We propose and demonstrate the adoption of the compact disc optical pickup technology for Raman microspectroscopy. We utilize both the focusing and the 2-dimensional lateral scanning capabilities of the optical pickup for implementing a miniaturized microspectroscopy system. The resolution of this pickup-based system is characterized by scanning polystyrene microspheres. We test the completed microspectroscopy system by obtaining Raman images of Adenine microstructurcs. This system will be particularly useful for table-top biological analyzers and other remote medicine applications.
