Center for Planetary Exploration at Stony Brook University WITec Alpha300R Raman Imaging Spectrometer Spectrometer Raman Spectrometer The WITec Alpha300R Raman Imaging Spectrometer is located at the Center for Planetary Exploration at Stony Brook University. It features 2 laser excitation sources (532 nm and 785 nm), an advanced confocal microscope, 2 high throughput spectrometers, and software capable of powerful multivariate analysis. It acquires spectra from 3500-100 Δcm-1 and is equipped with multiple objective lenses, allowing for spatial resolutions between several microns and 350 nm/pixel.
