Subject Title
Geometric Optics

Subject Description

This subject expands on the theory of physical optics and relates it to specific optical systems. Students resolve geometric optics problems related to thick and astigmatic lenses, microscopes and telescopes.

Credit Status
One credit toward the Opticianry Diploma Program

Learning Outcomes
Upon successful completion of this subject the student will be able to:

Upon successful completion of this subject the student will be able to:
