Orthogonal Decoupled Piezo Scanner
Three-axis orthogonal decoupled design with independent capacitive sensors per axis. Achieves 0.02% XY linearity and 0.08% Z linearity across the full 100 μm × 100 μm × 10 μm range. Reduces scanner bow to below 0.2 nm — one to two orders of magnitude better than tube scanners, which typically introduce 5–20 nm of background curvature.
For researchers, this means reliable step-height metrology, faithful thin-film roughness, and any measurement requiring accurate height data — without post-processing background subtraction.
Dual-FPGA Digital Controller
Hardware-level parallel processing for 3 independent feedback loops at up to 100 KHz — 3–10× faster than DSP-based systems. Two on-board lock-in amplifiers (>1 MHz bandwidth, 0.1 Hz resolution) provide zero-latency synchronous demodulation for EFM, KPFM, PFM, and other AC modes. No external lock-ins, no cabling delay.
Supports 12-channel time-synchronized data acquisition in a single scan pass — topography, phase, amplitude, lateral force, CPD, and up to 7 user-configurable auxiliaries.
Superluminescent Diode (SLD) Laser
Broadband, low-coherence SLD source (coherence length <30 μm) virtually eliminates optical interference noise between the cantilever and nearby reflective surfaces. Drives the noise floor below 50 fm/√Hz and delivers vertical resolution better than 0.1 nm (RMS <40 pm) — less than half the diameter of a water molecule.
In practice: resolves 0.39 nm SrTiO₃ atomic steps, detects sub-monolayer film nucleation, and enables piconewton-level biological force spectroscopy that conventional laser-diode AFMs cannot achieve.
Integrated Automation & Glove-Box Ready
Fully automated 4-step workflow — Parameters → Approach → Scan → Retract — with one-click auto-find-peak, auto-approach, auto laser alignment, and PSD optimization. Reduces operator dependency and learning curve, delivering repeatable results across operators.
Compact head option integrates directly into glove-boxes and cleanrooms, with controller/computer outside the chamber via feedthrough. Essential for air-sensitive samples, inert-atmosphere studies, and multi-user research facilities.
Six engineering choices that change what you can measure
Every subsystem is specified to push noise floor, precision, and throughput — the thresholds that skyrmion imaging, quantitative KPFM, and nano-mechanics actually demand.
SLD Laser Displacement Sensor
Sub-angstrom noise floor enables reliable quantification of topological Hall signatures and sub-nanometer magnetic textures that laser-diode heads cannot resolve.
Orthogonal Decoupled Flexure Scanner
XY linearity of 0.02% with capacitive closed-loop feedback removes scanner bow and axis cross-coupling — faithful quantitative mapping across the full 100 μm range.
Picometer-Class Z Positioning
Closed-loop resolution holds the tip on a single lattice site through hours of scanning — the prerequisite for atomic-step imaging and repeatable force-curve arrays.
Complete Multi-Mode Suite
Contact / Tapping / KPFM / MFM / PFM / EFM / C-AFM / SCM — software-switchable on one platform. One workflow, one control loop, no probe-holder swaps.

Over the past five years, PFM-based studies on 2D ferroelectrics have converged on three hotspots:
① Polar skyrmion bubbles — CuInP₂Se₆, Nat. Commun. (2025) · DOI:10.1038/s41467-025-57714-9
② Two-dimensional piezoelectric diodes — α-In₂Se₃, Nanoscale (2018)
③ Ultrathin HfO₂ ferroelectricity — Nature 580, 478 (2020)
Recommended workflow: (1) probe install — tapping probe; (2) sample mount — magnetic puck; (3) laser alignment — use auto-align; (4) scan params — 5×5 μm, 256×256 px, 1 Hz; (5) run auto-approach; (6) begin scan.
