Abstract:
1. A method of imaging one or more fluorescence indications from a device comprising an array of reaction sites, the method comprising: thermally cycling the array of reaction sites of the device, wherein the array of reaction sites of the device comprise at least about 384 reaction sites; transmitting one or more fluorescent emission signals derived from one or more samples in the array of thermally cycling reaction sites of the device along an imaging path coupled to the device and an optical lens system, wherein the one or more fluorescent emission signals are transmitted through a first multi-element optical train and a second multi-element optical train of the optical lens system; receiving the one or more fluorescent emission signals transmitted through the optical lens system at a detector; producing at least first and second images of the one or more fluorescent emission signals of the device at different wavelengths, wherein each single image simultaneously encompasses the array of reaction sites of the device; and limiting chromatic aberration of the first and second images along the imaging path.
