Improving Light Efficiency in Pancake Optical Modules: A Guide

The shift toward slim, lightweight VR headsets has made the Pancake optical module a critical component in modern display engineering. By folding the light path through multiple reflections, these modules eliminate the "shoebox" bulk of traditional lenses. However, the most significant technical problem with this design is the inherent light loss caused by multiple polarizing and reflective...
