Light from the vertically-arranged LEDs is transmitted through the light-guiding diffusion plate and uniform diffused light is illuminated centrally on the workpiece from a low angle.
Diffuse LED dark field illumination
The rectangular FPQ3 series delivers a very diffuse light output with no LED reflections of the component being imaged.
Depending on the application and the object, these lights can be used at extremely short (approx. 30 mm) through to extremely long (approx. 200-250 mm) working distances. At the short working distances they can be used to highlight and image characters and scratches in a dark field. At the longer working distances they can be used to uniformly image the entire workpiece in a bright field.
The low-angle square lights are ideal for imaging square shaped workpiece. Uneven illumination which may occur with the use of the low-angle ring light can be avoided. It can detect the outline of corners and prevents glare, which is difficult with ring lights.
