Rotary positioner
360° Thorlabs

The XYR1 is a low profile XY axis translation stage with continuous rotation about the Z axis. The central SM1-threaded through-hole allows the stage to be used in an imaging application that requires illumination from underneath the sample. The stage contains an array of 1/4"-20 (M6) and 8-32 (M4) tapped holes for mounting samples and components. In addition, the stage has eight 4-40 tapped holes around the central through-hole so that it can be used with Thorlabs' 30 mm or 60 mm cage system without the use of adapters.

The X and Y axis micrometers on the translation stage have a travel range of 1/2" (13 mm). An engraved angular scale along the outer edge of the stage's mounting surface allows the user to set the angular orientation of the stage, which can then be fixed using a locking setscrew. Locking the rotation axis does not prevent translation along the X and Y axes. To prevent attached components from interfering with the stage's rotation or translation, the top surface of the rotation platform is above the frame of the XYR1.
