Products

• DriveAFM: A tip-scanning research atomic force microscope for work in air and in liquid, from single molecules and virus capsids to 2D materials and semiconductors. CleanDrive photothermal cantilever excitation keeps operation stable in liquid and enables WaveMode off-resonance imaging.
• FlexAFM: A mid-range tip-scanning research AFM that can be run stand-alone, on an inverted optical microscope or inside a glovebox. It handles large samples and takes a wide set of sample holders and add-ons, and its accessories carry over to the DriveAFM on upgrade.
• CoreAFM: A compact all-in-one research AFM that brings the scanner, XYZ sample stage, camera, active vibration table and airflow shielding into a single unit. It runs in air and in liquid and can be extended with more than 30 optional modes and functions as the work changes.
• Alphacen 300 Flex: An industrial AFM built around the Flex-Mount tip-scanning head for samples that are too large or too heavy for a normal microscope. A dedicated acoustic enclosure cuts external noise, and extra translation or rotation axes can be added for awkward geometries.
• Alphacen 300 Drive: An AFM metrology system for 300 mm wafers, aimed at Angstrom level surface roughness and dimensional measurement in semiconductor quality control. WaveMode photothermal off-resonance imaging raises the line rate while holding tip sharpness, and wafer edge and sidewall inspection is supported.
• LensAFM: An AFM that mounts on the objective turret of an upright optical microscope or 3D profilometer, so a region found optically can be measured at nanometre resolution by rotating the turret. It returns 3D topography and can also map electrical, magnetic and mechanical properties.
• Nanite: One of the smallest AFM scan heads Nanosurf builds, made to be integrated into custom stages, production lines or existing setups. It measures sub-nanometre surface roughness on workpieces that cannot be cut down, including concave and curved surfaces.
• Flex-Mount: The FlexAFM research scan head in a mountable form, made to be attached to a large motorised translation stage or to a customer stage. The tip-scanning design keeps performance on samples whose weight and size would defeat a sample-scanning instrument, including curved parts.
• NaioAFM: An all-in-one entry level AFM for teaching and basic research on small samples, combining scan head, controller, XY table, airflow shielding and vibration isolation in one unit. No laser alignment is needed, so a first measurement can be made within minutes of unpacking.
• NaioSTM: A tabletop scanning tunnelling microscope with scan head and controller in one instrument, widely used for teaching. The very short mechanical loop gives enough stability to reach atomic resolution on HOPG in an ordinary classroom, and tips are simply cut from Pt/Ir wire.
• Industrial AFM Solutions: Bespoke AFM systems engineered around a customer sample and measurement requirement, using mountable FlexAFM or DriveAFM scan heads on purpose-built stages. They are used for sub-nanometre characterisation of polished concave and convex glass, large optics and production quality control.
• AFM Glovebox Workstation: A turn-key package that integrates a FlexAFM or DriveAFM into a high performance glovebox for air sensitive samples. The table, frame and vibration damping are reinforced to hold AFM performance against glovebox pump noise, and the instrument is driven from software outside the box.
• Stage Solutions: Nanosurf lists Stage Solutions among its industrial AFM offerings as customised stage systems built around a customer's requirements. The published page names manual and motorised stages with up to five axes, safety integration, customised AE, software integration and automation. Applications given are production scale quality control and production scale research and development, sub-nanometre surface characterisation of highly polished concave and convex glass, and large optics for short wavelength applications and synchrotron mirrored surfaces.
• 150 um Z Petri Dish Holder: A Petri dish holder with a 150 um z actuator, used for long range force spectroscopy on cells and tissue in liquid. Dishes are held by magnetic clamping and the holder can be heated to 60 degrees C when paired with the CH1 temperature controller.
• Acoustic Enclosure AE1100: A large acoustic enclosure sized to take an AFM together with a standard inverted optical microscope. Three window elements of acoustic isolation glass give access from three sides, while the back and top panels use an acoustic isolation sandwich.
