Abstract
In this paper a compact fluorescence detection system for on-chip analysis of μm-sized beads is presented. The system comprises a cheap optical pickup with integrated functionalities that are used for the detection. Furthermore some other optical components are added for the fluorescence detection. Another part of the system is the microfluidic chip which contains liquid channels and optical markers used for the autofocus and channel find algorithms. Within one minute the channel of interest is found and fluorescent beads are detected in the microchannel without the need for dynamic focusing, since a two-dimensional scan across the channel width is performed.
