LEDCHECK™ II and LEDCHECK™ VIII are a modular assembly designed specifically for color testing light emitting diodes on printed circuit boards under test on automatic test Equipment.

We can also work with alternative LED Testing hardware products for your fixture requirements.
Each module can accommodate 2 or 8 LED’s and modules can easily be cascaded should the need for additional channels arise.
Each channel measures 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. Using digital channel addressing, the channel selection is also under control of the test system.
While the color measurement system has good wavelength accuracy designed in, various factors influence the true accuracy of the measurement. The treatment of the fibers, peak versus dominant wavelength of the LED with clear, tinted, or diffused lens and temperature influence the measurement of color.
The LEDCHECK color test module is not a spectrometer, but rather an inexpensive multi-channel color-measuring device with excellent repeatability. Once the hardware and measurement are setup, LEDCHECK can be relied upon to perform the color tests within the prescribed criteria.
