Geometrical & Instrumental Optics II (1 unit). Measuring refractive indices, dispersing and deviating prisms, thin lenses, thick lenses, aberration evaluation, Keplerian and Galileo telescopes and compound microscopes. This lab is designed to complement the major topics discussed in Opti 202R, and it is recommended that these two courses be taken concurrently.

Course Objectives and Expected Learning Outcomes:
Upon successful completion of this course, each student should:
  • be able to apply the optical principles discussed in OPTI 202R.
  • be able to clearly and accurately summarize and communicate experimental procedures and results.
  • be familiar with basic data handling and analysis.
  • learn common optical methods and procedures that are routinely used in the optics industry.
  • understand the safe and proper handling of basic optical equipment.
Grading:
Weekly Lab Summary 75%
Final Analysis 20%
Unannounced quizzes 5%
Attendance Policy:
It is important to attend all lab recitation sessions, as what is discussed provides the theoretical and experimental background for the next lab. If you must be absent, it is your responsibility to obtain and review the information you missed. Unannounced quizzes will be given to encourage attendance, and to help you gauge your progress in learning the material.

Attendance for all of your scheduled lab sessions is mandatory. If you miss a lab session, it may not be made up unless you have a documented medical or family emergency. Quizzes may not be made up for any reason.

Required Textbook and Course Materials
Nofziger, M. (1995). OPTI 202L Geometrical and Instrumental Optics Lab Manual. Available at the EES Copy Center

Lab Notebook. All equipment for labs will be provided.
Examinations and Final Analysis
A weekly Lab Summary (4-5 pages) is due the week following your lab. The Final Analysis is a written report (2-3 pages) due at the end of the semester. It is a "critical analysis" of specific misunderstandings, misconceptions, or things you had trouble learning about.
