| [* black] Let's take a deeper dive into the projector and waveguide optics. | |
| - | [* black] Moving in for a close-up of the entrance gratings, we can see that they are on six different levels corresponding to the six layers of waveguides (red, green, and blue, on two separate focus planes). |

| + | [* black] ''Why six layers?'' This allows a separate waveguide for each color channel (red, green, and blue) on two distinct focal planes. |
| + | [* black] The three-waveguide-per-plane design corrects for the different refractive indices of each color. Without color-specific waveguides, [https://en.wikipedia.org/wiki/Chromatic_aberration|each color would focus to a slightly different point|new_window=true] and deform the image. |
| [* black] Figure 6 is taken from the Magic Leap patent application [https://patents.google.com/patent/US20160327789A1/en|2016/0327789|new_window=true] and shines some light on the optics' inner workings. | |
| [* black] For your edification and delight, we've included our own explanatory diagram, complete with cats. |
