For many examinations and microscopy techniques a movement of the sample in the Z direction, that is the optical axis of the microscope, is necessary. Often, accuracies in the range of less than 100 nanometers are required. PI offers Z stages that can be mounted to the PILine® XY stages which are suitable for the most important microscope stands and compatible with a variety of sample holders.
If samples need to be positioned with high precision in all three spatial directions, the P-545.3R8S PInano® and the P-545.3D8S PInano® offer differing specifications.
Alternatively, the microscope objective can be moved in the Z directions. PI offers many solutions for this purpose, they are labeled PIFOC. Different properties such as positioning accuracy, travel ranges, dynamics, etc. can be chosen specific to the application. An overview of the PIFOC objective scanners can be found >> under this link.
