What Raysees does

Raysees (瑞识科技 / Ruishi Technology) is a Shenzhen-headquartered, fabless VCSEL (Vertical Cavity Surface Emitting Laser) chip and integrated optical engine provider founded in 2018 by US returnee PhDs. The company operates a vertically integrated platform from in-house epitaxial design and device engineering through advanced packaging and system-level optical integration, supplemented by proprietary optical design tools purpose-built for VCSEL freeform and diffractive optics where mainstream optical software lacks mature support. Its product portfolio spans three chip lines — Consumer VCSEL (650–1064 nm wavelengths across single/multi-junction, addressable, and random-array designs), Automotive Certified VCSEL (AEC-Q102 / IATF 16949 qualified multi-junction high-power chips up to 150 W for LiDAR, ADAS, and in-cabin sensing), and High-Speed Datacom VCSEL (per-lane 100G and beyond for AI cluster interconnects) — alongside the ViOE optical engine module family (PRAY, XRAY, SRAY, TRAY), a high-power ns-pulse VCSEL driver board, and a product customization service. The company assembles these building blocks into six application solutions: robotics sensing, optical interconnect, medical / beauty (via VIPE), advanced manufacturing heating, automotive, and consumer electronics, with cumulative shipments exceeding 200 million chips to over 100 customers worldwide.

Raysees runs a direct B2B sales-led model with enterprise field sales targeting automotive OEM supply chains and inbound sales via website consultation, customization, and contact forms. Pricing is quote-based with no public list. Volume manufacturing runs through a >4,000 sqm Hefei center (5KK/month emitter capacity, in production since December 2021) supported by R&D offices in Xiamen and Xi'an, leveraging leading global epitaxy and wafer foundries under a 100% domestic supply chain model with >90% wafer yield. The company has raised a Series B+ (~100M CNY in March 2024) and a Series C (hundreds of millions RMB in January 2026, led by Photon Strong Chain Fund, Hefei Industrial Investment, Shenzhen Capital Group, Xi'an Financial, West High Investment Hongyi Fund, Open Source Innovation, and Agricultural Bank Fund), with cumulative shipments exceeding 200 million units and four consecutive years of high-speed revenue growth. Customer segments are diversified across automotive (leading NEV OEMs), consumer electronics (>10M units delivered), AI data center / optical interconnect, robotics, medical / beauty, and advanced manufacturing, with automotive qualifications and >150 filed patents forming the core of its competitive position.
