During the Photonics West show, PI exhibits the pre-series of “PIShift Miniature Stages” called LPS-22, RPS-32, RPS-22 and RPS-14. They feature a very small form factor and high positioning resolution. The main component which enables the key-features is an intertial piezoelectric direct-drive motor (PIShift).

Due to their very compact form factor and the technology used, the PIShift Miniature Stages are ideal for use in vacuum to 10-9 hPa or in any application, where space is narrow. The PIShift Miniature Stages can be stacked directly to XYconfigurations without any adapter.

Time on Mars with MT-40 Space
Qualification data and guidlines for space use of ground equipments CHEMCAM is one of the 2 french contri-butions to Mars Science laboratory (MSL) instruments suite. CHEMCAM instrument functionality rely on an autofocus capability to precisely focus on the chosen target (1-9m from rover). The autofocus function is performed by a mechanism that translates the secondary mirror, with high repeatability, over the 15mm stroke and in the full applicable range of temperatures. A ground COTS translation stage ((fig.1) MICOS MT-40) has been chosen and modified to met mission requirements. This mechanism uses unusual components compared to what is chosen for high reliability space equipments in particular a screw/nut combination insuring the transmission function. It is designed to perform about 10.000 autofocus sequences during its lifetime.
