We propose and demonstrate the adoption of the compact disc optical pickup technology for Raman microspectroscopy. We utilize both the focusing and the 2D scanning capabilities of an optical pickup for implementation of 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 microstructures. This system will be useful for table-top biological analyzers and other remote medicine applications.
