9. NOTE: R>0 if the REFRACTED beam through that surface is on the SAME SIDE as the radius of curvature for that surface. R<0 if the REFRACTED beam through that surface is on the OPPOSITE side of the radius of curvature for that surface

10. Table 5.2 Sign conventions for lens formulas INCOMING light to optic defines the POSITIVE side for sign convention for S o OUTGOING light from optic defines the POSITIVE side for sign convention of S i f>0 represents a CONVERGING lens f<0 represents a DIVERGING lens

15. Inversion with Mirrors

16. The ‘thin lens’ limit of ray tracing is only on simple way of analyzing a system of optical components. Phys 418 – Imaging covers ‘thick lenses’, a matrix approach to ray tracing, and computerized ray tracing.
