A multispectral imaging apparatus includes a processor and a plurality of sets of light-emitting diodes (LEDs) in communication with the processor. One or more first sets of LEDs has a wavelength in a visible range, and one or more second sets of LEDs has a wavelength in a short wavelength infrared range. The apparatus includes a truncated source cone through which light from the plurality of sets of LEDs is directed onto a surface and through which light reflected off of the surface is received. The apparatus also includes a visible light camera configured to capture a first image of the surface based on reflected light that originates from the one or more first sets of LEDS. The apparatus further includes an infrared light camera and configured to capture a second image of the surface based on reflected light that originates from the one or more second sets of LEDs.
