What is the polarizer?

The

polarizer changes electromagnetic energy, such as visible light, from a mixed or unbreakable beam to a single polarized beam. Many optical tools such as cameras, binoculars and microscopes use this technology as integrated or screwdriver devices to view specific light types. There are two general types of polarizers: absorbent and breaking beams.

The absorption polarizer filters unwanted rays by absorbing and leaves only the desired ones. The most common type of absorbent filter is a wire grid, which allows you to pass only one type of beam. Polaroid ™ is one of the most popular brands of the name of the absorbent polarizer, because it uses stretched polyvinyl alcohol polymer chains to filter light. Famous, but now obsolete, the immediate picture of the film has used this technology and is still used as a film for sunglasses, liquid crystal displays and microscopes. As well asThe magnet has a positive and negative end, as well as a beam of light, although the difference is not so easy to understand. Polarization of light through the distribution of the beam generally produces one clean beam and one mixed beam, rather than two pure rays.

The most common use of the polarizer is in the photo. Fastening the lens reduces reflections and increases color saturation. The contrast between the clouds and the sky is more pronounced and the details like the leaves tend to look sharper when using the polarizer. The polarizer is most effective when shooting at an angle of 90% from the Sun. It is not effective for the photographer to shoot with the sun on his back.

Astronomers use polarizing filters with their telescope eyepiece to focus on the celestial object. The filter reduces the glare without changing the actual color of the object. This glare reduction allows a clearer view of the object and the ability to see more details and anomalies of the terrain.

microscopes taKé use polarizers to study different materials. The polarization microscope uses two types of filters, the polarizer located under the sample and the analyzer located above. With the pattern between these two, a light environment is allowed. The analyzer can be moved to or from the field of view to provide the observer of different levels of polarization. This technology allows viewing the reflected or transmitted light. Reflected polarized light is particularly useful for studying oxides of minerals and sulphides, silicon wafers and metals.
