5.2) Polarisation (anisotropy) studies
For polarisation experiments, a Cairn filter cube with an integrated polarising beamsplitter cube*
is also available as an additional accessory. In addition, a rotating 25mm polariser is available to
act as a ‘clean-up’ for the reflected S wave.
* Please note the polarising beamsplitter cube is very fragile!
1. Insert the
polarising beamsplitter cube
by removing the
cube door
and allowing the magnetic
cube to locate within the OptoSplit.
2. Replace the
door cover
.
3. Remove the blank cover for the
auxiliary drop-in position: reflected path
. (Note the blank hold-
ers will have no angled thread indictor and act as a protector for this pocket).
4. Insert the
rotating polariser drop-in
into the reflected auxiliary position.
5. The half-width blank auxiliary holder supplied will also be required to fill the space once the
rotating polariser is in place.
6. Rotate the polariser until the reflected image (on the right-hand side) achieves maximal intensity,
indicating the correct orientation.
