Goals and “Not Goals” ? Goals: – Brief overview of basic imaging concepts – Introduce some lingo of lens designers – Provide resources for quick reference or further study ? Not Goals: – Derivation of equations – Explain all there is to know about optical design – Explain how CODE V works Introduction to CODE V Training, Fall 2022, Slide 1?? Sign Conventions ? Distances: positive to right ? Curvatures: positive if center of curvature lies to right of vertex ? Angles: positive measured counterclockwise ? Heights: positive above the axis t 0 t 0 V C c = 1/r 0 V C c = 1/r 0 q 0 q 0 Introduction to CODE V Training, Fall 2022, Slide 1?? Light from Physics 102 ? Light travels in straight lines (homogeneous media) ? Snell’s Law: n sin q = n’ sin q’ ? Paraxial approximation: – Small angles: sin q~ tan q ~ q。 and cos q ~ 1 – Optical surfaces represented by tangent plane at vertex ? ignore sag in puting ray height ? thickness is always center thickness – Power of a spherical refracting surface: 1/f = f = (n’n)*c – Useful for tracing rays quickly and developing aberration theory Introduction to CODE V Training, Fall 2022, Slide 1?? Cardinal Points ? 6 import
