Photoluminescence
Helium (He) or Liquid Nitrogen (LN2) cryostat options
Photoluminescence (or PL) and Raman are spectroscopy techniques providing information on optical and electrical properties of semiconductors and many nano-materials.
HORIBA Scientific Photoluminescence and Raman systems are able to accomodate fairly large cryostats system for measurements at low temperature, using liduid nitrogen (LN2) or liquid Helium (He) cryostats.

HORIBA Scientific mapping systems such as the LabRAM HR are used to work with these temperature cells, which, coupled with a mapping stage, allow for imaging of small features within the cell.
Raman and Photoluminescence Mapping systems from HORIBA Scientific are used for research or production environments.
