Abstract
A current challenge for VR headsets producers is to reduce the weight and size of headsets. One very promising approach is the use of pancake lenses that help reducing the weight of the VR lens system but at the same time significantly increase the optical quality. Due to their complexity pancake lenses confront manufacturers with many challenges in testing and fabrication. TRIOPTICS´ expertise in active alignment and optical metrology enable our customers to create better pancake lenses for the challenges of tomorrow.
