FALCON II™ Wide-Field Raman Chemical Imaging System
Q: What is the spatial resolution of FALCON II?
A: Diffraction-limited spatial resolution is achievable (~350 nm) for the Raman Chemical Imaging channel.
Q: What is the spectral resolution of FALCON II?
A: The achievable spectral resolution of the FALCON II dispersive channel is 3.3 cm-1. The achievable spectral resolution of the FALCON II Raman imaging channel is ~9 cm-1 (@ 532 nm). The ability to resolve subtle spectral shifts is on the order of <0.1 cm-1.
Q: What laser options does the FALCON II support?
A: Our FALCON II system is equipped with a Nd:YAG laser for 532 nm excitation.
Q: How big of an area are you able to see on the sample with the FALCON II?
A: When performing Raman Chemical Imaging, the area illuminated by the laser beam limits how much of the sample can be characterized in a single measurement. The diameter of the laser spot ranges from approximately 25 microns (100x objective) to 2 millimeters (1.25x objective). Analysis of larger areas can be easily obtained by simply collecting a montage of adjacent fields-of-view on the sample.
Q: What is the footprint of the FALCON II?
A: 36” x 25” x 75” (0.91m x 0.64m x 1.9m)
Q: How long does it take to acquire an image?
A: The length of time to generate an image depends on many variables (i.e., relative wavenumber range being scanned, spectral step size, Raman scattering efficiency of sample, fluorescence properties of sample, etc.). Generally, single field-of-view images may be acquired in time periods ranging from several seconds to a few minutes.
