A device and method for detecting a signal from an analytical sample is provided. The device comprises a platen with a first and second surface, a number of collection structures extending from the second surface. Each collection structure has a capillary channel running along a common axis as the collection structure from the platen to a terminal end of the structure. Within the capillary channel are sample analytes of interest. On the first surface is disposed a number of optical elements, corresponding to each collection structure, each centered on a capillary channel. Each collection structure has a geometry that can concentrate an optical emission from within the capillary channel, along the entire length of the capillary channel, towards the first surface and optical elements, to a detection device, by means of either mirrored surface reflection or total internal reflection. The collection structure may also direct a light beam into the capillary channel. The present device can be used for non-imaging optical applications from the generated signal.
