UV LEDs from Bivar gain traction with applications traditionally targeted for fluorescent UV lights

There are many industrial applications ideally suited for, and already embracing, ultraviolet (UV) LEDs including counterfeit currency detection, fingerprint identification, fluorescent ink, and leak detectors.

Bivar’s unique differentiation is in its proprietary manufacturing process, which enables its UV LEDs to maintain their radian power at the specified wavelength much longer than previous versions and competitive offerings. With a tight tolerance of +/- 2.5nm, compared to alternative solutions with a tolerance of +/- 5nm or wider range, Bivar UV LEDs experience less degradation and therefore, optimal product performance. In addition to tight tolerance, Bivar has enhanced the encapsulation process to improve overall product performance. 
         
Bivar’s UV LED product family is available in 3mm (UV3TZ) and 5mm (UV5TZ) through hole packages, each comprised of four tightly binned wavelengths, 390, 395, 400, and 405 with a wavelength tolerance of +/- 2.5nm. The UVTZ series provides 10-20 mW output while consuming only 15ma of current and has a rated operational life of 10,000 hours compared to 1,000 – 2,000 hours in alternative solutions. Both packages are available with a narrow 15 degree and slightly wider 30 degree viewing angle. Each LED contains an integrated Zener diode to provide enhanced ESD protection. All Bivar UV LED devices demonstrate high resistance to shock and vibration versus traditional filament based light sources. Like all Bivar LEDs, the UVTZ series is RoHS compliant.
