Compact High-Resolution Metalens Doublet Microscope Advances Biomedical Imaging
- Researchers at Nanjing University have developed a metalens-based microscope with high resolution and a wide field of view.
- Metalenses offer thin, flat optical elements that can manipulate light waves effectively.
- Traditionally, off-axis aberrations have been a challenge for metalenses in microscopy.
- The new design uses a monolithic doublet configuration with specialized illumination to mitigate off-axis aberrations.
- The prototype achieves a 150-micrometer FOV and 310-nanometer resolution, surpassing previous meta-optical microscopy resolutions.
- The compact system is small in size and weight, making it practical for real-world applications.
- The microscope successfully imaged cervical cancer cells, showcasing its potential in medical diagnostics.
- The technology can be implemented in portable devices for remote clinics and environmental monitoring.
- The innovation balances high resolution and wide-field imaging, opening new possibilities in optical instrumentation.
- The metalens doublet with annular illumination marks a significant milestone in metasurface optics, inspiring innovations in various optical devices.
