1. A light intensity converter comprising:

  • a body including a first curved surface extending transversely of a center axis, a second curved surface extending transversely of said center axis, and an outer peripheral surface extending between said first curved surface and said second curved surface; and

    wherein said body is constructed such that a light having first light intensity distribution is made incident to said body at said first curved surface, the incident light diverges in a first area in said body and converges in a second area in said body, by refraction, when the light enters said body from said first curved surface, and the light emerges from said body at said second curved surface, the emerging light having a second light intensity distribution different from said first light intensity distribution, wherein said first light intensity distribution is a Gaussian distribution, and said second light intensity distribution is a uniform distribution.
