To provide a Raman microscope device with a fluorescence observation function without making the microscope more complicated and larger.SOLUTION: A fluorescence observation function is provided to a Raman microscope device with a dark field objective lens 2 attached thereto, by using a filter unit 1 including a frame body 12; a plurality of UV-LED elements 18 arranged around a window part 14 of the frame body 12, for emitting a UV light; and a long-pass filter 16 supported by the frame body 12 to close the window part 14 of the frame body 12, the filter transmitting light with a longer wavelength than that of the UV light.SELECTED DRAWING: Figure 1 【課題】複雑化・大型化することなく、ラマン顕微装置に蛍光観察機能を付与させることである。【解決手段】枠体１２と、枠体１２の窓部１４の周囲に配置されてＵＶ光を発する複数のＵＶ−ＬＥＤ素子１８と、枠体１２の窓部１４を塞ぐように当該枠体１２に支持されてＵＶ光の波長よりも長い波長を透過させるロングパスフィルター１６とを備えるフィルターユニット１を用いて、暗視野対物レンズ２を装着したラマン顕微装置に蛍光観察機能を付与させる。【選択図】 図１
