Crystal IS, Asahi Kasei Announce New Record for Single-Chip Device Output

Asahi Kasei, Green Island, New York, and Düsseldorf, Germany, demonstrated the company’s next-generation Klaran single-chip UVC LED, which emits the ideal germicidal range of 260-270 nm. This higher output device will be used to accelerate the adoption of UVC LEDs and hasten the widespread replacement of low-pressure mercury lamps.

While the new device will retain the Klaran compact 3.5 mm x 3.5 mm package and solder pad design to allow backward compatibility with existing customer designs, the higher output will allow UVC LEDs to meet the performance and cost targets needed to expand into new applications in high-flow water and air treatment.

The new single-chip UVC LED design uses a rigid fused silica lens and a thin layer of proprietary UVC transparent resin developed by Asahi Kasei specifically to withstand the intense UVC output. The rigid fused silica lens allows higher transmission of the UVC light, which ensures stable long-life performance and high-temperature stability.
