nPL70 linear motor stage stage delivers ultrahigh stability

nPL70 linear motor stage enables high precision positioning. Z-axis positioning plays a key role in a wide variety of applications, including DNA sequencing, chip-level inspection, cell counting, photonics, and more. In autofocusing for scientific instrumentation, for example, the positioning stage needs to rapidly step the objective through a sequence of high-resolution incremental moves, while maintaining […]

How Piezo Stages React to Temperature Variation

Qualitative analysis Flexure-based piezo stages are essentially blocks of metal with flexure patterns that create a moving platform suspended from static frame via flexures. The sketch below shows a simplified flexure stage that moves in one direction when the piezo expands or contracts. A capacitive sensor is used as the feedback sensor and a preload […]
