Abstract
An optical element is provided having an asymmetric body, a light source, and a front face tilted at an oblique angle with respect to a target surface to provide illumination that is at least substantially uniform along the target surface's height. One or more optical elements may be in an apparatus, and multiple apparatuses may be disposed in front of one edge of a target surface to provide thereto at least substantially uniform oblique illumination. When the light source is an LED that is spectrally non-uniform at increasing angles away from its optical axis, the optical elements having such LEDs provide illumination that is spectrally non-uniform along a portion of the target surface, and additional optical elements with LED light sources are provided having a spectrum in one or more spectral ranges that compensates for such spectral non-uniformity to correct spectral non-uniformity along such portion of the target surface.
