Assignment 5
Read Smith, Sections 2.1-2.5.
- How do Smith's sign conventions differ from ours? Give
examples of how this affects his formulas.
- Do exercises 1-5 from chapter 2 in Smith.
- Using the lens description in Smith, page 506, do the following:
- find the back focal distance (BFD). Smith calls this BFL.
- find the principal planes and hiatus
- draw the lens using Matlab, showing the position of the principal
planes and the rear focal plane.
- Do problems 2-3 through 2-6 from the class notes (chapter 2).
- Do problem 2-9 from the class notes. Use either Matlab or
Excel.
- Consider a hemispherical lens of radius 7.5 cm and index 1.5, as shown below
- Find the axial distance d from the rear surface to the point of intersection on the axis
for rays entering parallel to the optical axis at heights of 3.5 cm and 0.1 cm.
- For the same lens, find the maximum height at which a parallel input ray can enter
without undergoing total internal reflection.
