Spectrum: The "Fingerprint" of Matter
A spectrum is formed when polychromatic light is dispersed into monochromatic components, sequentially arranged by wavelength or frequency. Since different substances exhibit distinct characteristic spectral lines, spectra are often referred to as the "fingerprint" of matter.

Donghong Photonics: Revolutionizing Spectroscopy with Chip-Scale Innovation

Amid the photon industry revolution, Donghong Photonics (Shanghai), a high-tech enterprise based in Baoshan, has emerged as a disruptor. Focusing on critical "bottleneck" technologies, the company leverages micro-nano chip technology to miniaturize bulky spectrometers into compact, chip-scale devices.

The Birth of Chip-Scale Spectrometers

• On factory floors, a fingernail-sized chip embedded in inspection equipment instantly analyzes chemical composition, verifying material purity.
• In agricultural fields, drones equipped with micro-spectrometers detect crop diseases via spectral signatures.

Spectroscopy is transitioning from labs to real-world applications—yet traditional spectrometers remain bulky, expensive (costing up to millions of RMB), and operationally complex, limiting widespread adoption.

Breakthrough: Tunable Closed-Loop Micro-Spectroscopy

Donghong Photonics integrates photonics chips, nano-optics, and spectral informatics to pioneer a "tunable closed-loop micro-spectroscopy architecture." This innovation enables:
✅ Micro-nano photonic chips that consolidate optical/detection systems onto a single chip.
✅ Completed tape-out with performance exceeding design targets.

Unmatched Advantages

1. Size: 1,000x smaller than mainstream products (e.g., Hamamatsu, Ocean Optics).
2. Cost/Power: Infrared detector pixel requirements reduced to 1% of conventional systems, slashing manufacturing costs and energy use.
3. Performance:
   • Spectral range: 900–2500 nm (covering mid-wave infrared).
   • Superior resolution, SNR, and bit depth.
4. Market Impact: Breaks foreign monopolies in handheld mid-IR spectrometers, achieving 100% IP ownership.

Applications span standalone sensors, integrated analysis devices, and ODM solutions, realizing the vision of "spectroscopy for all industries."

Government-Enterprise Synergy Accelerates Growth

On December 16, 2024, Donghong Photonics inaugurated its R&D center, attended by:

• Academic experts from the Shanghai Institute of Technical Physics (CAS).
• Officials from Baoshan District Science Commission and Miaohang Town Government.
• Investors including the Yangtze River Delta National Technology Innovation Center and Shanghai Baoshan Technology Transfer Co., Ltd.

Policy and Funding Support

• Backed by Baoshan’s "invest-first, equity-later" model and the Delta Center’s "grant-investment hybrid" funding.
• Miaohang Town provides talent incentives (e.g., housing subsidies, residency permits) to attract top researchers.

Milestones & Future Roadmap

Within a year of founding, Donghong Photonics has:
🔹 Established R&D and production pipelines.
🔹 Launched flagship products.

Next-phase support will cover business strategy, team-building, governance, market expansion, and capital financing—positioning the company as a global leader in compact spectroscopy.
