Optical Microscopes
Within the Metallography Lab, optical microscopes including three MEF3 Reichert metallographs, two Nikon Optiphot binocular microscopes and Olympus and Wild stereo macroscopes, are utilized to provide users up to 2000X images. Methods include bright field, dark field, oblique illumination, polarized illumination, differential interference contrast, specimen fluorescence and limited transmitted light microscopy. Images obtained can be documented with 4X5 inch positive prints either color or black and white or as digital micrographs from a Reichert light microsope coupled with PAXIT digital image capture systems.
