A new folded optical system with an enhanced efficiency using two polarization‐selective cholesteric liquid crystal reflectors is proposed. In conventional pancake optics, the optical path length is tripled but its efficiency drops to 25%. Our new configuration provides 50% efficiency, while the optical path length is doubled.
