Standard spectroscope operating under ambient atmosphere. The instrument has two chambers available:
1. Linkam temperature stage
2. Custom made chamber with an option of four-point conductivity measurements and filling with different gasses.
Description
Schematic view of the photoluminescence and Raman spectroscopy setup in the Institute of Physics of the ASCR, v.v.i.: 1a/1b-Renishaw REFLEX micro-spectroscope with inVia confocal Raman microscope 2a/2b, 3-glovebox, 4,5-large and small chamber, 6-Ntegra NT-MDT AFM, 7-motorised mirrors, 8-lasers. The detail shows the beam and signal path through the 1b and 2b. 9 is the plasma filter, 10 bandpass filter, 11 objective, 12 sample, 13 spectrometer and 14 the CCD detector.
