Features

• 180° of Discrete or Continuous Positioning
• Lockable at 13 Locations, at 15° Increments, Using Included Linchpin
• Arrangement of Mounting Options as Seen in Figures 1.1 and 1.2

Thorlabs' Adjustable Angle Mounting Plate provides a full 180° of movement at 15° increments with ±18 arcmin precision. The mounting platform can be positioned at 13 discrete positions utilizing the included linchpin. Engravings on the mount denote the angular positions possible and the associated pin location for each position. In addition to the 13 discrete positions available, the plate can be oriented at any angle by tightening the hex locking screw.

The mount has a maximum load of 35 lbs (15.8 kg) at the 60° inclination setting when using the linchpin. The load capacity is limited to 8 lbs (3.6 kg) if the linchpin is not used. This adjustable angle plate contains an array of 1/4"-20 (M6) mounting holes and 1/4" (M6) slots on the top and bottom plates as shown in Figures 1.1 and 1.2.

To change the angle between the two plates, loosen the 1/8" (3 mm) hex locking screw located on the back of the mount (see Video 1.4). Once the hex screw is loose, remove the locking pin. Rotate the top plate until the engraved white line on the top plate hinge matches up with the desired angular marking on the bottom plate hinge. Insert the pin into the slot indicated by the letter in parentheses next to the angular position you selected. For example, to secure the top plate at 45° past vertical as shown in Figure 1.3, the pin must be inserted into the A slot. Once the pin has been inserted, tighten the hex locking screw to fully secure the position of the mount.
