Micro Modular spectroscopy
Micro Modular Spectroscopy is a home-build setup equipped with a spectrometer (Shamrock 500i, Andor) and a thermoelectric cooled Si CCD (Newton BEX2-DD, Andor) and PylonIR InGaAs CCD. The spectral range of the system is 200 nm to 1750 nm. It is equipped with a 532 nm CW laser (Gem532, Novanta Photonics) as an excitation laser with 0.7 um beam diameter (with 100X, NIR, 0.7 NA objective) and a XYZ piezo sample stage (20 nm step resolution). With 1800 g/mm the spectral resolution is 0.6 cm-1, and Raman wave numbers range is about 90 - 10000 cm-1.
In this experimental setup many different spectroscopic techniques can be employed light to interact with matter and thus probe certain features of a sample to learn about its structures and optical properties.
