Linear spectrometer

For a basic optical sample characterization we use a micro-​spectrophotometer (Jasco MSV-​370). Linear spectroscopy can be performed over a large spectral range starting in the ultraviolet regime at a wavelength of 190 nm up to the near-​infrared with a wavelength of 2500 nm. The micro-​spectrometer includes an optical mirror-​based microscope allowing for spatially resolved spectroscopic measurements in an area down to 20x20 µm² in transmission as well as in reflection geometry. Attaching a micro-​cryostat to the spectrometer allows us to perform linear spectroscopy even at low temperatures below 10 K.
