Abstract:
An illumination system includes a surface configured to have an imaging target placed thereon, a light source, a beam splitter and at least a first mirror. The beam splitter is configured to split the beam of light from the light source and the first mirror is configured to reflect a first beam from the beam splitter onto the surface with the imaging target. An imaging system includes an imaging surface configured to have an imaging target placed thereon, a mirror, and a capturing device. The capturing device is configured to capture an image of the imaging target through a path of emitted light that extends from the imaging target, reflects off of the mirror, and to the capturing device. The mirror, the capturing device, or both are configured to move in a diagonal direction with respect to the imaging surface to reduce a length of the path of emitted light. Systems and methods to calibrate an imaging system to remove or reduce non-uniformities within images of samples due to imaging system properties.

Abstract:
A system and method to perform calibrated assays in reusable microplates, the method including steps of illuminating a microplate having wells and a microplate identifier, with a probe signal, detecting an uncalibrated return signal, reading the microplate identifier, retrieving, from a database by use of the microplate identifier, a calibration factor for each well in the microplate, calibrating the return signal for each well by use of the respective calibration factor for said well, and outputting the calibrated return signal as said calibrated assay. The system includes a microplate, comprising a plurality of wells and a microplate identifier, a reader to read the microplate identifier, a probe signal source and return signal detector, wherein a return signal comprises a probe signal after interaction with the plurality of wells, a calibration database to store the microplate identifier associated with return signal measurements, and a processor to perform the method.
Abstract:
Embodiments disclosed herein provide reagents and methods for high-throughput screening of nucleic acid sequence variations in nucleic acid containing specimens. Nucleic acid specimens to be screened are loaded into separate discrete volumes. Optically encoded particles are used to deliver primers to amplify one or more sequences comprising the nucleic acid sequence variation. The optically encoded particles may be delivered to the discrete volumes randomly resulting in a random combination of optically encoded particles in each well, or a unique combination of optically encoded particles may be specifically assigned to each discrete volume. The observable combination of optically encoded particles may then be used to identify each discrete volume.
Abstract:
An image based photometer includes a light source adapted to hold a well plate having multiple wells for testing samples, the light source providing a source of broadband white light for transmission through the multiple wells. A sensing surface is positioned opposite the light source to receive light transmitted through the multiple wells and shield ambient light from transmission through the wells.

Method includes positioning a first carrier assembly on a system stage. The carrier assembly includes a support frame having an inner frame edge that defines a window of the support frame. The first carrier assembly includes a first substrate that is positioned within the window and surrounded by the inner frame edge. The first substrate has a sample thereon. The method includes detecting optical signals from the sample of the first substrate. The method also includes replacing the first carrier assembly on the system stage with a second carrier assembly on the system stage. The second carrier assembly includes the support frame and an adapter plate held by the support frame. The second carrier assembly has a second substrate held by the adapter plate that has a sample thereon. The method also includes detecting optical signals from the sample of the second substrate.
