Abstract: A grating drive apparatus (100) for use in a multiple-grating spectrometer (500) is provided. The spectrometer has an entrance slit (521), an exit port (550), an optical path (525) between the entrance slit and the exit port, and a plurality of diffraction gratings (237-239). Each of the gratings is rotatable about a respective preferred axis for selecting a wavelength during spectrometer operation. The grating drive apparatus includes a turret (200) having a plurality of gratings mounted on it, a mechanical stop assembly (300), and a drive assembly (400). The drive assembly causes the turret to engage the stop assembly to rotate the turret and select a grating. The drive assembly also rotates the selected grating to select an operational wavelength.

Abstract translation: 提供了一种用于多光栅光谱仪（500）的光栅驱动装置（100）。 光谱仪具有入口狭缝（521），出口（550），入口狭缝和出口之间的光路（525）和多个衍射光栅（237-239）。 每个光栅可围绕相应的优选轴线旋转，用于在光谱仪操作期间选择波长。 光栅驱动装置包括具有安装在其上的多个光栅的转台（200），机械止动组件（300）和驱动组件（400）。 驱动组件使转台接合止动组件以旋转转台并选择光栅。 驱动组件还旋转所选择的光栅以选择操作波长。
