ABSTRACT:
An LED spectrophtometer device for determining an aspect of the color of an object may include: a visible spectrophotometer comprising a plurality of light emitting diodes that emit light in the visible spectrum onto the object; at least one detector for detecting said light after being directed onto the object and for generating an output; and a UV light emitting diode assembly that emits light in the near ultraviolet spectrum and communicates with at least one detector for generating an output. The device may further include a processor that combines the outputs of the at least one detector of the visible spectrophotometer and the at least one detector in communication with the UV light emitting diode assembly.
