Polarizing filters are optical devices that transmit light only with a certain polarization. They are used in various fields including electronics manufacturing, scientific research and industry. In this article we will look at the operating principle of polarizing filters, their application and features of use.
The principle of operation of a polarizer is that light passing through it is divided into two polarized components - horizontal and vertical. Depending on the angle at which the polarization of each of them passes through the filters, the direction of the light changes. If the polarizers are perpendicular to each other, the light will be absorbed. If they are parallel, it will pass through them without change.
Polarized glasses are one of the most commonly used devices. These are special glasses that are a combination of sunglasses and polarizing filters. The main task of such a filter is to protect the eyes from the blinding effect of glare reflected from the surface of an object. But there is another side to using this filter. A polarizing filter, when light reflected from the road hits it, forms a picture with clear outlines, but only black and white. Unfortunately, such a filter is also not capable of conveying the entire gamut of colors perceived by the human eye. To increase sharpness, optical systems with additional elements, such as microlenses, are used. It is important to note that polarizing filters can be used both to improve image quality and to degrade it. For example, they can cause a loss of detail or create a redshift effect in photographs. Therefore, it is important to understand when and where to use polarizing filters.
**Polarized filter** is an optical device that allows you to filter the light flux, passing through only transverse waves. This reduces the amount of reflected light and increases the brightness and contrast of the image. Polaroid filters are used in photography, video, and digital imaging to enhance image clarity and brightness and reduce reflections from surfaces. They are popular as decorative
