Metalens
Metalens is a planar optical element based on metasurface technology, using subwavelength nanostructures to precisely control the phase and propagation of light. Unlike conventional refractive lenses that rely on curved surfaces and thickness variation, Metalens enables beam shaping and imaging within an ultra-thin, flat structure, supporting compact and highly integrated optical designs.
Compared with traditional multi-level diffractive optical elements (DOE), Metalens adopts a uniform-height nanostructure design to achieve phase modulation through geometry or orientation, eliminating shadowing effects and maintaining stable optical efficiency over a wide angular range. This makes Metalens suitable for wide field-of-view imaging, high-NA systems, and large-angle beam shaping applications.
Metalens also allows multiple optical functions—such as beam shaping, imaging, and polarization control—to be integrated into a single element, significantly simplifying optical system architecture and reducing assembly complexity.
Manufactured using semiconductor-grade processes, Metalens offers high precision, excellent consistency, and reliable mass-production performance. Its compatibility with automated manufacturing enables stable quality, high yield rates, and dependable integration into modern optical modules.
