Silanna UV Revolutionizes Far UV-C and Deep UV-C LEDs

Silanna UV has announced new far UV-C and deep UV-C LEDs that take advantage of the company's patented short period superlattice (SPSL) technology for industry-leading performance in the difficult-to-obtain 230 – 265 nm UV range – including the highest output power in any mass-produced UV LED at 235 nm.

The far UV-C 235 nm SF1 series and deep UV-C 255 nm SN3 series are both available in either 120-degree or 30-degree viewing angle SMD packages, making them ideal for a wide range of tasks. The 30-degree package's parabolic lens provides greater irradiance than even traditional UV lamps. Both the SF1 and SN3 series boast low power consumption and have exceptional operating lifetimes.

According to the company these new LEDs offer the perfect solution for various deep UV and far UV use cases such as sterilization, water and gas sensing, and instrumentation applications.

The 235 nm peak wavelength SF1 series comprises the 120-degree view angle (SF1-3C3FWL1), and the 30-degree (SF1-3U8P3L1). These far UV LEDs are effective for water quality detection of nitrate (NO3) and nitrite (NO2), gas detection and high performance liquid chromatography (HPLC). Sensing applications will be enhanced by the higher irradiance of the SF1-3U8P3L1's 30-degree collimated source design.
