The coronavirus pandemic has disrupted key parts of Apple’s business, but it hasn’t derailed the company’s plans to build what could be its next important technology platform—augmented reality devices.

The Information has learned that Apple is working with Taiwan’s Foxconn Technology, Apple’s largest contract manufacturer and the one responsible for building most iPhones, to develop semitransparent lenses for its AR devices. As of two months ago, the lenses—considered one of the most essential elements of the head-worn devices—had passed the prototype stage and entered trial production, a person familiar with the matter said.
