Micro-Spectroscopy Workstation

The Micro-Spectroscopy Workstation is capable of providing both spectroscopic measurements and microscopic imaging of samples from functional nanomaterials to thin films to proteins. Built upon a Zeiss Axio Observer D1 inverted microscope, the workstation is equipped with two incident-light halogen lamp illuminators, a 100-Watt Hg lamp, and a Zeiss AxioCam MRC color CCD camera. In addition, three optical spectrometers, coupled to the microscope via multi-mode fiber optics, are available for micro-spectroscopic characterization (transmission, absorption, reflection, and fluorescence) with emission spectra ranging from UV-Vis (300-900 nm) to NIR (900-1700 nm). A dark-field condenser attached to the microscope is especially useful for studying the optical properties of nanomaterials through surface plasmon spectroscopy. The workstation is also equipped with an InGaAs focal plan array (FPA) NIR camera to image thermal and optical emission in the Near-Infrared (NIR) region. Micro-Raman spectroscopy with laser excitation of 531 and 647 nm.
