摘要： A pulsed laser beam is used to create apertures in a layer on a back side of a substrate that includes a microlens array on a front side thereof. The pulsed laser beam is focused in a vacuum spatial filter. A profile of the pulsed laser beam that emerges from the vacuum spatial filter is converted to a top hat profile. The laser beam having the top hat profile is diffused. Finally, the pulsed laser beam having the top half profile that has been diffused is impinged through the microlens array on the front side of the substrate and onto the layer on the back side of the substrate. Related apparatus for creating the apertures and microlens array products are also described.

摘要： Optical microstructures, such as microlenses, are fabricated by rotating a cylindrical platform that includes a radiation sensitive layer thereon, about its axis, while simultaneously axially rastering a laser beam across at least a portion of the radiation sensitive layer. The cylindrical platform is also simultaneously translated axially while it is being rotated. The amplitude of the laser beam is continuously varied while rastering. The optical microstructures that are imaged in the radiation sensitive layer can be developed to provide a master for replicating a microlenses.

摘要： Light transmissive structures include a light transmissive substrate that includes optical microstructures. The optical microstructures have a geometric feature that is configured to reduce glare in light transmitted through the light transmissive structure. Moreover, the plurality of optical microstructures also have a geometric feature that is configured to vary randomly and/or pseudorandomly across the light transmissive substrate so as to diffuse light transmitted through the light transmissive structure. Related fabrication methods are also described.

摘要： Microstructures are fabricated by imaging a microstructure master blank that includes a radiation sensitive layer sandwiched between a pair of outer layers, on an imaging platform, to define the microstructures in the radiation sensitive layer. At least one of the outer layers is then removed. The microstructures that were defined in the radiation sensitive layer are developed. The radiation sensitive layer sandwiched between the pair of outer layers may be fabricated as webs, to provide microstructure master blanks.

摘要： The novel optical recording medium, as in the prior art, has a transparent substrate bearing two recording layers, each addressable from only one side of the medium, but unlike prior 2-sided media, the two recording layers are on the same face of the substrate. When the novel medium is addressed from one side of the substrate, a thin-film barrier, such as an opaque metal, between the two recording layers prevents the more distant recording layer from responding to that energy. Preferably a tough, transparent cover layer is sealed to the substrate to protect the two recording layers.
