Question

What is S and P polarized light?

Answer 1

P - and S - polarization

1. P - and S - polarization are the two orthogonal linear polarisation states that are most significant for reflection and transmission.
2. P - polarized (German: parallel) light has an electric field polarized parallel to the plane of incidence, whereas S - polarized (German: senkrecht) light has an electric field polarized perpendicular to the plane of incidence.

1. Polarizers are used to select a specific polarisation of light. Reflective, dichroic, and birefringent polarizers are the three types of polarizers. Our Polarizer Selection Guide has more thorough information on which type of polarizer is best for your purpose.
2. The required polarisation is transmitted while reflective polarizers reflect the rest. Many thin wires are aligned parallel to each other in wire grid polarizers, which are a common example.
3. Light polarized parallel to these lines is transmitted, whereas light polarised perpendicular to these wires is reflected.
4. Brewster's angle is used by other reflecting polarizers.
5. Brewster's angle is a precise incidence angle that only reflects s-polarized light.
6. The transmitted beam becomes largely p-polarized while the reflected beam is s-polarized.
