Taking Apart The Oculus Rift
I know many of you are eagerly awaiting your new Oculus Rift and when it arrives will be treated as your first born. However, not everyone thinks like that, especially those over at iFixit.
iFixit take apart anything and everything to figure out how it works so if you need to, you can make a stab at a repair. Thinking about what I just said, I'm hoping a nuclear reactor may be off limits.
Once the folks at iFixit cracked open the Oculus VR headset, iFixit discovered a custom display, along with special lenses to make the Oculus more comfortable. They are no longer just simply round lenses as can be found on the DK2. The lenses in the Oculus Rift are known as "Fresnel lenses.” Fresnel lenses use thin arrays of concentric prisms, achieving a large viewing angle and short focal length with far less material than traditional curved lenses. However, unlike a typical Fresnel lens, the lenses on the Oculus include a sloping layer on their backsides, allowing the rift to be lighter than say the DK2. Additionally, the user can adjust focus simply by moving the headset closer or further away from the face.
The consumer Oculus Rift contain dual custom OLED displays, no longer Samsung Note 3 screens but custom made for VR. Each display has a resolution of 1080-by-1200 and measures 90 mm diagonally, for a density of 456 pixels per inch. That’s more than an iPhone 6s Plus (456 ppi) which would be viewed from at least 8 inches away for individual pixels to be indiscernible. Pixels in the Oculus Rift are certainly still visible but far reduced over the DK2.
iFixit noted certain parts of the Oculus Rift are reasonably easy to replace, such as the built-in headphones and face pad. The other parts are far less serviceable.
