Oerlikon Optics has released its GoboXtreme Dark blanks to OEMs for imaging by laser ablation or chemical etch processes.
The high performance black and white blanks provide improved long-term temperature stability and extended lifetime compared to conventional gobos.
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 incident light to maximise contrast and prevent image ghosting. An enhanced version is available to provide maximum optical performance.
