Apple’s VR headset may weigh less than an iPhone

Apple is reportedly planning to adopt a hybrid Fresnel lens design for its mixed reality headset to improve optical performance.

Apple has been working on a virtual reality (VR) headset for some time now. Rumours are rife about the device as the insiders have been trying to find out any leads on what consumers can expect. Now, the latest report from analyst Ming-Chi Kuo offers new insights on the VR headset. Apple is reportedly planning to adopt a hybrid Fresnel lens design for its mixed reality headset to improve optical performance in addition to delivering a broad field of view and to keep the weight of the headset under 150 grams. Most virtual reality headsets use Fresnel lenses, first invented some 200 years ago to focus lighthouse beams, to enable ultra-short focal lengths, but that these headsets typically weigh 300-400 grams or more with bulky form factors, reports MacRumors.
