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. Fig. 1 Dimensional Diagram of DGM-1
