A highly reflective surface faces the lamp, transmitting light only where coating has been removed to reveal the gobo image pattern. Facing the lens, a highly absorbent multi-layer coating absorbs incidental light to maximize contrast and prevent image ghosting. An enhanced version is available to provide maximum optical performance, say Oerlikon: "The increased output and demanding thermal management of today's luminaires are putting gobos to the test. Our goal is to support OEMs and third-party gobo imaging firms by providing the highest performance gobo blanks that fit existing imaging processes," says Guglielmo Cappellari, product line manager for Oerlikon Optics.
