Questions about Freeform Folded Optical System: 1. How does the freeform folded optical system differ from traditional lens systems? The freeform folded optical system utilizes prisms with optical power to fold the optical axis multiple times, allowing for long focal lengths without additional lens elements, unlike traditional systems. 2. What are the potential applications of the freeform folded optical system beyond telephoto lenses? The technology can be applied in surveillance systems, satellite imaging, medical devices, and any other optical system requiring long focal lengths and compact design.
Original Abstract Submitted
a freeform folded optical system that include two freeform prisms with optical power. at least one of the freeform prisms is configured to fold the optical axis twice. thus, embodiments of the freeform folded optical system fold the optical axis three or four times. folding the optical axis three or four times in the freeform prisms allows for long focal lengths required for telephoto lens applications without requiring additional lens elements between the prisms. in addition, the configuration of the freeform folded optical system provides reduced z-axis height when compared to conventional folded lens systems with similar optical characteristics.
