Fresh off my coverage of the Blackview BV300 AI smart glasses, a compelling new contender has emerged in the augmented reality space. Developed by a Hong‑Kong‑based engineering team, the Nimbo X1 — billed as the world’s lightest full‑color AR smart glasses — is set to kick off its global crowdfunding campaign on Kickstarter. Weighing only 49 grams, it hits this feather‑light benchmark thanks to cutting‑edge silicon‑carbide waveguide technology.
Optical Breakthrough: MicroLED Paired with Silicon Carbide Waveguide
Powering the Nimbo X1 is a compact optical system combining a tiny MicroLED light engine and full‑color diffractive silicon‑carbide waveguides from Guangna Siwei. The optical module occupies just 0.40 cc, delivering peak brightness of 1,500 nits alongside a smooth 60 Hz refresh rate.
Silicon carbide marks a meaningful upgrade over traditional glass waveguides. Conventional glass waveguides reach roughly a 2.0 refractive index and need stacked multi‑layer structures for full‑color output, adding bulk and creating optical signal loss. Silicon carbide delivers a much higher 2.7 refractive index, enabling full‑color projection within a single‑layer waveguide. This unlocks a wider field‑of‑view while drastically cutting weight — the same core optical material concept previously trialled on Meta’s Orion prototype AR glasses.
Developer‑Centric Open Ecosystem
More than a regular consumer wearable, Nimbo X1 is built first for developers and content creators. It ships with open API and SDK access, allowing third‑party developers to build custom applications for diverse real‑world use cases. Out‑of‑box features include AI voice assistant support, real‑time bilingual translation, AR navigation, on‑glass teleprompter, local video playback, smartphone message alerts and customizable AR information dashboards.
Battery Performance & Wearable Practicality
To sustain full‑color AR display performance, the glasses pack a 310 mAh semi‑solid‑state battery. At 49 grams, the hardware reflects careful engineering trade‑offs. Industry research notes AR glasses ideally sit at or below 40 grams for broad‑market comfort and user adoption; the silicon‑carbide design brings Nimbo X1 very close to this target threshold.
Production Roadmap & Supply‑Chain Partners
The Nimbo X1 has finished engineering validation. Mass manufacturing is scheduled to start October 2026, with unit shipments planned for late October. Production will be handled by ODM Xiaoman Future, the manufacturer behind the Coray Air 2 smart glasses.
For its part, waveguide supplier Guangna Siwei continues ramping output. After opening its mass‑production line in 2023, the firm projects annual production capacity will hit 1–1.5 million waveguide sets in 2026 once new lines come online.
Industry Landscape & Key Challenges
Nimbo X1 arrives during a high‑growth period for AR smart glasses. Meta, Apple and Snap are all heavily investing in and launching next‑generation AI‑enabled eyewear products.
Even so, silicon‑carbide hardware carries steep manufacturing barriers. Second only to diamond in hardness, silicon carbide resists standard nanoimprint fabrication and demands complex semiconductor‑grade etching workflows. Industry sources estimate one bare silicon‑carbide substrate wafer costs 600‑700 RMB, and low production yields push overall expenses even higher. How well the Nimbo X1 team navigates these supply‑chain constraints will define the product’s real‑world success.
What to Expect Next
Exact Kickstarter launch timing and retail/crowdfunding pricing remain unannounced. The project’s pre‑launch Kickstarter page is already live for early supporters and developers to follow. If the team delivers on its technical promises, Nimbo X1 could represent a key milestone: making lightweight, full‑color AR hardware more accessible, while prioritizing developer flexibility to expand what smart glasses can do.
