Analytical devices having dichroic prism arrays
First Claim
1. An analytical system comprising:
- an analysis chip comprising an array of patches, each of the patches comprising nanoscale regions that emit fluorescent light when illuminated;
a two-dimensional (x, y) array of dichroic prisms, each prism comprising a dichroic element that diverts illumination light up in the z dimension of the array to a patch on the analysis chip above it, wherein each dichroic element transmits fluorescent light emitted by the patch that it illuminates, whereby the emitted light from each patch passes down through each dichroic prism; and
a detector below the array of dichroic prisms that detects the transmitted fluorescent light.

Abstract
Apparatus, systems and methods for use in analyzing discrete reactions are provided. The analytical devices of the invention use an array of nanoscale regions (a chip) that has discrete patches, for example, patches of nanoscale regions. In some embodiments an analytical system is provided that has an analysis chip with an array of patches, each of the patches comprising nanoscale regions that emit fluorescent light when illuminated. The system has a two-dimensional (x, y) array of dichroic prisms, each prism comprising a dichroic element that diverts illumination light up in the z dimension of the array to a patch on the analysis chip above it. Each dichroic element transmits fluorescent light emitted by the patch that it illuminates, whereby the emitted light from each patch passes down through each dichroic prism. The analytical system also has a detector below the array of dichroic prisms that detects the transmitted fluorescent light. Such systems are useful for monitoring many analytical reactions at one time including single molecule sequencing reactions.

10. A method for providing excitation illumination to an array of patches on a chip, wherein the patches emit fluorescent light, comprising:
-
providing, below the chip, a two-dimensional (x, y) array of dichroic prisms, each prism comprising a dichroic element; sending excitation illumination light into the array of dichroic prisms such that each dichroic prism diverts illumination light up in the z dimension to a patch on the chip above it, stimulating fluorescent emission from the patches; whereby the emitted light from each patch passes down through the dichroic prism that illuminated that patch to a detector. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
