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.

Theoretical calculations, based on geometrical and physicaloptics, are used to characterize Mirrors, Prisms and Lenses: a Text-Book: A Text-Book of Geometrical Optics: Southall, James Powe: Amazon.se: Books. Hands-On tool for students learning geometric optics. Students can learn how concave, convex and mirror lenses refract rays of light.

### 7 May 2018 The optical prescription of this camera lens (as described in Ref. 1) is given in the following table. The geometry consists of two doublet lenses

To understand images and image formation, all we need are the RAY MODEL OF LIGHT, the LAWS OF REFLECTION and REFRACTION, and some simple geometry and trigonometry. 3. GEOMETRIC OPTICS • The study of how light rays form images 4. REFLECTION AND REFRACTION AT A PLANE SURFACE 5. Understanding with Lenses in Geometric Optics G. TURAL* ABSTRACT: Students commonly find the field of physics difficult. Therefore, they generally have learning problems. One of the subjects with which they have difficulties is optics within a physics discipline.
