Lasers for Undergraduate Labs HEXA-BEAM Laser
The Hexa-Beam Laser is designed to switch between up to six different wavelengths without the need to realign the equipment. This is done by rotating one single knob.
This allows for the physics experiment to be conducted at different wavelengths, whilst ensuring that other critical variables remain controlled. The different wavelengths are emitted along the same optical path and are vertically polarised.
The HEXA-BEAM Laser contains as standard the 405nm, 520nm, and 650nm modules. Up to a total of six wavelengths can be included upon request.
PHYSICS EXPERIMENTS
The ease of set-up and use makes the HEXA-BEAM Laser a fantastic tool for a number of physics experiments. We have conducted physics experiments and developed lab scripts that will be provided for use to lab technicians and students in the undergraduate labs together with the Hexa-Beam Laser:
Experiment Descriptions:
1 Biot’s Optical Rotation Experiment, also known as Biot’s Sugar Experiment
In this simple experiment, one can learn about the physical of light scattering, polarisation, chiral chemistry and fluorescence. This experiment has been demonstrated by Durham University in detail.
2 Rotation of the Plane of Polarisation
The sugar solution was used to rotate the plane of polarisation of linearly polarised light dependent on the wavelength.
3 The Faraday Effect
This experiment describes the rotation of the plane of polarisation of linearly polarised light, due to a magnetic field. As well as our lab script, this experiment has been conducted with Durham University.
