Figure 1
A schematic of the laser mounting and alignment device viewed in profile (top) and from above (bottom), with the path of the laser shown as a broken line. The laser beam travels vertically down and is reflected by a mirror, so that it travels alongside the detector arm until two prisms redirect it to the front of the detector, where a second mirror directs the beam up towards the sample. Minor adjustments to the alignment of the beam can be carried out using small screws to modify the angle of the mirrors. A photograph of a crystal on irradiation is shown inset.
