About Guangyin Technology Development

Guangyin Technology (光引科技, GlitterinTech) is a Chinese photonics company that develops silicon-based integrated optoelectronic chips for spectroscopy. Its core product is an on-chip spectrometer in which precise spectral modulation happens inside the optical chip, delivering ultra-high resolution, wide spectral range and high precision. The wavelength design is highly flexible, so the spectral range and resolution can be matched to the application, and the company cites near-infrared operation across a very wide band with resolution as fine as 0.01 nm in a millimetre-scale chip.

On top of the chip it offers spectrometer modules, button-sized spectral sensors that it describes as the smallest and most capable spectrometer modules in the industry, combining silicon photonics with AI algorithms to open near-infrared analysis to new applications. The product range also includes spectral analysis solutions and, as an extension of the same silicon photonics platform, optical computing chips and optical switching chips.

Target applications are smart wearables, chemicals and pharmaceuticals, high-end medical care, environmental monitoring, and food and agricultural products. The company's wearable pitch is non-invasive health monitoring: near-infrared spectra can be used to estimate indicators such as blood water content, lipids, lactate and glucose without punctures, in real time and in portable, low-cost devices, with data analysis and machine learning to identify health trends. It also runs a developer platform for its devices.

Guangyin sells chips, modules and analysis solutions to device makers, instrument makers and industrial users, and develops application solutions together with customers. It operates in the silicon photonics and miniaturised spectroscopy market, competing with conventional benchtop and MEMS spectrometers on size, resolution and integration.
