Fibre Optic Readout of Microcantilever Arrays for Fast Microorganism Growth Detection

Figure 1

Photograph of fibre optic cantilever device. A collimated laser beam is focused into a line along a cantilever array using a convex cylindrical lens. The deflected signal from each cantilever is directed into one of eight optic fibres (one for each cantilever) using a concave cylindrical lens. The optical axis is maintained using two cage systems, which are mounted on two gothic arch XYZ translation stages. Horizontal distance from hole to hole is 25 mm on breadboard.
