A polariser is an optical filter that passes light of a specific polarization and blocks waves of other polarizations. It can convert a beam of light of undefined or mixed polarization into a beam with well-defined polarization, polarized light.Where Analyser is an optical instrument which makes some angle with polariser
polariser filters are used to manage light at wavelength scale. As the filter is rotated, it either transmits or blocks the waves of light that are bouncing …
analyser analyse the light emmited by the polasiser and the combination is calles HPL
