起光が入射する側の面に積層されたダイクロイックミラー３５とを有する蛍光プレート１５とを備える。そして、ダイクロイックミラー３５は、励起光を透過し、蛍光を反射する。【選択図】図４
