  • A cast magnesium block holds all the optics and sensors, and is surprisingly hefty for an HMD. The VR headsets we've taken apart all used lightweight plastic.

  • But metal makes a better heat sink, and the electronics and IR illumination (likely VCSEL devices) all produce heat.

  • That pink stuff is a thermal pad to help transfer the IR rangefinder's heat into the aluminum frame.

  • Metal also offers a stiffer mounting place to keep the optics stable and focused after their rigorous calibration.

  • 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.

Un bloque de magnesio fundido contiene todas las ópticas y sensores, y es sorprendentemente fuerte para un HMD. Los auriculares VR que hemos desmontado utilizan todos los plásticos ligeros usados.

Pero el metal hace un mejor disipador de calor, y la electrónica y la iluminación IR (probablemente dispositivos VCSEL) producen calor.

Ese material rosado es pasta térmica para ayudar a disipar el calor del telémetro IR.

El metal también ofrece un lugar de montaje más rígido para mantener la óptica estable y enfocada después de su calibración rigurosa.

Pero la rigidez no siempre es lo mejor: algunos de estos componentes están montados con espuma adhesiva, que será más tolerante a medida que las cosas se flexionan cuando se calientan.
