New design of the excitation light source that can stably generate light with center wavelengths of 450nm, 530nm,
632.8nm and white light for auto-fluorescence(AF) and photodynamic diagnosis(PDD) of cancer in clinics in a single
system is presented in this study. The light source consists of Xenon Lamp (300W), light guide module including
motorize filter wheel equipped with optical filters with corresponding to wavelength bands, servo motor, motorize iris, a
cooling system, power supply and optical transmission part for the output light. The transmission part of the light source
was developed to collimate the light with desired wavelength into input of fiber optic. Output powers are obtained
average 99.91 mW for 450±40 nm, 111.01 mW for 530±10nm, and 78.50 mW for 632.8±10nm.
