The present invention provides a light source apparatus and method for integrating diffused light with high efficiency using a collimating including an axicon lens, collimating it, tuning the wavelength of desired light, and passing it. A tunable wavelength light source apparatus of the present invention according to one embodiment comprises a diffuse light source for irradiating diffused light, a collimating module for collimating the light irradiated from the diffuse light source, wherein the collimating module comprises an axicon lens, an angularly tunable bandpass filter module for passing the light that has passed through the collimating module to select a specific wavelength of the light, and a mixing module for correcting a spatial error of a wavelength specified according to an angle of incidence of the light passing through the angularly tunable bandpass filter module
