光学探头12可采用所属技术领域中常见的结构。在一个实施例中，光学探头12可包括第三光学元件121、二向色片122以及第四光学元件123。光学探头12还可优选地包括滤光片16，滤光片16可被设置在二向色片122与第四光学元件123之间，并且用以滤除激光反射光。

被测样品10被激光照射后可产生拉曼信号，拉曼信号经第三光学元件121准直后通过二向色片122。优选地，只有波长大于激光波长的光线可透过第三光学元件121。当光学探头12优选地包括滤光片16时，通过二向色片122的拉曼信号可通过该滤光片16。本领域技术人员可以理解的是，滤光片16可被设置在光谱检测设备内多个 位置中的一个，例如图1中虚线所示的位置，以便滤除激光反射光。
透过二向色片122(和滤光片16)的拉曼信号经由第四光学元件123聚焦之后离开光学探头12，并且经由狭缝131进行空间滤波之后进入第一模组13。第四光学元件123可包括聚焦透镜、镜头或镜组。上述拉曼信号经第一光学元件132准直之后射向光栅15。
