Guangna Siwei completed a new round of tens of millions of yuan in financing to accelerate the mass production of AR optical modules

Recently, Guangna Siwei Optoelectronics Technology Co., Ltd. completed Series A financing, with investors including Danlu Capital, Qianhai Amber Yongyu Investment and Nano Fund.

The funds will focus on the expansion of the scientific research team and the optimization of the silicon carbide waveguide etching mass production process to accelerate the consumer-level mass production of AR optical modules.

Information shows that Guangna 4D was established on December 8, 2021. It focuses on the manufacturing technology of diffractive optical waveguides and also lays out the two main production process directions of surface relief gratings: nanoimprinting process and etching process.

In 2022, Guangna 4D made a breakthrough in AR waveguide etching process preparation technology. In 2023, it achieved a breakthrough of 110° ultra-wide field of view. In 2024, it completed silicon carbide DUV lithography and etching process research. The product achieved a single-chip full-color display with a thickness of only 0.7mm and a weight of only 4g, completely eliminating the rainbow pattern effect.

At present, Guangna's four-dimensional nano-imprinted AR waveguide has achieved large-scale mass production and shipment, and has also built an 8-inch AR waveguide etching pilot line.
