→Table of ray transfer matrices: The matrix for reflection from a flat mirror had a -1 in the D spot, it should 1. This follows all conventions, and makes it consistent with the curved mirror matrices. Tags: Manual revert Mobile edit Mobile web edit |
→Table of ray transfer matrices: I updated the text describing the reflection from a flat mirror. The original said it was only valid for perpendicular interactions, but its valid for all angles Tags: Mobile edit Mobile web edit |

| Valid for flat mirrors oriented at any angle to the incoming beam. Both the ray and the optic axis are reflected equally, so there is no net change in slope or position.
