The TB positioner series features compact construction and high load capacity. The ball bearing guides are bedded directly in the stainless steel base structure for exceptional guiding accuracy. Compression springs minimize backlash. These positioners can be attached, using the threaded connectors, for use as an XY-combination. Mounting angles are available for the Z-axis. Thanks to the large clear aperture on the positioners, they can also be used for adjustment of optical elements in the beam path.
