| [* black] A cast magnesium block holds all the optics and sensors, and is surprisingly hefty for an HMD. The [guide|106064|VR|new_window=true] [guide|60612|headsets|new_window=true] we've taken apart all used lightweight plastic. | |
| [* black] But metal makes a better heat sink, and the electronics and IR illumination (likely [https://en.wikipedia.org/wiki/Vertical-cavity_surface-emitting_laser|VCSEL|new_window=true] devices) all produce heat. | |

| + | [* black] That pink stuff is a thermal pad to help transfer the IR rangefinder's heat into the aluminum frame. |
| [* black] Metal also offers a stiffer mounting place to keep the optics stable and focused after their rigorous calibration. | |
| [* black] But stiff isn't always best—some of these components are mounted with foam adhesive, which will be more forgiving as things flex when heated. |
