South Korea's LetinAR Builds Thumbnail-Sized Optics for the AI Glasses Era

TechCrunch·low signal

South Korean startup LetinAR is developing miniaturized optical components the size of a thumbnail that could become the optical backbone of AI-powered smart glasses. With Google previewing Android XR glasses at I/O today and Meta/Anduril building military AR headsets, the supply chain for wearable AI optics is becoming a strategic chokepoint. LetinAR is positioning as a component supplier rather than a glasses maker — the picks-and-shovels play for the emerging wearable AI market.
