Uv excimer lamp UV intensity detection can use UV sensor GFUV-T10GD-L

Ultraviolet excimer lamp is to obtain high-intensity excimer ultraviolet light with different monochromatic wavelengths such as 172nm, 222nm or 308nm by using excimer gas ratio. The ultraviolet light emitted by the excimer has single-spectral characteristics, narrow spectral lines and a monochromatic ultraviolet radiation spectrum, allowing it to be photoprocessed using a more concentrated power.

Excimer is a kind of unstable molecule, which is a kind of molecular state produced when the laser gas mixture is excited by external energy. It exists for only a few tens of nanoseconds, and then immediately returns to a less energetic state by spontaneous radiation transition, emitting photons, and finally breaking down into atoms. During the transition from the bound excited state to the weakly bound ground state, ultraviolet photon radiation is generated, and different excited states produce ultraviolet photons of different wavelengths. These photons typically have energies between 3.5-10 eV, which is enough to open most chemical bonds.

Xenon excimer xenon lamps using xenon produce ultraviolet wavelengths of 126 nm, 172 nm, 222 nm, 254 nm, 308 nm, etc., with a single wavelength and a narrow wavelength range. Currently, 172-nanometer excimer lamps need to be filled with nitrogen for protection. The light curing of UV coating has been applied in industry, after the ultraviolet light is irradiated to the solid surface, the pollutant organic molecules on the surface are truncated by strong light, are oxidized, and then decomposed into volatile substances such as oxygen and hydrogen, and finally evaporate, and the cleanliness of the cleaned surface is extremely high.

Compared with traditional mercury UV lamps, excimer UV lamps have super power, precise targeting, no mercury harm, environmental protection, recyclable and no secondary pollution. It has the advantages of large reaction area and short reaction time, and has a wide and unique application in microelectronics, medicine, material science, ecological environmental protection and other fields. The ultraviolet intensity of excimer lamps can be monitored using ultraviolet sensors, the industrial network agent of South Korea GENICOM ultraviolet sensor - GFUV-T10GD-L, based on gallium and aluminum nitride materials, schotky-type photodiode, photovoltaic mode operation, suitable for far ultraviolet monitoring and excimer lamp ultraviolet intensity monitoring.
