When specifying LED lighting for machine vision applications, the LED wavelength can have a significant impact on the success of the vision inspection.  When utilizing white LEDs, it’s important to understand that the radiated emissions are a combination of most of the wavelengths from the visible spectrum; for white LEDs, the color temperatures range from the warm, yellowish end of the spectrum to the cool bluish end and may ultimately impact the accuracy and robustness of your inspection.  For this reason, it’s important to understand the concept of color temperature: how it’s measured, its impact on the success of your vision system, and how to ensure you source the best white LED light for your application.
