- Introduction
- Controllers
- Feedback
P77 piezo phase shifters are specially designed for optical detection and phase shifting applications, with travel range of up to 50μm and load capacity of up to 15kg, which is very suitable for large-aperture optical inspection equipment, like laser interferometer, for various lenses. Custom versions are available.

| Definition |
Place the PZT platform horizontally for installation, with the moving surface located above the PZT platform and parallel to the horizontal plane.
PS: Default direction for carrying capacity in the parameter table
|
Place and install the PZT platform vertically, with the moving surface parallel to the direction of gravity
|
Place the PZT platform horizontally, but the moving surface is located below the PZT platform |
