Backlights create contrast against a bright background to produce uniform illumination and minimize reflections of the object. They are commonly used to measure objects, or verify the presence or absence of holes or gaps in objects. Effilux LED Backlights are ideal for numerous machine vision applications such as pick-and-place, inspection of transparent and translucent materials like glass and fabric, and verifying fluid fill-level in bottles. Effilux's selection of backlights includes a backlight in a compact bar, and waterproof LED backlights with IP67 or IP69K protection.
