Providing design engineers with devices capable of uniform optical light patterns over an extended temperature range, TT electronics OPTEK Technology has developed a family of ultraviolet LEDs in the UV-A spectrum. Designated the OUE8A Series, the UV LEDs are offered in a variety of wavelengths and housed in hermetic TO-46 metal can packages.

“The OUE8A Series UV LEDs eliminate any environmental concerns associated with the disposal of traditional mercury UV lamps,” said Alan Bennett, vice president of sales for OPTEK Technology. “Not only do these devices allow customers to target specific applications with the narrow wavelength emission, but they are able to do so while eliminating any mercury hazard.”

The UV LEDs are ideal for medical and industrial applications including phototherapy treatment, dental applications, fluorescence and ultraviolet-visible spectroscopy; photo-catalyst curing of inks, coatings and adhesives; as well as paper currency and document validation. Additional applications for the OUE8A Series UV LEDs include aircraft coatings and biohazard detection equipment/systems, skin dermatology, forensics, and automotive oil, A/C, and fluid detection.

All of OPTEK’s UV LED devices have an 18º typical half power emission angle and a pulsed forward current of 1.6 A. Operating temperature ranges from -40ºC to +85ºC. The OUE8A Series UV LEDs are RoHS compliant and ESD protected for reliable operation.
