All Steel Stage Construction

UTS series linear stages feature all-steel construction with preloaded linear ball bearing slides. Steel has an almost 3-times greater stiffness than aluminum, and provides the UTS stages comparable stiffness to the popular ILS series, but in a much more compact and significantly lower profile package. The homogenous steel design minimizes thermal stress and eliminates bi-metal bending effects of aluminum stages. The result is more consistent performance than other aluminum stage designs.

Economical Stepper Motor Drive

The stepper motor version is a cost-effective solution for less demanding applications. When used with our XPS, ESP301, or SMC100PP controllers with high micro-stepping capability, low-noise operation and very small incremental motions are guaranteed. Position is attained by the number of commanded steps and micro-steps. For this purpose, the stepper motor is directly attached to the lead screw with a proprietary bellow coupling with high-torsion stiffness and no gear or belt drive in between. The high output torque of the stepper motor also minimizes the risk of lost steps and provides optimum motion sensitivity with good linearity between commanded micro-steps and the actual motion of the stage.

Vacuum Compatible Versions

The UTS-PPV6 are the vacuum compatible versions of the UTS stepper motor stage. They can be used in a vacuum environment down to 10-6 hPa. Their performance is the same as their corresponding UTS-PP stepper motor stage, except that the maximum speed is 10 mm/sec and centered load capacity is 100 N.

Diamond-Corrected Lead Screw Drive

Precision motion is provided by a diamond-corrected lead screw and a matched, lapped nut to enable high vertical load capacity and to ensure high position stability even at power-off. The precision nut includes anti-backlash preloading and a sophisticated decoupling system that prevents lead screw eccentricity errors from affecting stage movement.

Plug and Play ESP Motion Controller Compatible

The UTS is an ESP compatible stage. When connected to a Newport controller, it is quickly recognized and its operating parameters are configured without the need for user input, facilitating the startup and usability of the UTS. This Plug and Play feature is not only transparent to the use, but it also ensures the safe operation of the stage.

XY and XYZ Stage Stacks and Table Mounting

For XY configurations of UTS stages, use the M-CAP-M41 captive screws. The same screws can also be used for bolting UTS stages directly to custom mounting surfaces via thru-holes at the carriage. For mounting UTS stages to optical tables, please use the M-PBN12 base plate.

Individual Stage Metrology Report is Included

Newport guarantees specification values which are measured and recorded following ASME B5.57 and ISO 230-2 standards. The typical performance values are two times better than the guaranteed specifications.
