Karrai and M. Haines US Patent Number 5,641,896. The work of Karrai and coworkers was patented for straight near-field optical/AFM elements with highly restricted geometries of tip attachment and movement. Nanonics extends this technology The Nanonics Proprietary in two directions: First, the use of proprietary, simple, mounting techniques that Tip Mount maintain resonance frequencies and Q factors and resolve problems with tuning Viewed from fork feedback, as noted previously [D. N. Davydov, K. B. Shelimov, T. L. Haslett the Tip Side and M. Moskovits, Appl. Phys. Lett. 75, 1796 (1999)]; and second, applying these mounting techniques to cantilevered near-field optical and AFM elements to provide performance at the limits attainable with scanned probe techniques. Tip Scanning Waveguide characterization highlights the utility of having tip and sample scanning available in a single system. The distribution of light emanating from the edge of a waveguide can be best imaged by collection mode tip scanning. In this case, the light is injected into the bottom of the waveguide through an inverted microscope objective or an input fiber. The geometry of the light source and waveguide must be kept stationary throughout the measurement, and sample scanning would disturb the injection of light into the waveguide. Thus, tip scanning collection mode is preferred in this case and in similar experiments. Using an on-line optical microscope allows simultaneous viewing of the edge of a hanging planar waveguide and the NSOM/AFM cantilevered tip as it is positioned to inject light into the waveguide (top left image). The waveguide is hung on the bottom plate of the sample scanner while the tip is mounted on the top plate, the tip scanner (bottom left image).
Sample ScanningMany experiments are performed best using sample scanning.For example, one might want to monitor, with ultra high resolution,index of refraction variations along the edge of the waveguide togetherwith AFM topography. Light emitted from the NSOM tip and reflectedoff the edge of a waveguide is collected by a high numerical aperture(NA) microscope objective. In such an optical measurement, tipscanning relative to a high NA objective destroys the axial symmetryof the optical system and can result in image artifacts. Tip artifactshave to be avoided to reach the ultimate in these super resolutionreflection measurements of index of refraction that can monitoralterations of <1/1000.The MultiView 2000™ Series also includes the LT Low Temperaturesystems that Nanonics provides. Soft Sample Imaging of a Fibril of Associated Protein MoleculesThe MultiView 2000™ Series builds on the standards of modularity,flexibility, and full system performance that were established by theMultiView 1000™.

At Nanonics Imaging, both the optical microscope and thescanned probe imaging system are given equal importance. No other manufacturerof scanned probe or optical microscopes can provide for such effective solutionsin both these growing areas of imaging. The result is the ultimate degree ofintegration in imaging methodologies.
