The DGM-1 is designed specifically for precision positioning of diffraction gratings. This mount is capable of holding square or rectangular gratings having dimensions of 12.5 mm, 25 mm, or 50 mm, all 6-mm-thick. Its unique clamp design allows the grating, regardless of size, to always sit at the center of rotation of the mount. Four degrees of freedom are provided to achieve ideal alignment. Angular adjustments pitch and roll are driven by two precision 100-TPI threaded screws, and a linear x-axis adjustment allows the grating to be located right at the center of yaw rotation. All adjustments are lockable. The DGM-1 is supplied with two BR-U clamps to allow mounting to an optical table top.

DGM-1是专门为衍射光栅的精确定位而设计的。这种安装能够容纳大小为12.5 mm、25 mm或50 mm的正方形或矩形光栅，所有这些光栅都是6 mm厚。其独特的夹具设计，使光栅，无论大小，始终坐在旋转中心的安装。提供四个自由度，以实现理想的对齐。角度调整螺距和轧辊由两个精密的100 tpi螺纹螺丝驱动，线性x轴调整使光栅位于偏航旋转的正中心。所有调整都是锁定的。DGM-1配有两个BR-U夹头，可安装在光学台面上。
