FOLDED OPTICAL SYSTEMS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18338658 titled 'FOLDED OPTICAL SYSTEMS
Simplified Explanation
The patent application describes a single fold optical system that includes a power prism and a lens stack with multiple refractive lens elements. This system allows for a long mechanical back focus without increasing the overall height of the optical system. By providing power on the prism, the total length and the horizontal length of the optical system can be reduced compared to conventional double folded optical systems with similar characteristics. Additionally, the optical system may include an anamorphic lens that corrects for astigmatism caused by surface errors on the prism's reflective surface.

Original Abstract Submitted
Single fold optical systems that include a power prism and a lens stack including two or more refractive lens elements. The single fold optical system may provide a long mechanical back focus without increasing the Z-height of the optical system. Providing power on the prism may reduce the optical total length and reduce the X-length of the optical system. The single folded optical systems may provide reduced Z-axis height and reduced X-axis length when compared to conventional double folded optical systems with similar optical characteristics. In addition, the optical systems may include an anamorphic lens that is oriented to correct for astigmatism caused by surface errors of the reflective surface of the prism.
