Setting up and Adjusting a Fluorescent Microscope for Reliable Examination Results

PI Supports the GATTAscope Project

Fluorescent microscopy does not only help to make nanometer-small structures visible, but also to examine living cells and therefore explore the cell processes. In addition to preparing the sample, it is of paramount importance to set up and adjust the microscope properly to get usable results. This is exactly what the GATTAscope project is all about.

What is the Difference between a Piezo Actuator and a Programmable Piezo Shim?

New Tools for Design Engineers of Optics and Precision Mechanical Systems

PIRest is a new and unique piezo technology, where the actuator keeps its expansion without a permanently applied voltage. This leads to a simple set-and-forget alignment method without limitation of the lifetime of the actuator.

New White Paper: Piezo Tip/Tilt Systems

Design – Performance – Tuning

Piezo tip/tilt systems from PI (Physik Instrumente) are versatile positioning systems ─ they are ideal for dynamic operation in applications such as scanning, tracking, for suppressing drift oscillation or dynamic image stabilizing. Piezo tip/tilt systems and scanners offer greater acceleration and dynamic bandwidth than similar actuators such as for example, voice coil or galvanometer scanners. Piezo tip/tilt systems developed by PI are also found in applications for quasistatic positioning of optics with high demands on "pointing stability".
