Ring Lights are used to provide even, radial illumination around an imaging lens for optical or imaging applications. Ring Lights are mounted around an imaging lens, directing light towards an examined object. Ring Lights produce uniform, directly positioned light that is ideal for reducing shadows or providing even illumination to non-reflective objects. Compact versions of standard Ring Lights are also available for smaller sized imaging lenses or for inspecting small objects.

Edmund Optics offers a wide selection of Ring Lights that produce brightfield as well as darkfield illumination. Brightfield illumination features direct or slightly angled light shone upon an examined object that is ideal for most standard illumination needs for non-reflective objects. Darkfield illumination is achieved by shining glancing illumination upon an object. Darkfield illumination shows surface inaccuracies, scratches, or other imperfections upon an examined object making it ideal for inspection or quality assurance applications.
