How TDK's Meta-Reflector Retinal Projection Differs from Waveguides and BirdBath

TDK's AR display solution uses a 150 nm thick meta-optic reflector in place of a conventional curved mirror, forming images through direct retinal projection (DRP). The reflective film has a visible-light transmittance of about 80%, and the current demonstration is still a monochrome prototype. Full-color demonstrations and mass production remain several years away, while consumer-level costs and processing yields are also key hurdles.

Conant Optics Enters Core Lens Supply Chain for Qwen AI Glasses N1 Series

Conant Optics supplies 23 lens SKUs each for the Qwen AI Glasses N1 and N1 Pro, and serves as a core supplier of plano and myopia prescription lenses. It is the exclusive supplier of 1.74 high-index lenses, high-value colorful lenses and smart photochromic lenses.

Its Shanghai base plans to add four dedicated production lines for lens lamination and complete-unit packaging.

XGIMI and Dangbei Enter AI Glasses: Which Optical Capabilities Can Projector Makers Transfer?

XGIMI and Dangbei have entered the AI glasses arena, and the article frames this as a business exploration under pressure in their core projector operations, drawing on their accumulated optical engine and microdisplay expertise. XGIMI MemoMind One began domestic pre-sales on October 15 at 2,294 yuan after the national subsidy; the AI note-taking glasses co-developed by Dangbei and DingTalk launched on October 13, priced from 1,299 yuan. Runto Technology notes that experience in optical engine miniaturization and image quality tuning can be reused, but near-eye imaging, wearable design, software ecosystems and eyewear retail channels remain real challenges.

Where Is AI/AR Glasses Funding Heading in 2026? Waveguides and Microdisplays Draw Capital Faster

In 2026, AI/AR glasses funding is tilting toward upstream waveguides and microdisplays, and the article argues that investment logic is shifting toward mass-production delivery and scarce capacity. According to incomplete statistics, as of October 2026 more than 37 funding rounds had been publicly disclosed across the domestic industry chain, with a total disclosed amount of about 9 billion yuan. Crystal Optech's C+ round exceeded 1 billion yuan, while MicroJewel Optoelectronics raised several hundred million yuan in a MicroLED Pre-A round.

Silicon Carbide Joins the Mass-Production Race as a Next-Generation Material for AR Optics

Silicon carbide AR waveguides are moving toward wafer-level manufacturing and small-volume production, but low-cost, high-volume consumer shipments remain some way off. A recent preprint from the Zhejiang Provincial Key Laboratory of 3D Micro/Nano Fabrication and Characterization, the Institute of Optoelectronics at Westlake University, and the Mude Micro-Nano team presents a full-color silicon carbide diffractive waveguide measuring 0.35 mm thick and weighing 1.98 g, with patterning of four pairs of lenses demonstrated on an 8-inch SiC wafer. The high refractive index helps widen the field of view and enable monolithic full color, but manufacturing challenges remain, including consistency of optical-grade substrates, micro- and nanofabrication of hard and brittle materials, and light leakage at packaging interfaces.

How Four Diffractive Optical Waveguide Pathways Drive Volume Manufacturing

SRG diffractive optical waveguides use four complementary pathways - nanoimprint, DUV lithography etching, SiC substrates and single-layer full color - to improve mass production, precision, field of view and image quality respectively. The article cites AAC Technologies' single-layer full-color SRG mass production yield of over 80%, a 52-degree FOV for the SiC solution, and the commissioning of Goertek Optics' 12-inch DUV lithography etching production line. Plans for million-unit-level capacity and ramp-up do not mean the industry as a whole has achieved stable million-unit-scale delivery; cost, yield and whole-device integration remain the next hurdles.

Fanchuangwei High-Transparency Optical AR Lens Project Lands in Taizhou with Total Investment of About RMB 550 Million

Shanghai Fanchuangwei Technology's high-transparency optical AR glasses lens project has settled in Huangyan, Taizhou, to be carried out in two phases by Fanke Technology (Taizhou), with total investment of about RMB 550 million. Phase one, at about RMB 150 million, plans to complete an innovation center and pilot production line by 2027. Phase two, at about RMB 400 million, targets annual output of 100 tonnes of high-purity silicon carbide optical material by 2028. Aimed at AI glasses and AR terminals, the project covers the full chain from optical materials and etching processes to optical devices.

Leqi second-generation AI glasses outlook: four optical challenges for diffractive waveguides

The article argues that AI capabilities can be upgraded over the air, but the optical experience of a diffractive waveguide is hard to fix once finalized. The development of Leqi's second-generation AI glasses focuses on four engineering challenges: hiding the grating, suppressing rainbow artifacts, thinning the lens, and reducing reflections while preserving brightness. These are also the issues consumer AI glasses must solve to look like ordinary eyewear.

Are DOE and Metasurfaces the Same Thing?

Citing Yole's 2025 diffractive optics report, the article notes that metasurfaces are a nanoscale subclass of DOE diffractive optical elements, not a replacement. The two have diverged in physical mechanisms, manufacturing routes and industrialization stages: traditional DOEs support today's volume production of AR optical waveguides, while metasurfaces carry future upgrades.

The Other Side of the First Year of Waveguide Mass Production: Capacity Is in Place, but Is Yield Keeping Up?

The article argues that 2026 is the first year of optical waveguide mass production, with multiple production capacities of one million units coming online, but capacity expansion does not equal stable mass production. The core barrier has shifted from whether it can be done to whether it can be done consistently at high yield. The three major bottlenecks in materials, processes and inspection are interlinked, requiring end-to-end system capabilities.

Industry Analysis: Silicon Carbide Waveguides Shift from Performance Option to Mass Production Essential

An OFweek article analyzes how silicon carbide optical waveguides are moving from an alternative AR performance material to a core element of mass production, with materials, chips and modules all scaling up simultaneously. It cites actions including Aifalong's oversubscribed Series B round of more than 100 million yuan to build an 8-inch silicon carbide metasurface optical waveguide chip production line, Guangna Siwei's financing of nearly 200 million yuan, and Goertek Optics' F50Se module achieving a 50-degree field of view. The author believes cost, processing yield and supply chain maturity remain the three hurdles before large-scale deployment, with the current average price of a SiC waveguide chip at 250-350 US dollars.
