Abstract: A liquid lens that includes: a lens body comprising a first window, a second window, and a cavity disposed between the first window and the second window; and a first liquid and a second liquid within the cavity of the lens body, the first liquid and the second liquid substantially immiscible with each other and having different refractive indices such that an interface between the first liquid and second liquid to form a lens. The sidewall of the cavity has an average surface roughness (Ra) of less than or equal to 200 nanometers (nm). The cavity is disposed within a plate. Further, each of the windows and the plate comprises a glass, glass-ceramic or ceramic composition. In addition, a linearity of a first bottom portion of the sidewall in proximity to the base of the plate can be from 0 μm±5 μm.

Abstract: A method of separating a substrate includes directing a laser beam into the substrate such that a focal line is formed with at least a portion of the laser beam focal line within a bulk of the substrate at an oblique angle with respect to a laser-incident surface of the substrate. The laser beam focal line is formed by a pulsed laser beam that is disposed along a beam propagation direction. The method further includes pulsing the pulsed laser beam from a first edge of the substrate to a second edge of the substrate in a single pass. The laser beam focal line generates an induced multi-photon absorption within the substrate that produces a damage track within the bulk of the substrate along the laser beam focal line, and the damage track is at an oblique angle relative to the laser-incident surface of the substrate.

Abstract: A method for processing a transparent workpiece that includes directing a laser beam the transparent workpiece. The laser beam incident to the impingement surface has an oblong angular spectrum and portion of the laser beam directed into the transparent workpiece is a laser beam focal line and generates an induced absorption to produce a defect within the transparent workpiece. The laser beam focal line includes a wavelength λ, a spot size wo, a Rayleigh range ZR that is greater than
