Nika Optics (Tianjin) Co., Ltd., established in July 2022, is a high-tech company dedicated to the research, development, and production of consumer-grade volumetric holographic AR waveguide optical display devices. The company has independently established the first domestic production line for developing volume holographic optical waveguides, with an annual output of 100,000 AR glasses optical waveguides, achieving small-scale production. The company's volume holographic AR glasses optical waveguide products have the advantages of low cost for mass production, high diffraction efficiency, ultra-low light leakage ratio, and no rainbow pattern, making them a cost-effective solution for consumer-grade AR glasses. The in-vehicle AR-HUD products feature small size, low cost, and adaptability to all vehicle models, making them the preferred solution for current intelligent cockpits.
