LEDs for Disinfection: Klaran/Optan SMD


NEW Klaran
High Power UVC LEDs

Klaran (UVC LED)

Klaran™ UVC LEDs feature peak wavelength of 250 to 280 nm and world-leading germicidal output powers of 15 to 30 mW. Applications are expected to expand to include healthcare, home electronics, and various other fields where UVC disinfection of water, air, and surfaces had previously been impractical.
With increasing global awareness of environmental risks associated with the use of mercury, as exemplified by the Minamata Convention on Mercury adopted in October 2013, there has been a heightening need for a UV light source to replace mercury lamps that are currently used to disinfect drinking water, to produce ultrapure water for laboratory use, etc.

Optan SMD
UVC LEDs for biofilm prevention

Optan SMD1 (UVC LED)

Optan SMD offers superior light output, long lifetimes and low power consumption for applications in biofilm prevention and biofoul control. These surface mount devices are environmentally friendly and emit a spectrum optimized for DNA deactivation.

Peak wavelength range is 260-275nm and output light power is min 2.0mW.

Who’s Crystal IS?

Crystal IS, Inc., an Asahi Kasei company, is an innovative U.S.-based manufacturer of proprietary, high performance ultraviolet (UV) LEDs. Their products are well-suited for applications in purification and sterilization, including industrial and point-of –use (POU) water purification. Their deep UV LEDs are also used in scientific and industrial instruments to measure the purity of water, air, and biological samples.

The breakthrough performance of these LEDs is made possible by Crystal IS’ low defect destiny, single crystal aluminium nitride (AlN) substrates and their proprietary-technology for crystal growth and LED fabrication. This results in higher powers and longer lifetimes of Crystal IS deep UV LEDs.

• When will samples of Optan SMD be available?

Optan SMD samples are now available.


• What the difference between Optan SMD and LEDs for disinfection? 

Optan SMD is targeting biofouling control in scientific and industrial instruments. Damage resulting from bacteria and biofilms has wide ranging impact across industries by increasing operational and maintenance costs and reducing the accuracy of measurements.
Crystal IS SMD LEDs for disinfection are better suited for disinfection applications in healthcare and consumer point-of-use water. If you have questions about UVC LEDs for these applications, please contact us.


• Are there any safety considerations when working with UVC LEDs?

Yes. UVC light may be harmful to the eyes and skin, thus proper safety precautions must be taken to limit exposure. In addition, ESD should be considered when you handle our products.
