The miniaturization of optical elements poses challenges for photoacoustic microscopy, where bulky components can hinder performance. The authors utilize meta-optics with sub-wavelength elements to enhance phase control and multifunctionality, demonstrating improved depth of field and performance over conventional lenses, potentially revolutionizing photoacoustic imaging setups.
