Identifying the correct lighting technique to use within an inspection task is vital to the success of the solution. The light (photons) that is being reflected from the scene is ‘captured’ by the camera and forms the image which is at the heart of many computer vision or machine vision applications. This image is typically processed for inspection or monitoring purposes. This processing will struggle to provide correct data and robust results if the image is not illuminated consistently and appropriately.
In addition to the lighting, selecting the correct lens for optimum image quality for your application is where Multipix Imaging can help. Lenses can have considerably different characteristics that will impact the final image as well as the suitability for the environment they are being used in. It may be a very short working distance or very high vibrations that need to be considered, not just the more obvious characteristics of format size and mount-type.
Current Controlled – sophisticated sensing technology to ensure each LED unit is supplied the correct current. Reduces heat generation to improve output intensity, efficiency and stability
Voltage Controlled – typically driven by industrial 24/12V DC power supplies. Over-driving (strobing) is possible for instantaneous, high intensity illumination.
Multipix Imaging provide and offer advise on imaging accessories including an excellent range of filters from MidOpt. MidOpt filters with their unique StableEdge Technology make them the number one choice – specifically designed to be less susceptible to effects from angular shifting seen when optical filters are placed in front of short focal length (<12mm) camera lenses.
