Abstract
We have designed and constructed a compact high pressure light scattering cell which can hold a cube sample as large as 10×10×10 mm3. The cell dimension is about 10×8×10 cm3, and the body material is beryllium-copper alloy. The large sample ensures a low stray light level and the new design for the light collection window permits a large light collection angle (18°). The simple sealing method enables even inexperienced personnel to use this optical cell. We have tested the cell up to a pressure of 0.8 GPa by recording the low-lying Raman spectra of a ferroelectric crystal KH2PO4.
