Test Assembly Snoops Out LED Color

The LEDCHECK VIII assembly automatically tests the color, wavelength, and light intensity, including WHITE color, of LEDs on printed-circuit boards. The modular assembly accommodates eight LEDs and modules can be cascaded easily should the need arise for additional channels. Each channel measures the true color of the LED under test and provides an analog output to the test system proportional to the wavelength of the light detected from the LED. Via digital channel addressing, the channel selection is also under control of the test system. Everett Charles Technologies, Pomona, CA. (909) 625-5551.
