In Olin 318 we have research microscopes set up for transmitted and reflected light petrographic and photographic work. Both microscopes can be used with the two available cameras. A dedicated laptop computer runs the image acquisition software.
Here are the field diameters you can see through the occular, and for the camera on the trinocular head.
