Backlights

Effilux backlights are positioned behind the object to create high-contrast silhouettes, enabling precise edge detection and dimensional measurement. They provide highly uniform and diffuse illumination, minimizing reflections from the object surface. Commonly used for gauging, shape analysis, and presence/absence detection.

1. EFFI-BL

Uniform, large-format industrial backlight

The EFFI-BL is a large-area LED backlight designed to deliver powerful and highly uniform illumination, ideal for silhouette-based inspection tasks. It provides optimal contrast for detecting object contours, shapes, holes, and morphological features in machine vision applications.

With a homogeneity greater than 80%, the EFFI-BL ensures consistent lighting across the entire surface. Its anti-reflection system minimizes interference from surrounding light sources, enhancing image clarity. The integrated AIC driver allows precise control of light intensity, and the product can be easily customized to meet specific dimensional or optical requirements.

3. EFFI-SBL

Compact industrial backlight

The EFFI-SBL is a space-saving LED backlight designed for machine vision applications where installation depth is limited. With a thickness of just 15 mm and ultra-thin borders, it maximizes the illuminated area while minimizing footprint.

Its high uniformity—over 90%—combined with an anti-reflection coating ensures excellent contrast without hotspots, making it ideal for presence detection, dimensional measurement, and positioning tasks. The EFFI-SBL is IP67-rated for protection against water and dust, and available in a wide range of standard sizes from 25 mm to 200 mm. It features a dimmable integrated driver (built-in or in-cable), standard M12 connector, and supports white, red, or infrared (850 nm) wavelengths. Custom mechanical, optical, or electronic configurations are also available to meet specific needs.
