What happens when circularly polarized light goes through a polarimeter? In my experiment the polarimeter is made up of two crossed PEMs and a polarizer.

If you know how a linearly polarized light is affected by a polarimeter, extending it to circularly polarized light is not too difficult.lcr2139 said:What happens when circularly polarized light goes through a polarimeter?

What feature of the PEM is at these angle?crossed PEMs mean that one is at 0 degrees and the other is at 45 degrees.

Circularly polarized light refers to light waves that vibrate in a circular motion. Unlike linearly polarized light, which vibrates in a single plane, circularly polarized light rotates as it travels. It can be either right-handed (clockwise rotation) or left-handed (counterclockwise rotation).
Circularly polarized light can be produced through various methods such as passing linearly polarized light through a quarter-wave plate or using specialized filters. Another way is by using specialized lasers that emit circularly polarized light directly.
A polarimeter is a scientific instrument used to measure the amount and type of polarization in light. It consists of a polarizer, an analyzer, and a detector. It can determine the polarization state of light, including whether it is linear or circularly polarized.
A polarimeter measures circularly polarized light by passing it through a polarizer, which only allows light waves to pass through in a specific direction. The analyzer then detects the intensity of the light, and by comparing it to the intensity of linearly polarized light, it can determine the degree of circular polarization.
Circularly polarized light and polarimeters have various applications in scientific research and technology. They are used in fields such as astronomy, microscopy, telecommunications, and materials science. They can also be used to analyze the structure and properties of molecules and study the behavior of light in different environments.
