Optical Design Study 7

Tilts and Decenters

1. Take your triplet lens (from design study 2) and plot the total rss spot size (sqrt-sum-of-squares spot size for all fields) as a function of decenter (from 0 to 1 mm) and tilt (about x-axis) of the middle lens from zero to 5-degrees. Note that you should add fields for -y, +x, and -y (9-fields total) since the new system is not symmetric.

2. Now use your triplet lens as a 5:1 finite conjugate lens. Tilt the entire lens by 20-degrees about the x-axis. Vary the tilt of the image plane to locate the best image. Check the results against the Scheimflug condition.

3. Set up the KUTTER example from the textbook (p 199-202). Follow the "new axis" system. Note that the author is not using CODE V.

4. Layout a verify the operation of an Amici roof prism . Use non-sequential surfaces for the roof.
