STEMMER IMAGING USA brings forward a broad Metaphase LED illumination lineup that covers the most common lighting geometries used in industrial inspection, from silhouetting and diffuse dome lighting to line scan, ring, coaxial, and collimated solutions. The product families below highlight the primary illumination groups within the Metaphase range.
Backlights
For silhouette-driven inspection and transmissive measurement, Metaphase backlights deliver the intensity and uniformity needed to produce clean, repeatable edges. The lineup includes low-profile platforms that integrate easily into compact stations, ultra-thin formats for tight mechanical clearances, collimated tube styles that sharpen outlines by controlling stray light, and SWIR-capable variants that extend visibility for use cases like fill-level checks and imaging through challenging containers.
Bar Lights
Built to flood a target with consistent illumination across a broad area, Metaphase bar light families scale easily from single-station builds to standardized multi-cell deployments. Options range from high-output multi-row designs to configurable series with lens, polarizer, and wavelength choices, plus IP-rated constructions suited to harsher environments. For sanitation-driven facilities, washdown-ready bar lights add rugged materials and high ingress protection to maintain performance through repeated cleaning cycles.
Coaxial Lights
When reflections, glare, or shadowing complicate surface inspection, Metaphase coaxial lighting families provide controlled illumination aligned to the camera axis for cleaner, more consistent imaging. This group includes diffused axial solutions that use beam-splitter technology for homogeneous coaxial output, as well as hybrid coaxial-dome configurations that help fill the void created by dome camera ports, improving coverage on reflective or appearance-sensitive targets.
Dome and Diffuse Area Illumination
To reduce hotspots and present surfaces with a softer, more uniform look, Metaphase dome and diffuse area lights are designed to surround the target in even illumination. The range spans scalable dome formats with multiple size and port options, compact and high-power diffused tube styles tailored for specular or curved materials, flat dome platforms engineered for stable continuous output or responsive strobing, and SWIR variants that help reveal contrast where visible diffusion falls short.
Line Lights and Line Scan
Optimized for continuous motion and high-speed imaging, Metaphase line scan illumination families emphasize long-run uniformity, high intensity, and dependable thermal behavior. The portfolio includes ultra-bright line lights with adjustable optics and cooling options, high-uniformity back line lights for web inspection and measurement, dark field and oblique line lights that elevate texture and defect visibility, collimated line lights for longer working distances, and SWIR line scan solutions for applications that demand non-visible contrast.
Ring Lights
For compact stations that benefit from camera-centered illumination, Metaphase ring light families deliver repeatable lighting geometry with strong control over shadows and surface contrast. Near-axial designs prioritize shadow reduction and specular management, while off-axis configurations create low-angle illumination to highlight scratches, dents, and subtle surface defects. Washdown-ready versions add sealed protection for moisture and cleaning exposure, and flexible mounting platforms make it easier to standardize across different port sizes and cell layouts.
