28.  Modeling: Sweatt model; other approximate techniques; rigorous techniques.

29.  Applications: achromatization; lenslet arrays; beam shaping.

Grading and Exams:

The final grades will be based on the course distribution of all the graded work and weighted as follows:

                        Homework                  20%

                        Midterm – In Class      35%

                        Final Exam                  45%

We believe that this serves to give the students the fundamental expectation of what their grade will be based on, but it also provides the necessary digression to the instructor to adjust grade lines as needed based on the course distribution which is not known until after final exams.
