More Info on Crystal IS

Crystal IS manufactures UVC LEDs based on Aluminum Nitride substrates which provide industry-leading light output and lifetime in the range of 250 nm – 280 nm for disinfection and measurement applications. 



Klaran LEDs

Klaran UVC LEDs are designed to provide effective, efficient disinfection for water, air and surfaces. Based on Crystal IS’ aluminum nitride substrates, these LEDs emit ultraviolet...

Optan LEDs

Optan LEDs are used in sensors to develop data networks that collect and analyze data in real-time.

Press Releases

The data in this chart shows the operation of Klaran LEDs with a rigid fused silica lens and proprietary UVC transparent resin by Asahi Kasei. Typical operating currents (350 - 500 mA) result in 130 - 160 mWs of optical UVC LED power output. The test results convey that the Klaran with silica lens offers 60% greater WPE and mW output at the same current as the non-lens version. The Klaran diagram below the chart visually represents the components of the engineering sample.

Crystal IS and Asahi Kasei Announce New Record for Single-Chip Device Output and Immediate Engineering Sample Availability of Their Upcoming 160 mW UVC LED

The new 160-mW LED marks a significant 60% increase over prior Crystal IS devices while retaining the optimal wavelength range (260-270 nm) for germicidal efficacy.
Crystal IS in-house VEKTREX systems that enable them to perform lifetime testing of large quantities of LEDs at multiple temperatures and driving currents.

Crystal IS announces lifetime characterization data for its Klaran LA UVC LED with a projected L70 Rating of 25,000 hours

The data demonstrates that a set of Klaran LA LEDs operating with a junction temperature of 53°C (soldering point temperature of 35°C) would have a projected L70 lifetime value...
