A suspension or solution for organic optoelectronic device is disclosed in this invention. The system and method obtains a collection of sets and a threshold value from an interface, and based at least in part on an identifiable similarity, such as an overlap or intersection, between the collection of sets the analysis component generates and outputs a candidate pair that at least equals or exceeds the threshold value. A spring biases the thimble filter and magnet toward the inlet port of the housing. Each microstructure includes a recess having a concave surface, and a protrusion formed around a periphery of the recess, wherein at least half of the concave surface is a mirror-like surface.
