Product Description

The FÖGE VL-BLL Bar Backlight for Linescan is purpose-built to deliver uniform silhouette illumination for line scan vision systems. Its linear LED array provides tight, consistent light along long fields of view, making it ideal for high-speed inspection of glass sheets, plastic film, extruded parts, and other elongated or continuous materials. By minimizing light gaps and offering robust performance across the full scanning width, VL-BLL enables accurate, high-resolution edge detection during fast-moving operations. With an industrial-grade housing, heat-resistant electronic design, and trigger compatibility, this light is easy to integrate and engineered for long-term reliability—even in demanding manufacturing environments.

Advantages

Enables precise, continuous inspection over long scanning areas
Reduces false readings with uniform, high-contrast illumination
Compact linear profile integrates easily into narrow vision setups
Maintains stability under extended operation and high temperature conditions
Triggerable for synchronized image capture in dynamic production lines
Improves accuracy of linescan inspections
Ensures crisp edge and silhouette detection across wide lengths
Simplifies setup and integration with robust, compact form factor
Supports high-speed and continuous operations
Delivers stable illumination with long service intervals
