Active vs Passive laser stability

24 March 2021

It is a daily task to ensure the laser beam points exactly to where it should be in your physics lab.  Active vs Passive laser stability is a key question that occupies researchers all the time.

Smart electronics is the answer!  We can stabilise your laser with specialised equipment which will ensure a controlled laser beam through a continuous feedback loop.

Dr Thomas Kinder explains how in the video below:

The New Product For The Research Physicist

3 March 2021


If you are running various physics lab experiments for your students that require different wavelengths, wouldn’t it be great to do that without changing the set up from scratch?

The HEXA-BEAM Laser can do just that.

With one simple laser source, you can select your laser colour at the turn of a knob!

Experiment with the HEXA-BEAM Laser

2 March 2021

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)

Send the laser beam through a sugar solution and watch the experiment develop in front of your eyes.  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 Effecthexa-beam diagramatics - Alt text

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.

Mirror Mounts- A benchmark for stability and precision

16 September 2020

Our Optical Mirror Mounts come in a variety of types and characteristics to deliver exceptionally high stability for laser beam and delivery:

  • Manufactured to exceptionally fine tolerances, providing a new benchmark for stability and precision with a fine- thread screws with a pitch of 170 TPI
  • Constructed from specially treated materials to prevent movements from mechanical stress and changing temperatures.

You can design your own configuration – chose from different front and back plates, adjusted screws, and colours!
