Diffraction Grating Mount, Top Portion of DGM-1 Only

$Adjustable Diffraction Grating Mounts$

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.
