Optical Design Assignment 5

  1. Design a 50-mm focal length f/5.6 double gauss lens with a half-field of view of 24°. Your merit function shoud use standard wavelengths and fractional fields of 0, 0.7, and 1.

  2. Re-design the lens for f/2.8 and a half-field of view of 35°.

  3. Design a 50-mm focal length f/1.4 double gauss lens with a half-field of view of 24°.

  4. Use MATLAB to generate images showing 0.5, 1, and 2 waves of aberration for W020 = r2, W040 = r4, astigmatism (line focus) = y2, astigmatism (mid focus) = x2 - y2, and coma = r2 y

    For each lens, provide

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

    Also generate MTF plots at all fields. Compare the MTF plots of the double-gauss to the corresponding triplet lens.
