Thorlabs (Newton, NJ) announced XR-Series cross roller bearing, aluminum-bodied translation stages. The series includes rear- and side-actuated 1" travel stages and all components needed for left- or right-handed X, XY, XZ, YZ, and XYZ configurations. A dovetail feature is incorporated into the design for stacking; it could also be used to provide custom mounting options. When stacking two stages, coarse positional alignment in the axis perpendicular to stage travel is achieved by sliding the dovetail along the mating dovetail prior to lockdown. Features include less than 150 rad of angular deviation in pitch and yaw, side or end actuation with conversion between the two options, and deep and blind 1⁄4"-20 (M6) tapped holes on the moving world.
