A functional element (10) is arranged at the intermediate focus. The functional element has a thickness of more than 0.5 millimeter. A solid body consists of polymethyl, polystyrene, polyethylene, polycarbonate, glass, acrylic resin or a polyester resin. USE - Limiting device for use in optical device (Claimed), for limiting the transmitted optical power. ADVANTAGE - The limiting device has a focusing lens, which bundles incoming light on an intermediate focus, where a functional element is arranged at the intermediate focus, and thus enables to limit the transmitted optical power uniformly.de620670utility model202010002568
