NSOM (SNOM) Overview

The limits of far field imaging

In the early 1870s, Ernst Abbe formulated a rigorous criterion for being able to resolve two objects in a light microscope: 

d > λ / (2sinθ) 

where d = the distance between the two objects, λ = the wavelength of the incident light, and 2θ = the angle through which the light is collected.

FEI Company, a leading instrumentation company providing electron microscope systems for applications across many industries, has announced that it has entered into an agreement to collaborate with Nanonics Imaging Ltd. to explore the feasibility of adding an atomic force microscope (AFM) to an FEI DualBeam™ focused ion beam (FIB)/scanning electron microscope (SEM) system.
 
Nanonics' AFM is used for imaging, measuring and manipulating matter at the nanoscale. It uses a mechanical probe to measure the surface topography of a sample. The DualBeam is a FIB/SEM system that provides three dimensional (3D) imaging and analysis down to the nanoscale. The DualBeam uses an SEM to image FIB-milled cross sections, which reveal subsurface features.

Nanonics' MultiView 4000

About Nanonics 
Nanonics Imaging Ltd. is the market leader of combined near-field optical microscopes (commonly referred to as either NSOM or SNOM systems) and atomic force microscopes (AFM). Incorporated in 1997, Nanonics is the longest established and most experienced supplier of such systems in the market, whose products have won several awards. These awards have recognized innovations and pioneering developments in multiprobe atomic force microscopy and transparently integrated AFM Raman microspectroscopy. Nanonics platforms with their associated probe technologies have circumvented barriers that have prevented AFM from effective integration into electron optical and similar upright microscope geometries.

Haegel heading to the Hebrew University in Jerusalem to work with Professor Aaron Lewis

 

Nanonics warmly congratulates Distinguished Professor Dr. Nancy Haegel of the Physics Department at the Naval Postgraduate School (NPS) in Monterey, CA for winning a 2012 Fulbright scholar award for her research and lecturing in near-field scanning optical microscopy.  Haegel’s work will take her to Hebrew University in Israel, where she will have the opportunity to work with and learn from Professor Aaron Lewis of the Department of Applied Physics, a world-renowned expert and pioneer in near-field imaging techniques. 

Professor Haegel developed a novel system for imaging carrier transport within semiconductor nanostructures using the Nanonics MultiView 2000 AFM inside a scanning electron microscope (SEM).

 

It is a great honor to be selected by the Foreign Scholarship Board for a Fulbright award to Israel,” said Haegel. “I am very excited about the opportunity to participate in cutting-edge research at Hebrew University and also to help build the international relationships and collaborations that are central to the Fulbright Program. To do the best job in teaching and research, we always need to be learning new things and seeing the world from different perspectives. This is a great opportunity to do exactly that.”

 

Among Haegel’s many previous honors are a David and Lucile Packard Fellowship in Science and Engineering (1988), a Humboldt Fellowship at the Max Planck Institute for Extraterrestrial Physics (2000), the American Physical Society Prize for Research at an Undergraduate Institution (2004), the Schieffelin and Griffin Awards for Teaching Excellence at NPS (2008, 2010). Professor Haegel is a member of the Board of Trustees of the University of Notre Dame and recently completed a three-year term on the American Physical Society Committee on the Status of Women in Physics.

 

The Fulbright Scholar Program is administered by the Council for International Exchange of Scholars, and sponsored by the United States Department of State, Bureau of Educational and Cultural Affairs. The program sends 800 U.S. faculty and professionals abroad each year.

AFM courses offered online for the first time by Purdue University professors this fall will cover static and dynamic methods and provide instruction on a widely used AFM simulation tool, VEDA. Like the massive open online classes that have been making headlines, the new AF courses will be delivered to broad audiences, but nanoHUB-U\'s initiative is unique -- providing instruction and cloud services for performing computationally intensive simulation from a Web browser
