    Description

    The MultiMode AFM design allows different modes applications.

    Specifications

    Scanner Piezo Resolution: 16 bits (all axes)

    Scanner size (X, Y axis): Scanner "J" - 100 µm; Scanner "E" - 10 µm; Water-Cooled Scanner - 125 µm

    Vertical range (Z axis): Scanner "J" - 5.5 µm; Scanner "E" - 3.5 µm; Water-Cooled Scanner - 5 µm

    Noise: <3Å in vertical (Z) dimension with vibration isolation

    Lateral resolution: The radius of curvature of the end of the tip will determine the highest lateral resolution obtainable with a specific tip. The sidewall angles of the tip will also determine its ability to probe high-aspect-ratio features.

    Typical accuracy: 1%

    Maximum accuracy: 2%

    Orthogonality: 2 degrees

    Max. sample size: Samples up to 10 mm diameter and 6 mm thick

    Small samples* : Magnetic holder is available for mounting small samples on mounting pucks.
    Smooth samples can be attached to the chuck using chuck vacuum.

    Wet samples: Optional fluid cell with / without temperature control in liquids. Useful range is 4- 50 ºC in water

    Optical microscope: 10X Nikon objective, 450X magnification range with 14-inch image. 12.7 mm travel two-axis stage.

    Heater / Cooler: Provides samples heating and temperature control from -35 ºC to 100 ºC for samples (0.6x0.6x0.5 mm) in air or other inert gases.

    SSRM: Image carrier concentrations 1015 – 1020 carries/cm3. Resistance is measured using a logarithmic current amplifier with range 10pA -0.1 mA.

    Extended TUNA: Range: 150 fA to 2000 nA; Noise: 150 fA RMS in pA range, 10 pA RMS in nA range. A bias of mV to 12 V can be applied.

    Thermal control measurements: MultiMode heater/cooler line provides increased thermal-control convenience to life sciences and polymers research.
