The utility model relates to a quality detection device for selective spectrum highlight medical equipment, which belongs to the technical field of measurement and test of selective spectrum highlight medicine. The quality detection device comprises a selective spectrum highlight generator, a light attenuation system, a concentrating system, a light splitting system, a photoelectric detector and a computer, wherein the selective spectrum highlight generator is fixed on a detection platform; the computer controls the bidirectional movement of the detection platform through a step motor; and the highlight generated by the selective spectrum highlight generator passes through the light attenuation system, the concentrating system and the light splitting system in turn and is received by the photoelectric detector and converted into electrical signals, and the electrical signals are sent to the computer to perform data detection. The quality detection device can detect a curve graph of distribution and energy of spectrum of each point so as to acquire a three-dimensional curve graph of distribution and energy of spectrum of the whole working face, radically ensure the consistency of instrument quality and provide physical-layer technical base aiming at the optimal clinical effects of different individuals.
