An apparatus for directing uniform intensity light onto a surface where the light is provided at an acute angle with respect to the surface including a light source that generates initial light rays that are essentially perpendicular to the surface and a guidance member positioned between the source and the surface which receives the initial rays and redirects the rays such that redirected rays are parallel and form acute angles with respect to the surface, the source and guidance member juxtaposed with respect to the surface so that the redirected rays subtend the surface.
