Abstract:
1. An apparatus for imaging one or more selected fluorescence indications from a microfluidic device, the apparatus comprising: an imaging path coupled to at least one chamber in at least one microfluidic device, wherein the microfluidic device is an elastomeric microfluidic device and wherein the at least one chamber is a closed reaction chamber, the imaging path providing for transmission of one or more fluorescent emission signals derived from one or more samples in the at least one chamber of the at least one microfluidic device, the chamber having a chamber size, the chamber size being characterized by an actual spatial dimension normal to the imaging path; and an optical lens system coupled to the imaging path, the optical lens system being adapted to transmit the one or more fluorescent signals associated with the chamber, the optical lens system being further adapted to reduce a size of the actual spatial dimension to a determined level and to transmit the one or more fluorescent emission signals associated with the chamber at the reduced size at the determined level, wherein the reduced size of the actual spatial dimension and the actual spatial dimension are characterized by a ratio of less than 0.9.
