  1500 Grit Ground Glass on Both Sides
  Drilled Centering Hole
  Great for Viewing Beams Exiting a Lens Tube

This frosted glass alignment disk is made from a 1500 grit Ground Glass Diffuser. The DG10-1500-H1 is Ø1" (Ø25.4 mm), and features a Ø1 mm (Ø0.04") hole drilled in the center for alignment purposes. The disk is ideal for use when viewing a beam exiting a lens tube as the beam can be seen through the ground glass. An example of this is shown in the image at the top right of this page. The disk is also available mounted in SM threaded cells in the section below.

  Mounting Cells Include Engraved Part Number, Grit, and Center Hole Diameter

Our frosted glass alignment disks are also available mounted in SM threaded cells. The 1500 grit N-BK7 diffusers are excellent alignment targets for visible beams. An incident beam can be easily seen on either side of the disk and aligned to the Ø1 mm centering hole on the Ø1/2" and Ø1" versions or the Ø2 mm hole on the Ø2" version. The SM threaded mounts allow the alignment disks to be quickly inserted or removed from an optical system without the need of retaining rings and spanner wrenches to secure the disk within a system. Please see the section immediately above for unmounted frosted alignment disks.
