Lecture 11 Aberrations • Monochromatic Spherical Aberration – Coma – Astigmatism – Field curvature – Distortion Chromatic Spherical Aberration • Remember: The non paraxial beams intersect earlier How can we get rid of it ? Coma: principle planes are not planes Field curvature: focus plane is curved Astigmatism

Chromatic Aberration Caused by dispersion Focal length depends on wavelength axial = n i " 1 ( ) # $ Lateral C.A. The size of the images is different Achromatic doublets Let’ s use a lens combination: We need to have For d=0 For Yellow: Material properties Characterization of the dispersion Material properties Dispersive Power V Abbe Number What happens when you use identical material ?

8.8. Mirrors Planar Mirror In a planar mirror and normal incidence just the direction of the light propagation is changed. This has one important consequence: We change from a right handed coordinate system to a left-handed one (inversion) Inversion by a mirror Left becomes right Why not up /down ?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
