The PSM2 Piezo Steering Mirror Mount provides high-speed, sub-microradian resolution, tip, tilt, and z motion for mirrors, gratings and other optics. Equipped with a direct piezo actuation system without lever arm transmission, the PSM2 is ideally suited for high bandwidth laser beam steering, switching and stabilization, beam scanning, image stabilization, and laser cavity tuning. Fast and reliable motion is supplied by three multi-layer, low-voltage piezo stacks (PZT) in a right triangle configuration. The length of each piezo stack can be controlled individually. Applying a voltage to one stack, results in a tip or tilt. Changing the length of all three stacks simultaneously, results in a linear z-displacement. The tip and tilt are othogonal, with no need for coordinate transformations as required with alternative designs where the piezo stacks are placed in 120 ° intervals. The parallel motion design of the PSM2 has also the advantage of being fully temperature compensated, i.e. changes in the environmental temperature do not affect the tilting angle. PSM2 units are also maintenance-free and are not subject to wear. The PSM2 is available as an open-loop version and is ideal for applications where the position is controlled by an external sensor, e.g. a lateral effect diode, quad cell, photodiode, CCD camera, etc.Use with the 3-axis NPC3 Nanopositioning Amplifier.


PSM2压电转向镜安装提供高速，亚微米分辨率，尖端，倾斜，和z运动的镜子，光栅和其他光学。PSM2具有不需要杠杆臂传输的直接压电驱动系统，非常适合于高带宽激光束转向、开关和稳定、光束扫描、图像稳定和激光腔调谐。快速和可靠的运动是由三个多层，低压压电堆(PZT)在一个直角三角形配置。每个压电堆的长度可以单独控制。对一个堆叠施加电压，会导致顶部或倾斜。同时改变三个堆栈的长度，会产生一个线性z位移。提示和倾斜othogonal,根据需要不需要坐标转换与替代设计压电堆在哪里放置在120°的间隔。PSM2的并联运动设计还具有温度补偿充分的优点，即环境温度的变化不影响倾斜角度。PSM2也是免维护的，不受磨损。PSM2是一种开环型，适用于由外部传感器控制位置的场合，如横向效应二极管、四单元、光电二极管、CCD摄像机等，与三轴NPC3纳米级定位放大器一起使用。
