wenglor sensoric group Expands Its Illumination Technology Portfolio with New Ring Light and Dark Field Attachment

The wenglor LRL ring light is equipped with LEDs arranged in a circle that ensure uniform illumination intensity across the entire test object. With two sizes and three light colors, it is suitable for a wide range of applications and camera requirements in industrial image processing. The optional angle changers enable flexible adjustment of the illumination angle, allowing for better field of view homogeneity. In addition, the new ZMRG dark field attachment has been added to the illumination portfolio.

Available in two different sizes with an inner diameter of 37 and 76 mm respectively, the LRL ring light creates optimal lighting situations in confined spaces and compact applications, as well as for larger lenses and more demanding applications. Compatibility with angle changers allows for a bright, even and diffuse lighting solution with different beam angles without shading. The convergence light attachment minimizes ring effects. Six M4 mounting threads, extensive mounting accessories and the connection via a 5-pin M12 plug ensure flexible mounting options. The LRL ring light offers three different types of light with white, red and infrared light and is continuously dimmable. It can be used flexibly in continuous or strobe mode Overdrive. The robust, anodized aluminum housing with IP67 degree of protection guarantees efficient heat dissipation, ensuring constant and reliable light output even in continuous mode. The small LRL ring light can also be attached directly to C mount lenses using an adapter.

New Dark Field Illumination for Precise Surface Inspection
The LMFX dark field illumination combines the LMRX ring light with the new ZMRG dark field attachment to ensure precise surface inspection at a 60 degree angle of incidence. This configuration is particularly suitable for inspecting glossy and dark surfaces, where edges, bumps and scratches are clearly highlighted. For example, the LMFX dark field illumination helps with quality control and fault detection in electronics production by increasing the contrast at the edges of the individual components during PCB inspection, thereby improving their visibility.
