GlitterinTech On-Chip Spectrometer Chips & Modules

GlitterinTech Limited was founded in 2021 by scientists from the University of Cambridge and lists its address in Xuzhou, China, with R&D centres in Xuzhou, Shanghai and Cambridge, UK. It develops photonic integrated circuits that shrink laboratory spectral analysis into chip-scale sensors for devices and instruments.

Its silicon photonics spectrometer chip uses computational spectroscopy on a millimetre-scale die, with near-infrared broadband operation and a stated resolution of up to 0.01 nm; spectral range and resolution can be tailored per application. A button-sized spectrometer module combines the chip with AI algorithms for integration into precision instruments and wearables. The company is also working on optical switching and optical computing chips. Customers are device makers in wearables, healthcare, pharmaceuticals, environmental monitoring and food inspection.

• Spectrometer chip: silicon photonics computational spectrometer on a millimetre-scale die.
• High resolution: stated resolution of up to 0.01 nm in the near infrared.
• Spectrometer module: button-sized spectral sensor combining the chip and AI algorithms.
• Custom spectral design: range and resolution tailored to each customer application.
• Coupling options: chip edge coupling and vertical coupling configurations.
• Expanding portfolio: optical switching and optical computing chips under development.

Vietnamese agricultural exporters can embed spectral modules in handheld testers to check moisture or quality of coffee, rice and fruit. Pharmaceutical and chemical plants can add inline spectral sensors for raw-material checks. Electronics manufacturers in Vietnam can co-develop wearables with built-in spectral sensing.

A millimetre-scale chip replaces bulky spectrometer optics, so spectral sensing fits into wearables and handheld devices. The company states resolution of up to 0.01 nm. Spectral range and resolution can be customised for each application. According to a 2026 funding report, the company estimates chip production cost below 20 USD versus 100 to 2,000 USD for mainstream modules.

Spectral sensing is moving from laboratories into wearables, phones and inline industrial sensors as chip-scale spectrometers lower size and cost. Food safety, agricultural quality and pharmaceutical inspection all need fast, non-destructive measurement. Southeast Asian food exporters and electronics manufacturers are potential users of low-cost spectral modules.

Founded in 2021 by University of Cambridge scientists; R&D centres in Xuzhou and Shanghai, China and Cambridge, UK. Founder Cheng Qixiang holds a Cambridge PhD. Raised a pre-Series A round in July 2026 from investors including Shanda Capital, Yangtze Optical Fibre and Cable Fund and CAS Star, per Dealroom.
