1. A method of identifying a multi-composition calculi target during an endoscopic procedure, the method comprising:
changing an illumination mode of an endoscopic illumination source in an endoscope from a first mode to a second mode, the first mode having a first amount of illumination and the second mode having a second amount of illumination lower than the first amount;
causing a non-endoscopic illumination source to emit a diagnostic beam proximate a distal end of the endoscope and directed at a single target comprising multiple calculi compositions of respective different materials when the illumination mode of the endoscopic illumination source in the endoscope is changed from the first mode to the second mode;
receiving reflected light of the diagnostic beam from the single target, the reflected light being enhanced as a result of the change in the illumination mode; and
determining a composition of the single target, including determining a first composition of a first material in a first calculus portion of the single target and a second composition of a second material in a second calculus portion of the single target different than the first composition, based on the diagnostic beam incident on the single target and the reflected light of the diagnostic beam.
