Patent number: 9690014Abstract: A gradient-index lens for focusing incident electromagnetic radiation comprises at least first and second substrates. Each of the substrates has a plurality of trenches or holes formed therein. The first substrate is stacked on the second substrate such that trenches or holes in the first substrate are substantially aligned with corresponding trenches or holes in the second substrate to form combined trenches or holes. Each of the combined trenches or holes has a width or diameter that is less than a wavelength of the electromagnetic radiation, and the spacing between adjacent ones of the combined trenches or holes is less than the wavelength of the electromagnetic radiation. The size and spacing of the combined trenches or holes in the stacked substrates are sufficient to produce an effective refractive index profile of the lens element that is graded. A method for producing the lens is also provided.Type: GrantFiled: December 10, 2015Date of Patent: June 27, 2017Assignee: INVIS TECHNOLOGIES CORPORATIONInventors: Gregory J. Kintz, Philip J.

Publication number: 20170168199Abstract: An imaging device comprises a focal plane array (FPA) having a plurality of singulated unit cells arranged on a carrier substrate. Each of the unit cells comprises a sub-array of pixels in the focal plane array. At least one of the unit cells has a different number or type of pixels than does another one of the unit cells arranged on the carrier substrate to enable multi-spectral imaging. The device also includes at least one lens positioned to direct incident electromagnetic radiation to the unit cells. A modular method for producing the FPA and lenses of a camera core uses wafer-level packaging and optics. Lenses and sub-arrays of pixels are each fabricated on densely packed, batch-fabricated wafers, and subsequently singulated and assembled into arrays on respective low cost carrier substrates. The carrier substrates are bonded together at the substrate level to form a series of camera cores, and the stacked substrates are singulated to form individual camera cores.Type: ApplicationFiled: February 24, 2017Publication date: June 15, 2017Applicant: INVIS Technologies CorporationInventors: Srinivasan K.
