Synopsis:

The course gives a thorough interpretation of the principle of image forming by planar and spherical surfaces under the laws of geometric optics. Monochromatic and colour aberrations are also explained.

Requirements:

Syllabus of lectures:

1. Light as electromagnetic radiation. Wavefronts and rays. Index of refraction. Optical path. Polarization.

2. Fermat's principle. Refraction and reflection at a plane surface. Total internal reflection. Planparalel plate. Handeness and parity.

3. Plane mirro and systems of mirrors. Refraction prisms: types, applications.

4.Crown and flint glass, dispersion, Abbe number. Dispersion prisms, minimum deviation position.

5. Curved optical surfaces. Transfer equations, ray tracing. Cardinal points and planes.

6. Focal length, optical power. Magnification: transverse, axial, angular.

7. Centred system of optical surfaces: cardinal points, focal length, magnification, transfer equations.

8. Thick lens: image forming, ray tracing, types.

9. Thin lens: image forming, ray tracing (graphically and algebraically).

10. Systems of thin lenses, system focus. Afocal system.

11. Aberrations of optical systems: monochromatic, chromatic. Corrections of aberrations. Doublets.

12. Optical fibres.

13. Colorimetry. Colour mixing, colour systems.
