Rod integrator lenses are used to utilize the end face as the light entrance and exit surface, with the purpose of homogenizing uneven energy distribution. The light incident on the rod integrator undergoes total internal reflection repeatedly, resulting in a uniform illumination distribution. By transferring the image of this exit surface with a relay lens, a uniform energy distribution can be obtained at the final surface.
