Infrared imaging of samples in ultrahigh pressure diamond anvil cells
Abstract
We describe an experimental platform that generates infrared images of micrometer-sized samples in the high pressure region of a diamond anvil cell. Using a 2.3 μm laser as a source of radiation, the system will be particularly useful in identifying hydride superconductors, which exhibit an anomalous temperature dependence of reflectivity in the 2.3 μm region. Our system shows an intensity stability within 1% when the sample temperature is swept from 100 to 300 K. The spatial stability is of the order of a few micrometers in the same temperature range.
