Fringe Projector Unit
AssemblyA blue-LED light engine and DMD chip that projects a timed sequence of sinusoidal fringe patterns onto the part. Blue light at 460 nm narrows ambient-light interference and gives sharp edges on dark or reflective surfaces. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
