Lenses are one of the most common components of optical instruments.

Astigmatism as a Defect of an Optical Lens. Astigmatism as explained in the previous section results for geometrical reasons even for perfectly spherical mirrors 

See how light rays are refracted by a lens. Watch how the image changes when you adjust the focal length of the lens, move the object, move the lens, or move the screen. geometrical optics is usually simpler.

Thin Lenses When the size of the physical and optical objects of a system are much larger than the wavelength of the light (or as λ → 0 ), we are in the realm of geometrical optics. Optical systems in which the wave nature of light must be taken into account (interference, diffraction) are called physical optics.

Experiment 21: Geometric Optics 121 Parallax is the e↵ect whereby the position or direction of an object appears to di↵er when viewed from di↵er-ent positions. This means that the object and the two observations points are not collinear. Fig. 21.4 and Fig. 21.5 represent the e↵ect. The apparent change in direction can be useful for de- Unit: Geometric optics. Physics library.
