Deptrum
Deptrum (光鉴科技) is a Chinese 3D vision company founded in 2018 by three Silicon Valley scientists, including a former Apple depth-hardware lead. It builds full-stack 3D depth-sensing solutions - nanophotonic chips, structured-light and Time-of-Flight cameras, and AI perception algorithms - that let machines see and measure the physical world. Its hardware powers robots, smart cockpits, palm-payment terminals, smartphones and new-retail systems across finance, automotive and IoT.
Metalenz
Metalenz is a Boston-based deep-tech company that replaces stacks of curved glass lenses with a single flat, nanostructured semiconductor chip called a metasurface. Spun out of Harvard's Capasso Lab, it is the first company to mass-produce meta-optics, shrinking cameras and sensors for smartphones, biometrics, and 3D sensing. Its flagship Polar ID brings polarization-based, payment-grade face authentication to devices at a fraction of the size and cost of existing systems.
