1. A method for carrying out process steps for nucleic acid sequencing, comprising:
- a) providing a first chip in a first flow cell, a second chip in a second flow cell, nucleic acid to be sequenced, nucleic acid sequencing reagents, a first camera and a second camera;
b) introducing said nucleic acid to be sequenced and said nucleic acid sequencing reagents into said first and second flow cells under conditions such that, while said first chip in said first flow cell is undergoing one or more reaction steps, said second chip in a second flow cell is being scanned and imaged with said first camera; and
c) scanning and imaging said first chip in said first flow cell with said second camera.

Abstract
An imaging system for exciting and measuring fluorescence on or in samples comprising fluorescent materials (e.g. fluorescent labels, dyes or pigments). In one embodiment, a device is used to detect fluorescent labels on nucleic acid. In a preferred embodiment, the device is configured such that fluorescent labels in a plurality of different DNA templates are simultaneously detected.
