[* black] A cast magnesium block holds all the optics and sensors, and is surprisingly hefty for an HMD. Other [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 thermal paste to help dissipate the IR rangefinder's heat.
[* black] Metal also offers a stiffer mounting place to keep the cameras stable and focused after their rigorous calibration.
- [* black] Luckily there's also some black silicon-like adhesive that will allow for some flexing to protect the cameras from drop damage.
+ [* 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.
