Abstract
An optical element having a light carrying medium through which light can propagate by total internal reflection. The light carrying medium has at least one surface. A layer is positioned adjacent the surface and is of a porous first material of sufficient porosity and with pores which are vacant or contain a second material having an index of refraction lower than that of the light carrying medium, such that the layer reduces total internal reflection in the light carrying medium less than would be reduced using a non-porous layer of the same dimensions of only the first material. A light integrator and scanner using such integrator are also provided.
