Pictured above are the two microscopes used in our laboratory. On the right is the Raman microscope. This instrument excites the sample with a 532nm laser pulse and can measure the Raman shift of these photons out to 5000 cm-1 The Raman microscope is capable of measuring samples one atomic layer thick with cross sectional areas of 1µm2. The general use optical microscope shown on the left includes a 5 megapixel digital camera for device characterization. In addition this microscope includes a full set of polarization optics for Kerr microscopy. The general use microscope can be run in reflection or transmission modes.
