The wavelength range technical parameters of the Shanghai 3S Tech photochemical reactor are designed to meet both scientific research and industrial needs. Its core spectral band covers the full spectrum from 250 nm to 975 nm, encompassing the ultraviolet (UV), visible light, and near-infrared (NIR) regions. The equipment utilizes high-purity narrow-wavelength LED light sources, supporting over 100 standard wavelength specifications within the 365 nm to 975 nm range. Additionally, customization allows for breakthroughs in the deep-UV band from 250 nm to 360 nm, meeting the demands of specialized applications such as photocatalytic degradation of pollutants and material surface modification.

In terms of light source control, the equipment supports independent adjustment of single wavelengths and combined output of multiple wavelengths, with a maximum light intensity of up to 1000 mW/cm² and an electrical power control precision of 10 mW, ensuring precise energy input. For different reaction systems, users can freely select from over a hundred monochromatic LED components. For example, a 365 nm light source can be used in drug synthesis to match molecular transition energy levels and enhance reaction selectivity, while in the development of photocatalytic materials, the wavelength can be adjusted to screen the material's photoresponse range and optimize light absorption efficiency.

The equipment has a light attenuation rate of less than 5% per year. When paired with a liquid-cooling temperature control system, it can maintain long-term wavelength stability, avoiding thermal effects that could interfere with experiments and ensuring high repeatability and reliability of experimental data.
