Optical Design Assignment 3

1. Given a set of ZEMAX OPD fans (on-axis), use MATLAB to fit sets of Taylor, Zernike, and Chebyshev polynomials

2. Design an apochromatic lens (thin-lens triplet) f/8, focal length 50 mm, with zero fourth-order spherical aberration and the same focus for the three wavelengths (d, F, C). Your choice of glasses. Include a list of the Seidel aberrations and a plot of chromatic focal length in your report.

   The following lenses should be f/5.6 with a focal length of 50 mm and half field-of-view of of 24°. Optimize over three fields (0, 16, and 24 degrees) and three wavelengths (d, F, C). Use two Schott preferred glasses in these designs.

3. Design a rapid rectilinear lens. You choose whether the flint or the crown should be first. Use pickups to keep the doublets symmetric. Vary the air-spacings between the lenses and the stop.

4. Design a Petzval lens (see Kidger p 183-185) starting with two fraunhoffer cemented doublets about a central stop. The Petzval lens may be derived from the rapid-rectilinear by removing the requirement for perfect symmetry between the two separated doublet elements.

For each lens, provide the ZEMAX data file and

1. a full listing of lens data
2. a drawing of the lens
3. rms spot size vs. field
4. ray fans
5. field plot
6. spot diagrams.
