Advanced, fully-featured SPM
The MultiView 2000TM series is an advanced single probe scanning probe microscope enabling a variety of modes of AFM/SPM/NSOM imaging. Nanonics has designed The MultiView 2000TM for excellence in scanning probe microscopy while allowing for near-field and far-field optical NSOM/AFM Raman/TERS imaging without perturbation. The Multiview 2000TM is the only commercially available instrument that offers both tip and sample scanning. This versatility is important for different operation modes where the user can now choose whether the sample or tip is static. The Multiview 2000TM further offers the most stable feedback mechanism available in the form of normal force feedback with tuning fork actuation. This feedback mechanism offers the most stability, as well as laser-free operation for the most sensitive experiments.

Dual sample and tip scanning stages in the same head for ultimate flexibility is coupled with an optically friendly Nanonics 3D Flat ScanTM stage providing up to 85μ in X, Y and Z or 170μ in X, Y and Z using combined scanners. This scanner is also suitable for large samples with unconventional geometries. Closed loop is an option for positioning accuracy of 20nm.
Additionally, a revolutionary, alignment-free feedback system provides the most sensitive tip-sample stability. Normal force feedback with tuning fork actuation provides no alignment, laser-free operation for improved optical signal to noise ratio, and ultra-sensitive force spectroscopy perfect for force and adhesion measurements.

The large, 85μ X, Y and Z-range of the Nanonics 3D FlatscanTM makes it ideal for optical sectioning in confocal imaging. Used in this way, the MultiView 2000TM integrates conventional far-field imaging, confocal microscopy, AFM, and near-field optics in a single system
Nanonics provides a wide variety of probes that are compatible with the MultiView 2000TM, including: transparent, cantilevered probes, thermal probes, electrical probes (electrochemical probes, coax probes, glass insulated wire probes) and all third party silicon probes
The unique geometry of the MultiView 2000TM head and cantilever probes leaves the optical axis free both above and below the sample for integration with upright, inverted, and dual optical microscope configurations.
Irregular sample sizes, whether odd in shape or large in size, can be easily placed on the sample stage.
The sample can even be suspended from the unobstructed flat scanning sample stage in order to examine the edges of the sample.

True Collection Mode
The MultiView 2000 offers both tip scanning and a sample scanning stage. A sample scanning stage enables easy and rapid alignment of the sample relative to the illumination source and ensures that the microscope optics are independent of the AFM scanner. A tip scanning stage means that the tip can be scanned while the illumination point (either from above or below) is held static.
For an explanation of all modes of NSOM, please see the tutorial on NSOM modes. This instrument design is ideal for true collection mode NSOM, where the light illuminates the sample, and then collected through the NSOM probe by a detector (see schematic on right).
True reflection mode NSOM
In true reflection mode, light is introduced via the NSOM probe, and then collected by a detector above the probe as shown in the schematic below. The design of the MultiView series take advantage of transparent probes and separates the excitation and collection paths so that they don't affect each other. Other designs that take advantage of straight probes or apertured Si probes are significantly more challenging for reflection mode NSOM experiments.
-More on different modes of NSOM can be found on the NSOM tutorial page.
Nanonics is the global pioneer in glass probe manufacturing and has developed a whole suite of probes for all your NSOM applications featuring:
-Glass cantilevered normal force probes. These types of probes operate as standard robust AFM probes for easy, high-quality imaging of all samples. Additionally, the optical transparency of these probes provides unobstructed optical view from above and below
-Fiber probes with metallic nanoparticles in tip
-Straight probes also available for shear force feedback measurements
This enables total flexibility in your NSOM setup, as the MultiView 2000 can be integrated with any optical microscope. Additionally, total optical access to sample and probe position from above is possible since the cantilever probe/scanner assembly does not obscure access

The Multiview 2000 is equipped with a laser-free feedback method called normal force tuning fork feedback. For example, many SPM laser-based feedback systems employ red lasers, which would then interfere with the Raman emission in the red from the sample. The Multiview 2000 gets rid of all problems associated with optical interference in your Raman experiments.
With a Multiview 2000, no modification of the Raman path is necessary to accomodate the SPM tip and head. This design results in a natural and straightforward Raman path for integration without the need for tilting or bending the Raman path to accomodate the SPM. Furthermore, transparent optical probes provide a completely transparent optical system. Both reflection Raman and transmission Raman are standard on the MV 2000
Quick and easy TERS hotspot detection
Combined tip and sample scanning stage provides accurate positioning of the probe at the ideal location with respect to the focused laser spot. Tip can be positioned within the center of the Raman hotspot for optical Raman signal detection
Sample can be scanned without losing the Raman hotspot position
All modes of TERS including STM and AFM-TERS with easy interchangeability. Thus the same probe (either conducting or with a conductive coating for STM-based feedback) can be operated as an AFM probe using tuning fork based feedback, and then it can be switched to tunneling based feedback for TERS operation

The MV 2000 combines the ability to scan large z ranges (upto 170um), suitable for Raman imaging of most biological species. In addition, the MV 2000 can image biological species in situ in aqueous environments with the ability to work with a water immersion objective; the advantages of working with a water immersion objective are described in the tutorial. In addition, the tuning fork feedback provides the ultimate force sensitivity to conduct AFM-based measurements on soft samples.
Raman imaging in fluids can be combined with other functionalities such as scanning electrochemical microscopy (SECM). A description of combined Raman-SECM with an application of in situ monitoring Cu etching can be viewed here or downloaded by clicking here.
The MV 2000 provides autofocusing onto the sample at every pixel point. Thus for rough samples, tilted samples, or samples with unusual Z variation, the Multiview 2000 provides the best Raman resolution as it makes sure to have the sample in focus at every point a Raman spectrum is collected
The MV 2000 can be combined with either an upright, inverted, or a dual microscope (combined upright and inverted) where the same SPM head is used for either microscope configuration.
