ABSTRACT:
Devices are provided comprising reflecting channels for directing horizontally a vertical light beam through a multiplicity of streams. The devices provide particular applications in microfluidics, where streams of narrow cross-sectional dimensions are involved. Desirably, channels having 45° walls are provided for directing the beams and where the streams are divided by walls, the walls are at substantially 90°. Methods of fabrication of the devices are provided.