• Acoustic Enclosure AE350: A compact acoustic enclosure for the CoreAFM or for an Isostage 300 based FlexAFM or DriveAFM. A multilayer acoustic isolation sandwich and an acoustically isolating cable feed-through cut the airborne noise that reaches the instrument during a scan.
• Acoustic Enclosure AE550: A large acoustic enclosure for standard Nanosurf AFM systems and small custom stage systems. It uses a multilayer acoustic isolation sandwich with an acoustically isolating cable feed-through, and can be upgraded with a temperature control system.
• Advanced Humidifier: A water column with active flow rate and humidity control for measurements that need a set relative humidity. Humidified air is mixed with dry air to hold the target value, and the tubing feeding the experiment is heated to stop condensation forming.
• Basic Humidifier: A washing bottle with a frit that humidifies gas passively before it reaches the AFM sample space. Gas is fed from a cylinder or wall connection through a flow rate valve, and the humidity reached is set by flow rate alone rather than by active control.
• Cantislide Cantilever Holder with/without Alignment Chip: A cantilever holder for the FlexAFM and CoreAFM, supplied with or without an alignment chip. The alignment chip version places the cantilever in a fixed position so the laser does not have to be realigned after an exchange, which saves time between samples.
• Conducting Atomic Force Microscopy (C-AFM) Sample Holder: A sample holder with a current amplifier built into it, for conductive atomic force microscopy. It reads tip currents over a fixed range of plus or minus 25 nA and can be combined with the Environmental Option for measurement under controlled atmosphere.
• Conical Cantilever Holder: A conical cantilever holder for the DriveAFM, made from ceramic or PEEK. Conductive, non-conductive and HV-PFM versions are offered, the last giving direct electrical contact to the tip for piezoelectric force microscopy at raised voltage.
• Digital Inverted Microscope Option (DIMO): A digital optical microscope built into the Isostage 300 vibration isolation platform, giving a view of the sample from below without a separate inverted microscope. It works in transmitted light and accepts a filter cube for basic fluorescence imaging.
• DriveAFM Camera: A top view camera for the DriveAFM on a magnetic kinematic mount, used to find the area of interest and watch the cantilever during approach. It carries adjustable Koehler-like sample illumination and sends images over USB 3.0.
• DriveAFM Signal IO Board: A breakout board that brings digital and analogue signals out of the DriveAFM controller on standard connectors. It is used for developing new measurement modes and for wiring the AFM to external instruments such as lock-in amplifiers or source meters.
• EC Cell: An electrochemical cell for electrochemical AFM and scanning electrochemical microscopy. It provides electrical contact to the sample, two wire electrodes and two reference electrodes, and is supplied with a PEEK or PVDF insert and the Environmental Option.
• Environmental Option: An environmental ring and sealing membrane that close off the sample space around a Nanosurf sample holder. This lets a measurement run under a chosen gas atmosphere or humidity while the scan head still reaches the sample.
• FlexAFM / CoreAFM Signal IO Board: A breakout board that brings digital and analogue signals out of a FlexAFM with C3000i controller or a CoreAFM. It is used for developing measurement modes and for connecting external instruments into the AFM signal path.
• FlexAFM Camera: A camera module giving both top and side views of the sample on FlexAFM systems, with adjustable illumination. Laser alignment is carried out through the module, and three digital zoom stages help when positioning the tip on a small feature.
• FluidFM Add-on: A microfluidic add-on for hollow cantilevers that carry an opening at the tip, so fluid can be injected or drawn in at a chosen point. It is used to inject or extract material from single cells, for colloidal spectroscopy with interchangeable beads and for single-cell force spectroscopy.
• FluidFM Cantilever Holder: A cantilever holder that carries Cytosurge FluidFM probes on the FlexAFM and CoreAFM. It routes the fluidic connection through to the hollow cantilever so the probe can be used for spotting, injection and extraction.
• FluidFM Cantilever Holder for DriveAFM: A cantilever holder that carries Cytosurge FluidFM probes on the DriveAFM. It routes the fluidic connection through to the hollow cantilever for spotting, injection and extraction work on single cells.
