These adjustable mounts are designed specifically for precision positioning of diffraction gratings. The compact DGA-25 and larger DGA-50 hold 25-mm or 50-mm square or rectangular gratings respectively. Both of these mounts provide pitch, yaw, and roll, adjustments. The DGM-1 holds any of three gratings sizes having height dimensions of 12.5 mm, 25 mm, or 50 mm and provides pitch, yaw, roll, and linear adjustment. This mount is also available without rotation stage as DGM-1T. •Mounts for 12.5-, 25-, or 50-mm gratings •Pitch, yaw, roll, adjustments •CenterPoint-style mounting •All adjustments are lockable •Patent pending design Features Get To Know The DGA-25 and DGA-50 The photo collage shows the key features of the DGA-25 and DGA-50. •Top Left - Mounting for 25x25, 25x50, or 50x50-mm gratings. Newport now sells 25x25, 25x50, and 50x50-mm gratings which are compatible with both the DGA-25 and DGA-50. •Top Right - Not two, but three axes of adjustment: θx, θy, θz. Use pitch and yaw for beam alignment, use roll to set the grating lines. All adjustments are lockable. •Bottom Left: CenterPoint™ post mounting which locates the surface of the grating on the rotation axis of the mounting post. •Bottom Right: In addition to diffraction gratings, the DGA-25 and DGA-50 can hold 1” and 2” beam splitting cubes respectively, right angle prisms, and square mirrors.
