Development of a Versatile Near Field Optical Imaging System Derek Nowak, Portland State University Portland, Oregon Co-Authors: Justin Hiester, Deepak Vedhachalam, Zechariah K. Dzegede, Erik J. Sánchez The ability to detect optical information from optically active systems with resolutions below the diffraction limit of traditional light microscopes is of great interest of biologist and material scientists. Using the technique of Tip Enhanced Near-field Optical Microscopy, or (TENOM) (Sánchez, PRL. 1999), fluorescence imaging with ~20 nm resolution has shown to be possible. TENOM demonstrates these optical resolutions with simultaneous topographical information as well as the ability to detect with both electronic state and vibrational bond (Raman) information for single-molecule level identification. TENOM utilizes an Atomic Force Microscopy (AFM) scanning method where the imaging probe has been modified to create a localized field enhancement. The microscopes ability to image in solution is an additional feature. Unfortunately, TENOM has not seen common day use as a research tool, due primary to the level of understanding needed by the user to create suitable probes and correctly operate the microscope. Our goal has been to develop a TENOM based microscope controlled by a single low cost computer, simple control circuits using FPGA data acquisition, and simplified optical system allowing for imaging with photons from almost any visible chromophore without changing …
In part two of our NeoFox tutorials, we show you how to perform a two-point calibration. In this example we will be using Nitrogen as the Zero percent Oxygen standard, and room air as our second standard at 20.9% Oxygen. If you have not setup your NeoFox software, please view the first video in the series for help doing so. For more information, visit www.oceanoptics.com Video Rating: 5 / 5

World’s first and only PCI-SIG certified PCIe Over Fiber Optic expansion system In production from 2007. In certain cases this system can be used as an Alternative to Intel Light-Peak technology to schedule for release in 2011. www.adnaco.com Video Rating: 5 / 5
The Adnaco S3 System allows to extend standard hi-speed USB interface to a distance of up to 250 meters (approximately 1000 feet) from the host PC. This is accomplished without any kind of special software other than normal OS software already installed on the computer
