Tunable High Power Laser

The Division of Biomedical Physics, Office of Science and Engineering Laboratories (OSEL) at CDRH performs regulatory science research on novel optical diagnostic devices to accelerate patient access to innovative, safe, and effective medical devices. This procurement supports the assembly of a customizable, research-grade Photoacoustic Imaging (PAI) system to support development of regulatory science tools under OSEL's Optical Diagnostics and Therapeutics Program.

A high-quality, state-of-the-art PAI system is essential to ensuring our regulatory science efforts are relevant to current PAI-based medical devices and will have maximal impact on affected stakeholders. Scope The procurement supports regulatory science tools development for the Photoacoustic Imaging (PAI) sub-program within the Optical Diagnostics and Therapeutics Program.

A modern, high-quality PAI system is essential for regulatory science efforts, including human subjects research, to remain relevant to current generation PAI devices in today's market and those undergoing regulatory evaluation. This equipment will enable completion of research objectives described in OSEL's Medical Imaging and Diagnostics program charter.
