ABSTRACT:
A projection system includes a modulator and a field lens. The modulator is to modulate light in accordance with image data. The field lens is to at least partially collect the light modulated by the modulator. The field lens has a number of elements. Each element has a wedged shape different than wedged shapes of neighboring elements.
