Adjustable Diffraction Grating Mounts
Adjustable Diffraction Grating Mounts
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

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.
DGM-1 Provides the 4th Degree of Freedom
The DGM-1 has four degrees of freedom to achieve ideal alignment. Its extra degree of freedom, linear translation, allows gratings with different thicknesses, to always be positioned to sit right at the center of yaw rotation.
