Key Differences
A polarizer is a device used in optics to transform unpolarized light into polarized light, usually by selectively filtering a certain orientation of waves. An analyzer, on the other hand, is a device used to examine or measure certain properties of polarized light, such as its direction, intensity, or degree of polarization.
Polarizers are often used in photography to reduce glare and improve color saturation. They work by allowing only light waves vibrating in a particular direction to pass through. Analyzers are employed in various scientific and industrial applications to assess the properties of polarized light, helping to reveal information about the material through which the light has passed.
In the context of polarized light microscopy, a polarizer is placed below the specimen to polarize the light before it passes through the sample. An analyzer is then placed above the specimen to analyze the polarized light that has interacted with the sample, providing insights into the sample's optical properties.
Polarizers are critical in devices like LCD screens, where they ensure that the light is polarized before it reaches the liquid crystals. Analyzers are used in spectropolarimetry to study the polarization of light from astronomical sources, providing valuable data about celestial bodies.
While both polarizers and analyzers deal with polarized light, their functions are distinct: polarizers modify the state of the light, while analyzers assess or measure the properties of polarized light.
