Abstract: An optical substrate having a structured prismatic surface and an opposing structured lenticular surface. The structured lenticular surface includes shallow-curved lens structures. Adjacent shallow-curved lens structure may be continuous or contiguous, or separated by a constant or variable spacing. The lens structure may have a longitudinal structure with a uniform or varying cross section. The lenticular lenses may have a laterally meandering structure. Sections of adjacent straight or meandering lenticular lenses may intersect or partially or completely overlap each other. The lenticular lenses may be in the form of discontinuous lenticular segments. The lenticular segments may have regular, symmetrical shapes, or irregular, asymmetrical shapes, which may be intersecting or overlapping, and may be textured. The lens structure may be provided with isolated ripples, in the form of a single knot, or a series of knots.
