LENSES AND OPTICS
GoboXtreme Dark Blanks
27 March 2008
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.
