The primary purpose of a machine vision lighting system is to identify features of interest in a target material. Once this data has been collected, the system will use the information to sort or grade material or determine whether defects are present.<\/p>\n

Obtaining a good image is critical to the performance of a machine vision system and a better image can result in faster processing times, faster line speed and higher-quality products. When optimizing your machine vision lighting for your application, you\u2019ll need to consider: wavelength, uniformity, angle of illumination and intensity. This post will outline these considerations.<\/p>\n

Wavelength<\/h3>\n

To maximize system performance, selecting the most appropriate wavelength will ensure that the features of interest are enhanced. The optimal wavelength for a specific application will be determined by the optical properties of the target material and the features of interest as well as the spectral response of the camera. Learn more about Wavelength in Machine Vision Lighting in this post.<\/a><\/p>\n

Uniformity<\/h3>\n

Non-uniformity in machine vision lighting will result in poor image quality and an unclear signal to the system. With non-uniform lights, the system software may struggle to differentiate between features of interest and non-uniformities caused by the lighting.<\/p>\n

Angle of Illumination<\/h3>\n

In a machine vision application, the target object\u2019s shape, surface structure, and material type will all influence the way light is reflected. In each application, the correct angle of illumination must be selected to obtain a high-quality image. Front lighting and backlighting are the most common configurations.<\/p>\n

Intensity<\/h3>\n

Having achieved good contrast in the image, higher intensities allow for a reduced camera capture time which in turn leads to higher run speeds. ProPhotonix utilizes a high density LED packaging method called Chip-on-Board<\/a> LED technology. The high-density arrays built using this technology result in an extremely uniform, high-intensity light. This technology offers a number of other advantages in machine vision lighting applications.
