Matt Pinter, Smart Vision LightsIlluminating a product to attain the best contrast available is important in machine vision applications: the higher the contrast, the greater the difference between the background and the features to be inspected. Using the correct wavelength of light, proper lighting configurations and appropriate filters can increase contrast and result in more efficient image processing and faster inspection speeds. Making the right choices is application-dependent. Thankfully, guidelines do exist to help systems integrators choose the correct illumination sources for any particular application. The...Read full articleRelated content from Photonics MediaARTICLESMultispectral Lighting: A Practical Option for Difficult Industrial Imaging SituationsDuring the past few years, color and spectral imaging approaches have become more prevalent in machine vision system design.
