VERS 50203 173 2006 MODE SEQ NAME RGB Ex 2. A Mangin mirror. NOTE 0 RGB Example 2. A Mangin mirror. A back-surface mirror. NOTE 4 NOTE 0 Sequential ray tracing. All the curves are negative. The thickness and the front curve radius that the rays pass through twice are in the data twice, as this is sequential ray tracing. z is to th NOTE 0 e right as usual, so the glass thickness is negative on the second pass as it is measured in the minus z direction. The thickness following a mirror is filled with the same medium as the space preced NOTE 0 ing the mirror, so the glass type is specified once. I set the thickness, curvature and semi-diameter for the second pass using pickup solves from the first pass. Try a right-click on a p. The m NOTE 0 onochromatic aberrations are very small here but the ghost image is a problem (a later lecture). The Mangin mirror provides one of a number of methods that we shall eventually discuss for correcting NOTE 0 the aberrations of a concave mirror. (C) R. G.
