Tell us more about "polarizer"

Unpolarised

Definition: A polarized light is a type of light that has both an electric and magnetic field. When light enters a polarizer, it is split into two beams that are in opposite directions to each other. This phenomenon is known as polarization.

Polarizer

Definition: A polarizer is a type of optical device that allows light to pass through one medium (typically glass or water) while blocking or scattering light from another medium (usually air). It works by creating an electric field in one of the media, causing it to vibrate and move. This vibration causes the light to scatter, which can be used for various applications such as optical communication, lighting, and security systems.

Polarising

Definition: Polarisation is a phenomenon in physics where light or other electromagnetic waves can be split into two or more beams depending on their direction. This effect is known as polarization and it occurs when light encounters an object with a certain orientation, such as a mirror, and then reflects off the surface of the object. In simpler terms, when light enters a polarizer or a lens, it splits into two or more beams depending on how much of the beam is oriented in one direction. This phenomenon can be

Polariser

Definition: A polarizer is a device used in optical communication systems to remove light from one direction and focus it on another. It works by blocking certain wavelengths of light, such as visible light, infrared, ultraviolet, or X-rays, which are absorbed by the material that forms the polarizer. Polarizers can be classified into two categories: single-pole and double-pole. A single-pole polarizer is used for transmitting only one direction of light while a double-pole polarizer is

Polarimetric

Definition: Polarimetric refers to a method of measuring light using the principles of polarization. This means that when light passes through a polarizing filter, it is split into its three primary colors (red, green, and blue) due to the different ways in which light interacts with the surface of the polarizer.

Photopolarigraph

Definition: Photopolarigraph is a type of polarimetric optical instrument that measures polarization in light. It consists of two mirrors, one for polarizing and the other for reflecting light. The polarizer allows different colors to pass through at different angles, while the reflector blocks certain colors or light rays. The term "photopolarograph" has been used historically but is now often used in a more general sense to refer to any instrument that measures polarization.

Depolarizers

Definition: A depolarizing agent is a substance that causes the neuronal membrane to become more conductive, thereby inhibiting excitability and increasing the potential of neurons. Examples include caffeine (which decreases neuronal excitability), propofol (which reduces neuronal excitability), and acetylcholine (which increases neuronal excitability).

Depolarizer

Definition: A depolarizer is a substance or device that causes an object to become more sensitive to electrical signals or stimuli. It can be used in various applications, such as in medical devices, electronics, and communication systems. The term "depolarizer" is often associated with the use of electric fields to manipulate electronic circuits.

Polarizing filter (polarizer)

Definition: Polarizing Filter (Polarizer) - A filter that separates colors based on their wavelength, enhancing color diversity or reducing interference with other colors. Detailed Definition: Polarization refers to the ability of light waves to be polarized in certain directions due to differing refractive indices (density or velocity). When a wave is polarized at one direction and not the other, it is said to be "polarized." In this context, a filter can effectively separate colors based on their wavelength, enhancing color diversity while reducing interference.
