Pifoc piezo objective scanners
Physik Instrumente (PI) has introduced a low-cost series of fast piezo focusing devices designed to improve results in fast focusing and lens positioning as well as in deconvolution/3D imaging.
The Pifoc piezo objective scanner system packages consist of closed-loop piezomechanic objective positioners and custom-tuned compact digital servo controller/driver units.
The integrated, frictionless and high-stiffness piezo flexure drive ensures fast response and short settling times as well as high guiding accuracy, according to the company.
The digital controller is said to provide several advantages compared with the conventional analogue controllers of the fast focusing systems currently available, including higher linearity, improved settling performance, quicker adaptation to changing motion requirements and better access to advanced automation functions.
- Complete system with fast digital controller and software
- Choice of travel ranges: 100µm, 250µm or 400µm
- Sub-nanometre resolution
- Choice of position feedback sensors
The latest version of the P-736 Z-axis nanopositioning system from Physik Instrumente (PI) is designed for for high-resolution microscopy and is characterised by a large clear aperture of 160 x 110mm, high positional stability and rapid settling times.
The P-878 Dura Act Power piezo patch transducer from PI Ceramic uses an operating voltage of only -20V to +120V. As with all previous Dura Act transducers, the P-878 can be used as piezo actuator, sensor or energy harvester.
Physik Instrumente (PI) has introduced the U-264KSPA linear actuator. It is a self-locking drive that has been optimised for being produced in large quantities from engineering thermoplastics and is suitable for battery-powered or heat-sensitive applications that have a low duty cycle.
PI Ceramic has introduced a ring actuator composed of annular PICMA chip multilayer piezo actuators, which come in different dimensions and geometries and are glued together as required for scalable dimensions or travel ranges. The high-power actuators are particularly suitable for use in laser tuning, microdosing and life science applications.
Physik Instrumente (PI) has introduced an objective scanner with piezo stepping drives designed specifically for positioning microscopy applications.
