In any machine vision system, the light source plays a vital role in determining the success or failure of the entire system. Light source is designed to avoid the disturbance of ambient lighting, reduce complexity of system design and improve the signal-to-noise of image to proceed to detection or inspection for any purpose. The light source is split into several types, like ring light source, bar light, point light and so on. The area light source can cast light from various angles, and it provides a wide range of colors, including red, green, blue, white and more. With its light beams being integrated and densely-distributed, the area light source provides intense   illuminations in an even manner. Common applications are measurement of mechanical parts, electronic components, cosmetic detection of IC.

Challenge

As there are all sorts of light source, it is significant to choose the correct ones. Several points require careful consideration while making a choice over light source, like working distance, field of view, illumination method, special requirement over installation, color, material and light source brightness. Thanks to its characteristic, the illuminance of light source is 20%-50% brighter than other peers. It is perfect to deal with product profile measuring, dimension measuring, defects of glass bottles, scratches of plastic objects.

Benefits

• Under a specific working distance, the light beams of great integrity can illuminate in an even manner.

• Low angle: it can clearly show the concave-convex of the object surface, so very suitable for defect detection of silicon wafer or base of glass, reading of mint-mark characters

• No shadow: cast vertical light with LED of high illuminance. Offerings of different colors, like red, green, blue, white and many more.
