Brewster window

Light is the interaction of electric and magnetic fields travelling through space. The electric and magnetic vibrations of a light wave occur perpendicularly to each other. The electric field moves in one direction and the magnetic field in another ‘perpendicular to each other. So, we have one plane occupied by an electric field, another plane of the magnetic field perpendicular to it, and the direction of travel is perpendicular to both. These electric and magnetic vibrations can occur in numerous planes. A light wave that is vibrating in more than one plane is known as unpolarized light. The light emitted by the sun, by a lamp or a tube light are all unpolarised light sources. As you can see in the image below, the direction of propagation is constant, but the planes on which the amplitude occurs are changing.

The other kind of wave is a polarized wave. Polarized waves are light waves in which the vibrations occur in a single plane. Plane polarized light consists of waves in which the direction of vibration is the same for all waves. In the image above, you can see that a plane polarized light vibrates on only one plane. The process of transforming unpolarized light into polarized light is known as polarization. The devices like the polarizers you see are used for the polarization of light.

KBr window

*Note: The flatness of thin and ultra-thin glass parts is limited for physical reasons. Please consider that the planarity of thin glass depends directly on the thickness since, with small thicknesses, the inherent mass already influences the flatness. Consequently, the flatness achieved with window optics based on thicker materials cannot be reached. However, the thin materials mentioned above are usually the best choice for the highest planarity at low thicknesses and typically cannot be outperformed by mechanical polishing processes.

Polarization, in Physics, is defined as a phenomenon caused due to the wave nature of electromagnetic radiation. Sunlight travels through the vacuum to reach the Earth, which is an example of an electromagnetic wave. These waves are called electromagnetic waves because they form when an electric field interacts with a magnetic field. In this article, you will learn about two types of waves, transverse waves and longitudinal waves. You will also learn about polarization and plane polarised light.
