The discussion revolves around the properties of lens design, specifically focusing on the radii of curvature (R1 and R2) of the two spherical surfaces that form a lens. Participants are questioning whether these radii must be the same or can differ, and what implications this has for the lens's symmetry and functionality.
The discussion is active, with participants sharing their thoughts on symmetry and its relevance to lens design. There is a recognition that the radii can be different, but the implications of this difference are still being examined. Guidance has been offered through references to external resources.
Participants are navigating assumptions about lens symmetry and its impact on optical properties. There is an acknowledgment of differing perspectives on the necessity of equal radii in lens construction.
Why would you see symmetry as being important, in a lens? How could you go about determining what would be the effect if the radii were not identical?I hope that they are same, otherwise there won't be symmetry.
