Optical Stackup

Today I'd like to go over the optical stackup I'm using for the full digit. The materials from top to bottom are

  • Standard copy paper
  • Two pieces of 1/8-inch-thick acrylic opaque white, laser cut to form segments
  • One piece of 1/8-inch-thick 40% transparent white acrylic, laser cut to a size of 6.0 inches x 4.2 inches
  • A PCB with reverse mount LEDs for a smooth top

I ordered the plastics from TAP Plastics. The files for the laser cutter will be posted to github.
