INDUSTRIAL LIGHT SOURCE

Bar Light

A bar light is a linear LED array positioned at an angle to the surface. This oblique incidence makes height differences — embossing, scratches, engraving — cast shadows and stand out. It can be used alone as dark field illumination or in opposing pairs; on long parts, several bars are placed side by side to cover a wide area.

• Surface defect and scratch detection
• Reading embossed or engraved characters
• Wide-area illumination over conveyors
• Dark field applications
