Samsung Electronics has secured its fourth Korean patent titled "meta-lens and optical apparatus including the same," bolstering its next-generation optical portfolio.
The March-issued grant, Patent No. KR2778195, derives from a divisional filing of the original April 2019 application (KR1020190046940), which was initially refused. Since 2017, Samsung has filed 15 Korea patents featuring "metalens" in the title; as of April 27, four have been granted, one refused and ten remain pending.
Of the pending filings, two were co-filed with the University of Massachusetts—one in February 2019 (KR1020190017963) and another in May 2023 (KR1020230065878); the latter is not a divisional of the former.
Samsung said the newly granted lens overcomes the thickness limits of traditional curved optics by employing nanoscale metastructures in multiple layers. The design holds focal length steady across the visible spectrum while slashing size and weight, and it simplifies chromatic and other aberration control—making it ideal for image-sensor lenses and compact optical modules.
In February, Samsung and Pohang University of Science and Technology published in Nature Materials an achromatic metalens integrated with holographic displays, demonstrating high-resolution, distortion-free imaging for lightweight XR wearables, camera modules and sensing systems.
