Direct Vertical Guiding

High-precision vertical motion is achieved using a direct vertical guiding system composed of matched pairs of anti-creep crossed roller bearings for the GTS30V and recirculating ball bearings for GTS70V. These linear guides were chosen to provide the straightest trajectory, smooth and precise motion and robust, long term operation. Additionally, the crossed roller bearings in GTS30V have the added advantage of more quiet, ripple-free motion, which is important in metrology level applications.

Crossed Roller Bearings

High Efficiency Drive Train

A folded DC motor with a precision ground, low-friction lead screw delivers ultra-smooth motion even at high loads. A reduction belt between the motor and the lead screw increases the available output torque and reduces servo sensitivity, ensuring 100 nm MIM.

Direct Position Feedback

Precision position feedback is supplied by a linear scale encoder, which contributes to sub-micron MIM and makes the GTS-V less susceptible to hysteresis. The direct read encoder system is impervious to position drift caused by motion-induced heating of the lead screw for improved accuracy and repeatability. For higher load applications, the GTS70VCC with a motor-mounted rotary encoder is recommended.

Plug and Play - ESP Compatible

All GTS-V stages are ESP-compatible. When connected to a Newport controller, they are quickly recognized and their operating parameters are configured without the need for user input. This Plug and Play feature is not only transparent to the user, but it also ensures the safe operation of the stage.

Manual Knob

The manual knob is convenient when the power is off and when quick and coarse adjustment is needed.

Multi-Axis Stage Assemblies

When combined with Newport motorized linear and rotation stages, the GTS-V vertical stage is a space-saving alternative to traditional stacks of stages and provides unobstructed access to the payload from any side. Furthermore, centering the payload over the bearings ensures less cantilevering load effects and Abbe induced motion errors.

Load Diagram

This loading diagram defines compliance in pitch, roll, and yaw. It can also be used to calculate off-center loads when the cantilever distance is known.

Metrology Report Included at No Additional Cost

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.

Compatible Controllers

Compatible motion controllers for the GTS-V stages are:

The maximum power consumption of the GTS-V stage is 25 W.
