<p>Screens for use with image-forming illumination (53, 54) are provided, as well as methods for producing such screens. The screens include an array of lenses (51), a substrate, and a layer of light-absorbing material (5) in which apertures are formed using aperture-forming illumination (52) which passes through the lenses (51). The optical properties of the lenses (51) and the thickness of the substrate are selected so as to maximize the light-blocking area of the layer of light-absorbing material (55) while allowing long-wavelength image-forming illumination (54) to pass through the apertures substantially unimpeded. The array of lenses can be an array of randomized, anamorphic microlenses.</p> |
