He-Ne Laser,  Unpolarized

Ideal light source for all experimental setups in which an intensive and parallel light bundle is required (e.g. diffraction, interference or holography). As a result of the linear polarization, this laser is also suitable for experiments on the rotation of the plane of polarization and on light modulation (e.g. saccharimeter and the Faraday, Kerr and Pockels effects). With key switch, swing out grey filter to attenuate the beam, stand rod and plug in power supply.
