Abstract: Methods and systems for Raman spectroscopy and context imaging are disclosed. One or two lasers can be used to excite Raman scattering in a sample, while a plurality of LEDs can illuminate the sample at a different wavelength. The LED light is collected by a lenslet array in order to enable a high depth of field. Focusing of the image can be carried out at specific points of the image by processing the light collected by the lenslet array.
