The DGM-1T is the top portion of the original DGM-1 Diffraction Grating Mount. 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 to always sit at the center of rotation of the mount. 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.

DGM-1T是原DGM-1衍射光栅支架的顶部部分。这种底座能够容纳尺寸为12.5毫米、25毫米或50毫米的正方形或矩形光栅，所有这些光栅都有6毫米厚。其独特的夹具设计，使光栅始终坐在旋转中心的安装。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。所有调整均可锁定。
