GoboExtreme™ Dark

High Performance Blanks for Gobo Imaging

Materion Balzers Optics’ GoboExtreme™ Dark is a high performance glass black & white gobo blank that provides extended thermal stability and lifetime compared to conventional gobos. The high performance double coated design combines both:

  • a “white side”: highly reflective aluminum mirror that faces the lamp, transmitting light only where coating is removed to reveal the gobo image pattern, and
  • a “black side”: highly absorbing multi-layer coating that faces the lens and absorbs incident light to maximize contrast and prevent image ghosting.

Designs are available to support multiple imaging processes including laser ablation and chemical etching.
