The model HT 03-LM vertical positioning stage offers a travel of 3mm with accuracy of 2um and repeatability of 20nm, making it ideal for wafer positioning.

New from Steinmeyer FMD Division, the model HT 03-LM vertical positioning stage offers a travel of 3mm with accuracy of 2um and repeatability of 20nm, making it ideal for wafer positioning.

A compact piezo linear motor is used to drive a 10:1 ratio wedge.

Precision crossed roller bearings ensure smoothness of motion and high rigidity.

Manufactured from stable aluminium alloy, the HT 03-LM weighs only 3.6kg, but can handle loads up to 200N.

Maximum speed is 25mm/s and position feedback is provided by a precision linear encoder with 0.1um resolution.

Extra cost options include preparation for high vacuum and clean room operation.

This stage is ideal for applications in the semiconductor, fibre optic, medical/life sciences, optical, laser systems and robotics industries.
