The TTR001(/M) Tip, Tilt, and Rotation Stage provides ±5° uncoupled tilt adjustment in pitch and roll, together with ±10° rotation (yaw) adjustment. These adjustments allow optical components and fixtures to be aligned with a plane and then rotated within that plane. The center of roatation axis is located at a line normal to the center of the platform. Both the tip and tilt axes will move with respect to a point located 12 mm below the top surface of the stage on the rotation axis. The top plate features an array of 21 8-32 (M4) threaded holes on a 1/2" (12.5 mm) pitch. An 8-32 to 6-32 thread adapter is included with imperial stages for use with the PM3(/M) and PM4(/M) clamping arms sold below.

The high-resolution Mitutoyo micrometers incorporated into the stage are marked with a 0.001" (10 µm) scale and provide positioning accuracy within 5 arcseconds. Turning the micrometers gives 1.5° of rotation and 1.78° of tilt per revolution. Preload adjustment to eliminate backlash can be performed by adjusting the knobs adjacent to the micrometers as shown above. One knob adjusts/locks the pitch (Θx) and roll (Θy) axes simultaneously, while the other knob adjusts/locks the yaw (Θz) axis. Note that if the knob is tightened, the motion in that axis is effectively locked until the micrometer is backed off. In this case, some friction may be experienced when adjusting the remaining axis.
The stage is fixed to the work surface via three clearance holes for standard 1/4"-20 (M6) screws. The deck height of the stage is 1.48" (37.5 mm). A Height Adapter Plate [TTR001SP1(/M)] is available to raise the deck height to the standard 2.46" (62.5 mm), making the stage compatible with our NanoMax, MicroBlock, and RollerBlock 3-Axis Stages. The height adapters are fixed to the work surface using the four clearance holes that accept standard 1/4"-20 (M6) screws. The stage is then mounted to the height adapter using the three 1/4"-20 (M6) tapped holes.
A typical application is shown to the right, where the TTR stage is raised up to mate with a MAX311D 3-axis stage. A PM4 clamping arm is used to mount a prism on the tip, tilt, and rotation stage. An HCS013 Mount and RMS09 adapter are mounted on the MAX311D stage and used to hold a collimating lens with connectorized fiber. The collimated laser beam is directed onto the prism, and the laser refraction is adjusted via the TTR001 stage micrometers.
