Crystal IS launches Optan SMD UVC LED for sensor and instrumentation makers

Crystal IS Inc of Green Island, NY, USA, an Asahi Kasei company that makes proprietary ultraviolet light-emitting diodes (UVC LEDs) grown pseudomorphically (strained) on aluminum nitride (AlN) substrates, has launched its latest Optan UVC LED product. Operating from a maximum drive current of 300mA in continuous mode, the Optan SMD (surface-mount device) UVC LED emits at wavelengths of 260-275nm over a wide viewing angle of 100° with light output of more than 2mW. The typical L50 life-time is 3000 hours at 100mA.

Targeted at manufacturers of sensors and instrumentation in ocean and industrial process applications (for which performance and reliablity are critical), the Optan SMD is a long-life solution with low power consumption, giving users an increase in intervals for instrument maintanence.

Optan SMD is environmentally friendly, which is essential for the control of damage from bacteria and biofilms (which has a wide-ranging impact across industries that is estimated to cost several hundred billion dollars annually). However, solutions available currently are either not completely effective or being phased out due to toxicity concerns. "Our customers came to us with a difficult situation in controlling biofouling, where coatings, traditional UV lamps or mechanical wipers weren't that effective," says CEO Larry Felton. "Our latest Optan product will solve that problem, especially when it comes to ocean and industrial process instrumentation." Crystal IS says that the Optan SMD enables more effective and efficient biofilm and biofouling control.

The Optan SMD also supports total organic carbon (TOC) monitoring in water (since high levels of TOC can degrade industrial water purification systems, reducing semiconductor yields, contaminating pharmaceutical batches and damaging power and steam generation equipment).

In addition, the Optan SMD can be used as a low-voltage source of UVC light for the calibration of cameras, photodetectors, etc.

Samples of the Optan SMD are available now.
