ezAFM+
The ezAFM+ is a robust, compact Atomic Force Microscopy system
which capable of providing high resolution images. The ezAFM+ is versatile and
has numerous applications in materials science, biology, chemistry, physics,
industrial and aerospace research. While Ease-of-use and pricing make it ideal
for high school and university teaching laboratories, the capabilities and
performance of the ezAFM+ have attracted more advanced users from some of the
more important international institutes, universities and industrial
laboratories as well.
The ezAFM+ operates in Dynamic Mode, Contact Mode, Lateral
Force Microscopy, Magnetic Force Microscopy and Liquid Mode. User may
purchase a system with one standard scan mode or optionally up to a maximum of
5 scan modes. These additional modes can be purchased later, if
needed. When purchased, the ezAFM+ package typically includes a
controller, scan head, vibration isolation unit, laptop, user tool kit and a
cantilever starter pack. Users may install the system by following simple
plug and play instructions as described in the manual. Software
installation and system tests are made from remote by our ezAFM+-Application
Scientists. Installation is followed by some training in making simple
measurements.
ezAFM+ Design
ROBUST & FLEXIBLE: The design of the ezAFM+ allows users to replace/exchange the
scan heads easily, safely and frequently. Each system can have scan heads
for different scan size, Z range or air/liquid mediums.
EASE-OF-USE: In most commercial AFMs, replacement of the cantilever can be
a daunting task for the user as it involves realigning the laser and photodiode
after each cantilever exchange. Nanomagnetics Instruments Limited
has made this routine simple and easy by utilising the fact that there is a vast
range of commercially available cantilevers which have alignment grooves on the
back side of the chip. Specially designed ‘alignment chips’ are
incorporated in the design of our scanner heads, in such manner, that when the
cantilevers are mounted, they will locate in the exactly the same position with
respect to the laser beam thereby eliminating the need realign the laser or the
photodiode.
COMPACT & PORTABLE: With a footprint of only 70cm x 30cm (including the laptop),
the ezAFM+ requires little operating space. It is light and comes packed
in a durable pelican case for easy transportation or storage. The
microscope can also be placed in a glovebox in situations where enhanced
environmental control is required.
VERSATILE: NanoMagnetics Instruments offers two different scan heads for
the ezAFM+ for operation in ambient conditions. The ezAFM+120 scan head has a
maximum scan area up to 120x120x40µm and is best suited for samples with rough surfaces and
it provides a 0.2 nm resolution in Z. The 40um Z range is much larger
than that offered by most commercial systems allowing for imaging of a greater
range of corrugated sample like textiles, fibres and paper pulp. The ezAFM+40
scan head, on the other hand, has a maximum scan area is 40x40x4µm and with a 0.02nm
resolution (in Z), which will allow you to scan single layer graphene
surfaces. Additionally, although the typical sample size for the ezAFM+
is 10x10x5 mm, it can be easily
reconfigured to images very large surfaces.
A separate Aqua Head is available for imaging in liquid
environment. Both air/liquid heads may also be integrated with an
Inverted Light Microscope (ezAFM+-ILM) of your choice.
XY Manual Stage
Sample positioning is achieved using a flexure stage with movement controlled through manual screws with movement range of 2x2mm with 10µm resolution. Fine position of sample is adjusted by moving manuel stage.
XY Motorized Stage
Remotable and automatic sample movement in X and Y directions can be achieved using motorize movement stage unit with software control with 19×19 mm movement range.
Signal Access Module (SAM)
Signal Access Module provides input and output signal access between electronic and microscope. The Signal Access Module has 2 spare analog input channels with and 7 output channels. RMS and phase signal for cantilever tuning, cantilever excitation signal and cantilever movement in X,Y and Z directions can be obtained from output channels.
