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:

1. Analyze the behavior of light through thin astigmatic lenses in air and calculate the location and size of the circle of least confusion


2. Perform calculations to determine sphero-cylindrical lenses powers in various meridians and when combined.


3. Analyze the behavior of light through a thick lens and lens systems in air and

apply formulas to determine the back and front vertex powers .


4. Explain Gullstrand's simplified schematic eye, state its parameters and calculate the total power of the human eye.


5. Define lens stops and calculate the lens stops of various eyepieces and


6. Describe telescopic and microscopic lens systems and calculate their

magnifying power

7. Explain the concept and identify applications for angular magnification

Modes of Evaluation
In Seneca College Health Science Programs, a minimum grade of "C" (60%) is required for Promotion.  

Module Tests  30%
Mid Term Exam 30%
Final Exam 40%
Total  100%

Students must pass the final exam to pass this subject.

Testing dates have been pre arranged and are non-negotiable. If a test is missed, students are required to provide documentation such as a doctor's certificate stating the
illness, along with a written request for a make-up testing privileges within 7 days following the date of the test. Make-up examinations will be granted for extenuating
circumstances only at the discretion of the instructor. 

Cheating and Plagiarism:
Using another's ideas as one's own, as well as copying directly from books, magazines, reports, and other sources without acknowledgment is plagiarism.
Cheating and plagiarism constitute unacceptable behaviours.  Such offenses occur when a student violates the procedures governing the administration of examinations, tests or
other means of evaluating student achievement in a subject or program.

A promotion meeting will be convened to review alleged instances of cheating or plagiarism.

The minimum penalty for a first offense during a student's attendance at the College will be loss of credit of the evaluation involved or a more stringent penalty consistent with the c

A second offense may result in the immediate expulsion of the student from the College for the remainder of the current semester and two subsequent academic semesters.

Where there is sufficient evidence to assess a penalty, all relevant information will be maintained in the student's file.  The student has the right to appeal the decision of the College,
consistent with academic policy.
