November 1, 2013 – Acton, Massachusetts - Princeton Instruments is pleased to announce that the award-winning IsoPlane spectrograph has been used in recent, groundbreaking research in single-molecule tip-enhanced Raman spectroscopy by the Van Duyne group at Northwestern University.
Sonntag et al., “The Origin of Relative Intensity Fluctuations in Single-Molecule Tip-Enhanced Raman Spectroscopy,” has recently been accepted for publication by The Journal of the American Chemical Society (DOI: 10.1021/ja408758j). The researchers combined the techniques of single molecule tip-enhanced Raman spectroscopy (SMTERS) and scanning tunneling microscopy (STM) to obtain unprecedented sensitivity and spatial resolution in Raman spectra of single rhodamine 6G molecules. The results constitute a significant advance in the understanding of excited-state dynamics in adsorbate-substrate interactions. The experimental setup included the PIXIS 400B CCD camera and IsoPlane SCT-320 spectrograph from Princeton Instruments.
About IsoPlane:
The IsoPlane® (patent pending) spectrograph features a revolutionary new optical design that eliminates field astigmatism and greatly reduces other aberrations inherent in the design of the Czerny-Turner spectrograph. It produces images with much higher spatial resolution across the focal plane than any mirror-based spectrograph on the market. The IsoPlane reduces instrumental line width limitations, significantly increasing the effective signal-to-noise ratio (SNR) of single-molecule Raman spectra. Thanks to its superior imaging ability, the IsoPlane also eliminates crosstalk in multi-channel spectroscopy, providing an 8X increase over comparable instruments in the number of fiber spectra that can be spatially resolved over the height of a CCD array. Together with Princeton Instruments’ industry-leading CCD, EMCCD, ICCD, and InGaAs cameras, as well as highly reflective mirror coatings from Acton Optics, the IsoPlane offers the best available performance in optical spectroscopy.
