MPAM-200 is an in vivo imaging platform of small animal that uses photoacoustic microscopy technology based on a transparent ultrasound transducer to achieve high speed, high resolution, and a wide imaging field of view (FOV). The perfect combination of fast laser scanning excitation and transparent ultrasound transducer reception gives the MPAM-200 excellent performance: tens of microns of lateral resolution, centimetre-level FOV, and frame rates in the seconds. It uses reflective coaxial confocal mode for 2D and 3D imaging with depth-coded reconstruction.

MPAM-200 offers multimodal optical interfaces for white light, fluorescence, NIRS, OCT, etc. It is the ideal solution for small animal imaging applications in preclinical research, enabling high-resolution and multimodal imaging of tissues and organs. Its innovative design bridges the gap between detailed structural analysis and functional imaging, making it a versatile tool for life science research.