• Heater-Cooler Sample Holder: A sample holder that both heats and cools, covering minus 35 to 180 degrees C with the CH1 temperature controller and a separate pump unit. It stacks with the Environmental Option and the EC-Cell for work under controlled atmosphere or in electrolyte.
• Heater Sample Holder: A resistively heated sample holder covering ambient temperature to 250 degrees C, driven by the CH1 temperature controller. It is used for studying phase changes, annealing and temperature dependent mechanical behaviour under the AFM tip.
• High Voltage Amplifier and Sample Holder: A ten times voltage amplifier with a matching sample holder for piezoelectric force microscopy. It takes the fixed plus or minus 10 V output of the controller and delivers plus or minus 100 V to the sample, which is what stiff ferroelectric materials need to switch.
• IMO Stage to Isostage300 Adapter: An adapter that allows an inverted microscope option stage to be mounted on the Isostage 300 vibration isolation platform. One stage then serves both the microscope setup and the stand-alone setup, which avoids buying a second stage.
• Isostage 300: A compact vibration isolation platform sized to carry a Nanosurf scan head together with large accessories and sample holders. Spike-Guard detects scan lines affected by uncompensated vibration and rescans them, so a disturbance does not spoil the image.
• Isostage 400: An active vibration isolation platform for inverted optical microscopes and small custom stage systems. Its 400 by 500 mm top plate leaves room for a microscope body with an AFM head above, and it carries loads up to 120 kg.
• Manual XY IMO Stages: A manual sample stage for AFM systems coupled to an inverted optical microscope. Sample translation runs parallel to the optical path so the optical view stays centred, and objectives can still be mounted in every revolver position.
• Manual XY Stage: A manual sample translation stage for stand-alone FlexAFM and DriveAFM systems. It gives 20 by 20 mm of travel on a 300 mm square base plate, so a region of interest can be brought under the tip by hand between scans.
• Motorized XY IMO Stages: A motorised sample stage for AFM systems coupled to an inverted optical microscope, driven by a stick-slip piezo motor. Translation runs parallel to the optical path so the optical view stays centred, and positions can be revisited from the software.
• Motorized XY Stage: A motorised sample translation stage for stand-alone FlexAFM and DriveAFM systems, giving 20 by 20 mm of travel. Measurement positions can be set and revisited from the control software, which is the basis for automated measurement series.
• Non-Translating Stage: A fixed sample platform for FlexAFM systems where sample translation is not required. It replaces the XY stage with a rigid 300 mm square plate, which suits routine measurements that always sit at the same position on the holder.
• Petri Dish Holder: A holder that takes 35 and 50 mm Petri dishes with magnetic clamping, for AFM work on cells and tissue in liquid. Heating to 60 degrees C is available with the CH1 controller, and the DriveAFM version also allows perfusion and environmental control.
• Rigid Steel Table 750 mm x 750 mm: A stable steel table with a CleanBench tabletop, sized for the Acoustic Enclosure AE350. It is supplied as a disassembled frame with the tabletop separate, and carries a CoreAFM, FlexAFM or DriveAFM inside the enclosure.
• Rigid Steel Table 900 mm x 1200 mm: A stable steel table with a CleanBench tabletop, sized for the Acoustic Enclosure AE1100. The larger top takes a FlexAFM or DriveAFM together with an inverted optical microscope, and it is delivered as a disassembled frame.

It uses a 10 inch SMA to SMPM cable and works with the separate SMM source and receiver unit, which supplies the microwave signal.
• Scanning Spreading Resistance Microscopy (SSRM) Module: A logarithmic transimpedance amplifier with matching sample holder for scanning spreading resistance microscopy. Its single logarithmic range covers 1 pA to 5 mA, which is what is needed to map carrier concentration across a doped semiconductor cross section.
