Piezoelectric xy stages | Laser Focus World

The P730 and P731 monolithic flexure stages are piezoelectrically driven with 50 50 and 100 100?m motion ranges, respectively. The resonant frequency of 400 H¥allows fast scanning for nearfield scanning microscopy. Basic models are offered in aluminum. Stainlesssteel and Invar versions are available.

Tracks of heavy ions 'imprinted' in lithium fluoride crystals. At the top, spot tracks observed under a fluorescence microscope in plates perpendicular to the heavy ion beam. At the bottom, the ion tracks in the parallel oriented plate (the blurring at both ends of the trace is an artifact of the depth of focus of the microscope). False colors.

Lithium fluoride fluorescent crystals track high-energy heavy ions such as iron

In comparison to previous crystals such as aluminum oxide, LiF crystals also require a less expensive microscope for analysis.
