Visible and Near-IR Microscope. This is an inverted microscope-based spectroscopy system with a 300 mm triple-grating spectrograph and dual (visible and short-wave near-IR) 2D array detectors. The visible CCD detector (1360 x 100 pixels) covers 300 to 1000 nm and a thermoelectrically cooled InGaAs detector (640 x 512 pixels) covers 800 to 1650 nm. The system is capable of performing absorption/reflection spectroscopy, photoluminescence spectroscopy (excitation provided by continuous wave and pulsed diode lasers), and visible photoluminescence lifetime measurements. A microscopy cryostat is available for measurements to 5K.