• Scanning Thermal Microscopy (SThM) Cantilever Holder: A cantilever holder for AppNano thermal probes, used for scanning thermal microscopy on the FlexAFM and CoreAFM. It brings the probe resistance out to the readout electronics so local temperature and thermal conductivity can be mapped.
• Seismion Reactio: An active vibration isolation table for inverted optical microscopes and small custom stage systems. The 500 by 400 mm top plate suits a microscope body with an AFM head above, and it carries loads up to 80 kg.
• Small Volume Cantilever Holder and Perfusion Chamber: A cantilever holder with an integrated perfusion chamber that allows AFM measurement in a liquid volume of 250 microlitres. Fluid is exchanged through the ceramic platform during the experiment, and the silicone sealing membrane tolerates acids used for cleaning.
• VertiSense Scanning Thermal Microscopy (SThM): A readout unit for AppNano scanning thermal microscopy probes that adds thermal imaging to a Nanosurf AFM. It is used to map local temperature distribution and variations in thermal conductivity across a sample surface.
• Temperature Controller CH1: A temperature controller for Nanosurf sample holders with variable temperature. It reads two sensors, a PT100 for control and an NTC for monitoring, and drives both resistive and Peltier based heating elements.
• Tip Access Module: A module that brings a direct electrical connection out to the cantilever tip on the DriveAFM through an SMA connector. Either external ground or scan head ground can be selected, which matters when an external source or measuring instrument is wired in.
• Tip Current Module: A linear current amplifier for the DriveAFM with three switchable gain stages, covering plus or minus 0.5 mA down to plus or minus 50 nA. It suits conductive AFM where the current range varies between samples, and offers external or scan head grounding.
• Variable Magnetic Field Sample Holder (VMFSH) and Controller: A sample holder and controller that apply a variable magnetic field during measurement, used mainly for magnetic force microscopy. The in-plane field reaches about 780 mT at a 2 mm gap, and the field can be stepped in increments of 0.001 mT.
• WaveMode Cantilever WM0.1Au-SS: A silicon nitride probe for photothermal off-resonance tapping in WaveMode, with a gold coating on the reflex side tuned for photothermal excitation. The paddle shape limits reflective interference from the sample and raises the sum signal. It works in air and in liquid.

Distance measuring tools allow angles and distances to be measured directly on the acquired image.
• Naio Control Software: Naio Control Software drives Nanosurf's Naio instruments through the same intuitive platform used across the company's AFM range. Selecting the cantilever triggers an automatic, parameter free frequency sweep before approach, removing the need to set tuning parameters by hand. Further usability features cover a spectroscopy wizard, automated deflection calibration, beginner and advanced layouts, a mode aware configurable graph area, and file handling with naming conventions, Windows Explorer integration, an image gallery and bulk renaming. Updates are released regularly at no cost and the software can be installed on any number of computers for analysis.
• Nanosurf Python Scripting Interface: Nanosurf control software publishes its functionality through a COM interface by running an instance of a COM Automation Server, which COM Automation Clients can query at runtime and then call. Those functions are reachable from most modern programming languages, among them Python, C++, C#, VBS, Matlab, JS and LabView. Nanosurf has built a Python API on top of this so that routine tasks can be automated and custom experiments and workflows written as Python scripts. The Nanosurf Python package is installed from PyPI with pip install nanosurf, and a Programmers Manual and Python Library Overview are available as documentation.
• Nanosurf Studio: Nanosurf Studio is the control and analysis software for the DriveAFM, and it reworks the look and feel of AFM control with a browser-like experience and scrollable tabs for multi-screen operation. It suits novice and expert scanning probe microscopy users alike, and quarterly releases add features, improved workflows and bugfixes. AutoAlign uses the DriveAFM's full motorisation to align the beam deflection and photothermal excitation optics with one click, while ViewPort handles visualisation and navigation across many orders of magnitude, covering AFM measurements, camera feeds and other image data, and allows AFM and optical images to be overlaid in a correlative workspace. User interface layouts can be set up individually, AFM setup is automated, and instrument control is fully scriptable.
