1. Goal of the work: study the principles of constructing the path of rays through thin components and the principles of forming an optical system circuit using a computer-aided design system.

2. Tasks:

Part 1.

1) build the path of rays through thin components using the computer-aided design program AutoCAD (see Annex 1);

2) calculate image position, lens magnification, image size using thin lens formula;

3) compare the results of construction and calculation;

4) make your conclusion.

Part 2.

1) build a cemented doublet scheme in the computer-aided design program AutoCAD (see Annex 2);

2) put sizes;

3) take a screenshot from the program and insert it into the report;

4) set the optical system in the OPAL program (see file “Introduction to the OPAL program”);

5) take a screenshot of the ray path in the optical system and insert it into the report;

6) take a screenshot of the Paraxial characteristics and insert into the report;

7) formulate conclusions.

3. The content of the work

Part 1.
