OPT-RIU series Diffuse Front Ring Lights 

OPT-RIU Series – Diffuse Front Ring Lights (Standard Light Source)

The OPT-RIU series from OPT includes high-quality diffuse front ring lights specifically developed for demanding industrial machine vision and inspection tasks. These ring lights use a special diffuser that effectively reduces unwanted reflections on complex-shaped objects and ensures uniform, shadow-free front illumination—an essential advantage for highly reflective surfaces.

Thanks to this diffuse front illumination, even the finest details, patterns, and contours become visible without unwanted glare or reflections. Therefore, OPT-RIU ring lights are particularly suitable for inspecting markings and patterns on reflective surfaces, inspecting electronic components and glass products, and quality control of stamped and injection-molded parts.

The series is available in various diameters and light colors and can be flexibly integrated into automated vision systems. The homogeneous light distribution ensures stable image processing results and helps camera systems maximize contrast and detail visibility.
