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 diameters of the round fields you see by eye, and the widths of the images the Paxcam camera acquires:

 

BH2 reflected light | BX41 transmitted light
Objective Field diameter Camera image width | Objective Field diameter Camera image width
2.5x 6.2 mm 4.6 mm | 2x 11 mm 8 mm
5x 3.1 mm 2.3 mm | 4x 5.5 mm 4 mm
10x 1.6 mm 1.2 mm | 10x 2.2 mm 1.6 mm
20x 0.78 mm 0.58 mm | 20x 1.1 mm 0.80 mm
50x 0.31 mm 0.23 mm | 40x 0.55 mm 0.40 mm
100x 0.16 mm 0.12 mm | 100x 0.22 mm 0.16 mm

 

Note: Keep the microscopes covered when not in use. Thank you.
