abstract

A new type of Raman spectroscopy hyperspectral imager based on Bragg tunable filter has been developed by University of Montreal and Photon etc. The technology of Bragg tunable filter significantly reduces the acquisition time by selecting a single wavelength in a full camera field and scanning the wavelength with a high efficiency. The transmission is continuously tunable over 400 nm range with a spectral resolution of 0.2 nm. We here present the principle of this novel Raman imaging system as well as hyperspectral images of a Si/Ti structured wafer and carbon nanotubes taken with a spectral resolution of 0.2 nm on the whole field of view of the microscope. © (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
