Claim 11:
12. A microfluidic device, comprising:
a substrate;
a lid mounted to the substrate and forming a discrete microfluidic chamber between structures including an interior surface of the lid and a portion of the substrate, said lid comprising an inlet and a vent positioned relative to one another to facilitate loading of fluid to the discrete microfluidic chamber via capillary action, wherein the discrete microfluidic chamber has a volume of from 1 nl to 100 μl; and
a microchip mounted to the substrate, a portion of the microchip positioned within the discrete microfluidic chamber and a second portion of the microchip positioned outside of the discrete microfluidic chamber;
wherein the lid further comprises an exterior surface modification selected from a Fresnel lens, a crenulated surface, a non-uniform thickness, a thin film optical filter, and a combination thereof.
