New super-resolution techniques, such as stimulated emission depletion microscopy, photoactivated localization microscopy, and stochastic optical reconstruction microscopy, have reduced resolution from 100–200 nm even lower.
Nanometer resolution piezoelectric objective positioners are ideal for these applications. Alignment of microscope and sample holder requires precise, fast movements. The piezoelectric objective lens positioner based on high-resolution piezoelectric ceramic drive can provide unique ultra-precision technical support.
The P72 series piezoelectric objective lens positioner is specially designed for microscope applications. It is designed with a non-hysteretic flexible hinge parallel guide mechanism. It is frictionless and has extremely high resolution, small compensation amount, and ultra-high focusing stability. It is very suitable for Applications such as sample adjustment, beam alignment and beam tracking.
Features: Z-axis motion, 100μm stroke, 2.5nm resolution, no-load harmonic frequency 350Hz, no-load step time 3ms.
The P72 series piezoelectric objective lens positioners are small in size and compact in structure, and can achieve a displacement stroke of 100 μm. It is connected to the top of the lens through a thread adapter, and the thread can be selected arbitrarily. It can be adapted to a variety of standard lenses such as Olympus, Zeiss, Nikon, and Leica, and can be customized.
The no-load resonant frequency can reach 350Hz, and it can carry a 200g load for high-speed precision motion, which has been widely used in optical scanning, confocal microscopy and other fields.
