Throughout the industry, it is widely accepted that an estimated 4% error currently exists with most LED light measurements. This 4% error is responsible for a massive loss in revenue across the industry as manufacturers and laboratories undervalue their own LEDs or send out product that does not perform as expected. Much of this 4% error traces back directly to the current source and methods being used during testing. To reduce the error and improve LED light measurements, Vektrex introduces the Performance Current Source Series. These high performance current sources are the only current sources that employ precise, accurate pulsing with microsecond rise times and low-jitter triggering. The resulting ideal current waveforms reduce uncertainty and enable accurate LED measurements with excellent measurement repeatability.
