ABSTRACT:
The disclosure relates to method and apparatus for obtaining a multimodal hyperspectral image of a sample for widefield spectral analysis. An apparatus according to one embodiment may include a plurality of optical lenses configured to interchangeably receive photons and focus the photons; a plurality of tunable filters positioned in a filter housing, each tunable filter selectively receiving the focused dispersed photons from one of the plurality of optical lenses, each tunable filter providing wavelength-selective filtered photons; a first optical camera and a second optical cameras for selectively receiving the wavelength-selective filtered photons from each of the plurality of tunable filters and combining said filtered photons to form a hyperspectral spatially accurate, wavelength-resolved image of the sample.
