Abstract

Fluorescence detectors are applied for various applications in biomedical research, e.g. for pH-sensoring or single-cell detection. Free space optical systems offer the advantage of compact and efficiently integrated systems with benefits in the terms of systems alignment and optical functionality. On the other hand, due to the lab-on-a-chip character many fluidic systems, such as segmented flow systems, are very compact and thus compatible with integrated optical systems. We discuss the potential of the integration of the segmented flow approach in complex free space optical microsystems. The design and realization of a highly integrated fluorescence detector is demonstrated. The system is fabricated by ultra precision micromilling which allows one to monolithically integrate freeform optical elements for optimized optical performance.
