    • A high-bandwidth SPM tip scanner includes an objective (34) that is vertically movable within the scan head to increase the depth of focus for the sensing light beam. Movable optics permit targeting of the sensing light beam on the SPM's probe (12) and permit the sensing light beam to track the probe during scanning. The targeting and tracking permit the impingement of a small sensing light beam spot on the probe (12) under direct visual inspection of focused illumination beam of an optical microscope (32) integrated into the SPM (10) and, as a result, permits the use of a relatively small cantilever with a commensurately small resonant frequency. A high-bandwidth tip scanner constructed in this fashion has a fundamental resonant frequency greater than greater than 500 Hz and a sensing light beam spot minor diameter of less than 10 μm.
    • 高带宽SPM尖端扫描器包括可在扫描头内垂直移动的物镜(34),以增加感测光束的聚焦深度。 可移动光学器件允许在SPM探头(12)上瞄准感测光束,并允许感测光束在扫描期间跟踪探头。 瞄准和跟踪允许在集成到SPM(10)中的光学显微镜(32)的聚焦照明光束的直观目视检查下在探针(12)上碰撞小的感测光束点,结果允许 使用具有相当小的谐振频率的相对小的悬臂。 以这种方式构造的高带宽尖端扫描器具有大于500Hz的基本谐振频率和小于10μm的感测光束光点小直径。
