Principle

Linear polarised light passes through a polarisation filter. Transmitted light intensity is determined as a function of the angular position of the polarisation filter.

Benefits

The principle that Polaroid glasses work on
Introductory yet quantitative experiment to polarization
Straightforward simple setup

Tasks

The plane of polarisation of a linear polarised laser beam is to be determined.
The intensity of the light transmitted by the polarisation filter is to be determined as a function of the angular position of the filter.
Malus' law must be verified.
