Optical Design Assignment 4
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 Schott preferred
glasses in these designs.
- Design an air-spaced triplet lens (see Kidger p 199-204). Use
the same crown glass for the outer positive
lenses and a flint for the inner negative lens. The stop should be near or at the
middle lens. Keep the element thicknesses thin. They are not to be
used as variables. We are looking for the classic Cooke triplet
design.
- Try to find both solutions for the Cooke triplet.
- Design an inside-out triplet lens with the crown as the middle
element. How do the powers of the three lenses change for this
triplet?
For each lens, provide the ZEMAX data file and
- a full listing of lens data
- a drawing of the lens
- rms spot size vs. field
- focal length vs wavelength
- ray fans
- field plot
- spot diagrams.
