Description
Summary:A scanning fluorescence spectrophotometer intended for measurement of the ruby R1 lines in a high‐pressure diamond anvil cell is described. A rigid framework supports the electronic and optical components and an X Y Z translation stage to hold the pressure cell. Innovations include a digital monochromator scan controller, the automatic placement of tick marks on the recorder output at 0.1 nm intervals, and light detection with a photodiode. The unit is compact, weighs 50 kg, and requires only a chart recorder for operation as an automated high‐pressure measurement station. These features allow easy shipment and reassembly at remote experimental sites.
