Integrated optoelectronic read head and fluidic cartridge useful for nucleic acid sequencing
First Claim
1. A detection apparatus, comprising(a) a carriage comprising a plurality of microfluorometers,wherein the plurality of microfluorometers form a read head,wherein the microfluorometers are permanently fixed in the read head such that the microfluorometers are not independently moveable with respect to each other in a direction parallel to the common plane,wherein the read head comprises a co-molded assembly of the plurality of microfluorometers,wherein each of the microfluorometers comprises an objective having a field diameter of at least 1 mm,wherein the plurality of microfluorometers is positioned to simultaneously acquire a plurality of wide-field images in a common plane, andwherein each of the wide-field images is from a different area of the common plane;
- (b) a translation stage configured to move the carriage in at least one direction parallel to the common plane; and
(c) a sample stage configured to hold a substrate in the common plane.

Abstract
A detection apparatus having a read head including a plurality of microfluorometers positioned to simultaneously acquire a plurality of the wide-field images in a common plane; and (b) a translation stage configured to move the read head along a substrate that is in the common plane. The substrate can be a flow cell that is included in a cartridge, the cartridge also including a housing for (i) a sample reservoir; (ii) a fluidic line between the sample reservoir and the flow cell; (iii) several reagent reservoirs in fluid communication with the flow cell, (iv) at least one valve configured to mediate fluid communication between the reservoirs and the flow cell; and (v) at least one pressure source configured to move liquids from the reservoirs to the flow cell. The detection apparatus and cartridge can be used together or independent of each other.
