Being able to diagram an optics problem is an essential component of undertstanding how to arrive at a solution. Ray tracing through positive and negative lenses and lens systems will be reviewed. Please bring a pencil and paper with you. There is a problem set that reviews concepts from the first lecture. Please complete this but it will probably not be discussed unless there are questions.
The ways that light rays pass through media other than air will be discussed. Principles of refraction and relevant formulas will be reviewed. You should be able to calculate amount of light reflected from a surface, amount transmitted, and do problems that deal with how light is reflected through media , calculate incident and emergent angles and locate the apparant positions of objects that are in substances other than air. Please review the powerpoint presentation and complete the accompanying problem set prior to class.
The way light interacts wtih curved surfaces and reflective surfaces will be discussed. . Please review the powerpoint presentations and problem sets before lecture.
Refraction through thin lenses and discussion of toric surfaces as well as optics of prisms will be discussed. Please reviewe the attached lecture slides and complete the problem sets.
This lecture will cover a broad scope of topics ranging from effective power at a surface, vertex distance, how to transpose an Rx, how to hand neutralize an Rx. In addition, please review the lecture about lens materials, we will not likely have time to cover it in class.
Problems dealing with size of images on the retina, how things are magnified and minified when looking through glasses as well as a basic introduction to contact lens optics will be reviewed. Please reviewe the lectures and problem sets.
