HEXA-BEAM Laser

 HEXA-BEAM Laser

The Hexa-Beam Laser developed by Photonics Technologies allows teachers and students to conduct various scientific experiments in their physics undergraduate labs using different wavelengths without the need for re-alignment of the laser set up and with one single light source.

There are six wavelength modules in the laser which can be conveniently switched by one operational knob.  The different wavelengths are emitted along the same optical path and are vertically polarised.

The ease of set up and its use makes the Hexa-Beam Laser a great tool for a number of physics experiments.  We have conducted some experiments and have developed lab scripts that will be provided for use to the lab technicians and their students in the labs together with the Hexa-Beam Laser:

Biot’s Optical Rotation Experiment (also known as Biot’s sugar experiment)

In this simple experiment, one can learn about the physics of light scattering, polarization, chiral chemistry and fluorescence.  This experiment has been demonstrated by Durham University in detail – link to detailed experiment description.

Rotation of the Plane of Polarisation

Sugar solution was used to rotate the plane of polarisation of linearly polarised light dependent on the wavelength.

 The Faraday Effect

This experiment describes the rotation of the plane of polarisation of linearly polarised light due to the presence of a magnetic field.  As well as our lab script, this experiment has been conducted with Durham University and their description can be seen here.
