LFHS2

The LFHS2 is a 2-axis ultra-high speed nanopositioner, offering a travel range up to 75µm along X and Y, a large 66mm x 66mm aperture and resonant frequencies higher than 2kHz on both axis. It can be also proposed with an integrated Z axis (50µm travel range) if required (see the 3-axis model LFHS3). This piezostage can be proposed with a coarse positioning Microstage (See our Hybrid System).

This nanopositioner is part of our high-speed product line (High power controller available). When used with the high power controller, high speed scans and step response time smaller than 2ms  are possible.
