Oxford Instruments’ optical cryostat, the OptistatTMDry is now available as an upgrade to Edinburgh Instruments’ FLS980 Fluorescence Spectrometer. This enables FLS980 users to do their experiments over a wide temperature range, from <3 to 300 Kelvin, without the need for cryogenic liquids. Measurements at these temperatures are essential for many different applications, for example in the study of semiconductors and non-linear crystals due to their weak photoluminescence at temperature above 70 K. The successful integration of the Cryofree® OptistatDry eliminates the need for a continuous supply of liquid helium for steady-state and time-resolved photoluminescence. New software was developed to allow the cryostat operation to be controlled directly from within the F980 operating software of the FLS980 Fluorescence Spectrometer, providing a fully integrated solution. This combination enables customers to run long experiments without interruptions that are often experienced when using liquid cryogens. E
