Abstract
A small high pressure optical cell is described, together with the modified liquid helium cryostat that has been used in recording the infrared absorption spectra from samples held at very low temperatures and quasi-hydrostatic pressures up to 35 kbar. The use of a simple modification which permits uniaxial pressure experiments with this same equipment is also illustrated.Keywords
