When compared to structured laser light sources, LED technology ensures more homogeneous illumination in addition to sharp edges and no speckle effect. Many 3D machine vision applications require structured light to be projected onto inclined surfaces, i.e. at a certain angle from the vertical axis. In such cases, the focus is maintained only within a small area close to the center of the field of view and the rest of the image shows relevant defocusing thus making 3D measurement inaccurate.

For this reason, our Laserglow’s Structured LED Light sources will be equipped with a high-precision tilting mechanism so that the projected light is properly and evenly focused across the entire sample surface.
