Abstract: Systems, apparatus, and methods for double-sided imprinting are provided. An example system includes first rollers for moving a first web including a first template having a first imprinting feature, second rollers for moving a second web including a second template having a second imprinting feature, dispensers for dispensing resist, a locating system for locating reference marks on the first and second webs for aligning the first and second templates, a light source for curing the resist, such that a cured first resist has a first imprinted feature corresponding to the first imprinting feature on one side of the substrate and a cured second resist has a second imprinted feature corresponding to the second imprinting feature on the other side of the substrate, and a moving system for feeding in the substrate between the first and second templates and unloading the double-imprinted substrate from the first and second webs.

Abstract: In an example method of forming an optical film for an eyepiece, a curable material is dispensed into a space between a first and a second mold surface. A position of the first mold surface relative to the second mold surface is measured using a plurality of sensors. Each sensor measures a respective relative distance along a respective measurement axis between a respective point on a planar portion of the first mold surface and a respective point on a planar portion of the second mold surface. The measurement axes are parallel to each other, and the points define corresponding triangles on the first and second mold surfaces, respectively. The position of the first mold surface is adjusted relative to the second mold surface based on the measured position, and the curable material is cured to form the optical film.
