Through this exercise, you will
- learn the basics of mounting, aligning and adjusting optical components;
- verify the lens maker and the magnification formulae:
- $ {1 \over S_o} + {1 \over S_i} = {1 \over f} $
- $ M = {h_i \over h_o} = {S_i \over S_o} $
- become familiar with image acquisition and distance measurement using the Matlab software.

Plot and discuss your results
- Repeat these measurements of $ S_o $, $ S_i $, $ h_o $, and $ h_i $ for several values of $ S_o $.
- Plot $ {1 \over S_i} $ as a function of $ = {1 \over f} - {1 \over S_o} $.
- Plot $ h_i $ as a function of $ h_o $.
- What sources of error affect your measurements?
- What is the uncertainty of your magnification measurement?
