Latest Patents

One of Gallagher's latest patents is titled "Two-stage optical object molding using pre-final form." This invention involves creating a lens, such as one used in a wafer-level camera, by forming a polymeric material with at least one master to create a pre-final lens. The pre-final lens constitutes a majority of the final lens volume and is allowed to harden, during which it may sag or shrink. An aliquot of polymeric material is then added to form a first surface layer that corrects the shape between the pre-final lens and the desired final lens shape. Additionally, the lens can be formed on a substrate, and a second aliquot of polymeric material can create a second surface layer on the opposite side of the lens.

Another significant patent is "Imaging system including distributed phase modification and associated methods." This invention describes an imaging system designed to capture image data across a range of field points, both on- and off-axis. It includes an image sensor and two optical elements that work together to modify the phase of light transmitted through them, ensuring that the point-spread functions are uniform across the field.
