In machine vision systems, the primary function of a light source is to project light onto the object under test in an appropriate manner, highlighting the contrast of the features being measured. A good light source can improve the overall system resolution and reduce the burden on subsequent image processing.
In visual inspection systems, commonly used light source types mainly include ring lights, bar lights, backlights, coaxial lights, diffuse dome lights, and point lights. Among them, machine vision ring lights are placed coaxially with the CCD lens and are generally aligned with the edge of the lens.
The advantage of a ring light source is that it can be directly mounted on the lens, and when the distance to the object being tested is appropriate, it can greatly reduce shadows, improve contrast, and achieve large-area fluorescent illumination. Ring light sources are excellent for detecting defects on highly reflective material surfaces and are very suitable for defect detection in products such as circuit boards and BGA (Ball Grid Array) packages.
AFTvision specializes in the research and development of LED lighting for industrial inspection and dedicated light sources for machine vision. Their ring light sources offer different illumination angles and color combinations, enhancing the three-dimensional information of objects. High-density LED arrays provide high brightness, and various compact designs save installation space and solve the problem of shadows from diagonal illumination.
Features:
Adjustable brightness, stable performance, ultra-long lifespan, high-brightness LEDs produce 360-degree shadowless illumination, widely applicable, and can be selected according to different lenses.
Application areas:
Inspection of components on printed circuit boards, inspection of stains on plastic caps, label inspection, PCB board inspection, IC component inspection, microscope illumination, LCD calibration, plastic container inspection, circuit board illumination, chip and workpiece inspection, substrate and printing plate positioning, etc.
The AFT-RL series ring light source is a high-brightness LED light source designed specifically for machine vision, industrial inspection, and industrial stereomicroscopy. It features adjustable brightness, low temperature, uniform illumination, flicker-free operation, and no shadows. Its unique embedded structure allows users to add polarizers as needed to reduce light interference and significantly improve image quality.
