A Witec Apyron Alpha 300R confocal microscope is housed in a glovebox to enable ambient-controlled Raman and photoluminescence measurement. The Witec microscope is fully automated with joystick controller to enabling automated change of lasers (532 nm and 633nm), gratings (300, 600, and 1800 grooves/mm), objective lenses (x5, x10, x50, x100), focus (z height) and stage motion (x-y location), etc. The detector can resolve peaks down to 10 cm^-1 (with 532 nm excitation) and has a 0.1 cm^-1 spectra resolution (with 632 nm excitation). A Linkam LTSE420P cryostage is available for variable temperature measurements from -196°C to 200°C and has 4 gold-plated tungsten tips for ­in-situ ­electrical measurements.
