  • Publication number: 20210215687
    Abstract: An optical imaging system (100) includes a frame (102) designed to provide mechanical coupling between a first stage (104) and a second stage (106), a sample holding region (108) located on the first stage (104), a lens arrangement, and a sensor array. The lens arrangement is disposed between the first stage (104) and the second stage (106) and is designed to receive light from a sample at the sample holding region (108) on the first stage. The lens arrangement has a numerical aperture less than 0.1. The sensor array is coupled to the second stage (106) and is designed to receive light passing through the lens arrangement.

  • Patent number: 7758814
    Abstract: A microfluidic fluid distribution manifold includes a common port and a plurality of fluidic channels spirally wound around the common port. Each fluidic channel connects the common port to an independent port and provides essentially the same flow resistance to a fluid flowing therethrough. A fixture for the flow restrictor allows fluid flows to be communicated between the flow restrictor and a larger system such as a parallel reactor system.
