The piezoelectric microscope objective lens shifter launched by IdealPhoton is a high-precision focusing device driven by piezoelectric ceramics. It achieves axial (Z-axis) micro-displacement of the objective lens through nanoscale steps (such as 0.1nm resolution) and fast response (millisecond level). It is suitable for fields such as super-resolution microscopy and live cell imaging that require real-time precise focusing.Sub-nanometer closed-loop positioning (such as ±1nm repeatability), frictionless silent movement and anti-electromagnetic interference design, combined with large load (>200g) and long life (>10^9 cycles), significantly improve the three-dimensional imaging stability of the microscope system
