    Abstract: In a method for imaging a container holding a sample, the container is illuminated with a laser sheet of a first color, and one or more images of the container are capturing by a first imager configured to filter out colors other than the first color. Simultaneously with illuminating the container with the laser sheet of the first color, the container is illuminated with light of a second color different than the first color, wherein the light of the second color illuminates at least a majority of an entire volume of the container. One or more additional imagers of the container are captured by a second imager configured to filter out colors other than the second color. The one or more images and the one or more additional images are analyzed to detect particles within, and/or on an exterior surface of, the container.

    Abstract: A system is described to facilitate the characterization of particles within a fluid contained in a vessel using an illumination system that directs source light through each vessel. One or more optical elements may be implemented to refract the source light and to illuminate the entire volume of the vessel. As the refracted source light passes through the vessel and interacts with particles suspended in the fluid, scattered light is produced and directed to an imager, while the refracted source light is diverted away from the imager to prevent the source light from drowning out the scattered light. The system can therefore advantageously utilize an imager with a large depth of field to accurately image the entire volume of fluid at the same time, facilitating the determination of the number and size of particles suspended in the fluid.

    Abstract: An automated visual inspection (AVI) system may include at least one profile view imager having an optical axis that passes through an inspection object, a proximal polarizing film axially aligned with the optical axis, a liquid crystal device axially aligned with the optical axis, a distal polarizing film axially aligned with the optical axis, and at least one light source oriented to emit illumination toward the distal polarizing film. Alternatively, or additionally, an AVI system may include a profile view imager having an optical axis that enters a container through a side wall of the container, and a ring light that is coaxially aligned with a central axis of the container, below the container, and oriented to emit light toward a bottom of the container. The AVI system may also include a bottom imager coaxially aligned with the central axis and oriented to view the bottom of the container.

    Abstract: In a method for imaging a container holding a sample, the container is illuminated with a laser sheet that impinges upon the container in a first direction corresponding to a first axis. A plane of the laser sheet is defined by the first axis and a second axis orthogonal to the first axis. The method also includes capturing, by a camera having an imaging axis that is substantially orthogonal to at least the first axis, an image of the container. The method further includes analyzing, by one or more processors, the image of the container to detect particles within, and/or on an exterior surface of, the container.

    Abstract: A method for 3D imaging of a sample, in a vessel having a longitudinal axis orthogonal to a horizontal plane, includes capturing, by at least three cameras located at different positions around the vessel, respective 2D images of the sample. Each image comprises pixels having associated pixel values. The optical axis of a first camera is inclined or declined at a first angle relative to the horizontal plane, with the first angle being greater than or equal to zero degrees. The optical axis of a second camera is inclined or declined at a second, larger angle relative to the horizontal plane. The method also includes generating a 3D image of the sample based on the pixel values associated with the 2D image pixels, and one or more look-up tables that collectively indicate, for pixels in each image, expected paths for light traversing the vessel and the sample.

    Abstract: Fill-finish assemblies facilitating the manufacture of a drug delivery device are disclosed. The fill-finish assembly may include a container, an insertion mechanism, a fluid pathway connection assembly disposed between the container and the insertion mechanism, and a carrier. The insertion mechanism may include a delivery member and an insertion mechanism housing. The insertion mechanism may be configured to move the delivery member from a retracted position inside the insertion mechanism housing to a deployed position outside the insertion mechanism housing. The fluid pathway connection assembly may be selectively activatable to establish fluid communication between the container and the delivery member. The carrier may have a hollow interior containing at least a portion of each of the container, the insertion mechanism, and the fluid pathway connection assembly. The carrier may be configured to hold the container, the insertion mechanism, and the fluid pathway connection assembly in alignment with each other.
