SCR Scrolling Color Wheels

SCR Scrolling Color Wheels

Ocean Optics produces a variety of patterned SCR Scrolling Color Wheels using a proprietary Dichroic Filter Array™ (DFA) technology that delivers increased optical performance and better durability than traditional color-wheel technologies. With the DFA process, color wheels can be mass-produced with micron-scale precision patterning that yields brighter colors. Lightweight SCR Scrolling Color Wheels are available in a standard 33 mm and 98 mm sizes, as well as in custom designs.

About the Technology

Ocean Optics' DFA technology makes possible the microlithographic patterning of dichroic thin films onto optical and microelectronic substrates. The remarkable technique allows the patterning of an array of discrete dichroic filters to a size of 2 µm, with 1-µm spacing. This high-precision patterning can be applied to any filtering configuration the customer requests, and provides color filtering, spatial resolution, transmission efficiency and filter durability that's superior to dye-colored gels and other commonly used filtering technologies.

Key Features of SCR Scrolling Color Wheels

  • Patented precision-patterned coatings
  • Mass-production capabilities
  • Temperature and humidity stability for consistent color
  • High optical transmission efficiency for superior brightness
  • Improved durability for long life
  • Precision balancing for low noise
