How to illuminate
If the product is shiny, it is important to prevent the light source from being reflected and shiny.
Let’s compare the inspection items below when the ring lights is attached to the lens and when it is attached near the object.
When the ring light is attached to the lens, the Light is applied from a high position, so the light source is reflected and the image is shiny.
When installed near an object, the light source is not reflected and a clear image can be taken because the light is applied from a low position.
In the case of inspection to detect uneven parts
For inspections that detect unevenness, shine light at an angle so that the unevenness rises.
Backlight
In dimensional angle inspection, it is important to capture the edges cleanly.
Ring light can blur the edges.
Transmissive light is recommended to capture the edges cleanly.
