Description
LL158 Line Lights Deliver Directional Contrast Illumination
The LL158 Line Lights are engineered specifically for oblique illumination applications in machine vision systems. Unlike standard line scan lighting, the LL158 introduces a unique 30 degree angle of incidence within the plane of the light housing. This specialized lighting geometry enhances contrast on surface features that run parallel to the inspection direction, making it highly effective for detecting scratches, streaks, and subtle surface variations.
This capability is especially valuable in industrial environments where continuous quality monitoring is required. By emphasizing directional defects that may otherwise go unnoticed under conventional lighting, the LL158 improves inspection accuracy and supports more reliable quality control processes.
Improve Surface Defect Detection
The LL158 Line Lights are particularly effective in applications involving sheet metal inspection, continuous feed conveyor systems, and other production environments where surface defects must be detected in real time. The oblique lighting angle enhances visibility of fine imperfections, allowing machine vision systems to capture high contrast images with greater clarity.
This makes the LL158 ideal for industries such as automotive manufacturing, metal processing, packaging, and precision material handling. Its ability to reveal subtle surface anomalies helps reduce product defects and improves overall production quality.
Offer Flexible Length and Wavelength Options
The LL158 Series is available in lengths ranging from 6 inches to 90 inches in 6 inch increments, providing excellent flexibility for integration into a wide range of inspection systems. This scalability allows engineers to match the lighting system precisely to their production line requirements.
The series also offers multiple visible wavelength options, including 470 nm blue, 530 nm green, 625 nm red, and white light. These wavelength choices enable users to optimize contrast based on material type and inspection goals, ensuring maximum visibility of surface features.
Built on the same housing platform as the LL137 and LL167 Series, the LL158 integrates easily into existing system designs while offering specialized oblique lighting performance.
Enhance Machine Vision Performance
The LL158 Line Lights are designed to improve inspection accuracy in applications where directional surface defects are critical. By using a 30 degree angled illumination approach, the system enhances the visibility of features that standard line lights may fail to detect.
This makes the LL158 particularly effective in continuous production environments where speed and accuracy are essential. Its consistent illumination performance helps reduce inspection errors and improves overall process efficiency.
