This microspectrometer is enclosed in a glove box. This allows the user to measure Raman and photoluminescence spectra in the nitrogen atmosphere. Thanks to the combination with AFM the surface of samples can be mapped. For this purpose, three lasers with wavelengths of 442 nm (Kimmon Dual Wavelength HeCd, model IK5651R-G), 532 nm (Renishaw RL532 diode-pumped solid state), and 633 nm (Renishaw RL633 HeNe) can be used.

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.
