Optimized for Water/Gas Sensing and Disinfection, TO-can Package, 2X Temperature Stability
Brisbane, Australia, 2nd September, 2025 – Silanna UV is pleased to announce the release of its next generation Far UVC LED, the SF2-3T9B5L1-TB, which exceeds even the popular SF1 series, with UVC wavelengths down to 230nm (typical 233nm); doubled output power; and 2x improvement in temperature stability. This new SF2 UVC LED is encapsulated in a standard compact Transistor Outline (TO-can) package.
The SF2 is designed for precise detection and reliable disinfection in demanding environments, with the collimated ball lens providing a 17° effective beam angle. It is ideal for detection of nitrate (NO3) and nitrite (NO2) in water, and detection of carbon dioxide (CO2) and Nitric Oxide (NO) in gas. These features make this far UVC LED excellent for applications such as chemical and biological analysis, water quality monitoring, gas sensing, liquid chromatography, and disinfection.
SF2 Far UVC LED: Stability, Environmental Safety, Durability, High Output
These LEDs have an environmental advantage, as they contain no mercury, and the LEDs are far more robust than traditional UV lamps. The TO-can package format, with industry standard TO-39 footprint, consists of a header and a cap that together form a hermetically-sealed package. Electrostatic Discharge (ESD) protection is integrated.
The SF2 LED improves Far UVC products by doubling typical radiant intensity to 2 mw/Sr. But at the same time, this new product’s improved temperature stability minimises the impact when the temperature changes, keeping output power and wavelength stable to ensure quality detection readings. Thus, this product sets a new benchmark in Far UVC LED technology.
