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.

 • Is there a minimum order quantity?  Can we buy 1 pcs as MP?
     For MP shipping of Optan, Minimum Order Quantity is 10pcs.
     For samples, Minimum Order Quantity is 1pcs.

 • 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.
