Dualaxis scanning mirror | Laser Focus World

A dualaxis aircooled scanning mirror called TOM is a single mirror driven by analog signals that scans two axes at 100H¥rates. Designed for use with highpower lasers (u¥to 15 kW), TOM is suitable for surface hardening, marking, cutting, and welding applications. Angular mirror positions are read in real time by an internal optical sensor.

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.

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