Phase Shifter

Phase shifters are used in laser measurement to align optical path lengths. These move optics in the range of a wavelength, which corresponds to an adjustment range of less than one micrometer. It is crucial for the alignment to take place quickly and in a stable manner. For the new S-303.BL phase shifter, PI Physik Instrumente replaces classic piezo ceramic PZT actuators (made of lead titanate - lead zirconate) with pico actuators made of a crystalline, lead-free material. These pico actuators are characterized by a high linearity, so that precision positioning is also possible in open-loop operation. With a travel range of 0.3 micrometers, they achieve a precision of 6 nanometers, which corresponds to a linearity of 2%. In comparison to classic piezo ceramics, however, pico actuators have a smaller displacement. Fields of application are therefore wherever high dynamics, short travel ranges and high precision requirements are necessary.
