I am working on a research project related to ski tracks where I want to observe changes in the top layer snow grains. I have used a AmScope SM745T microscope with a 5MP MU500 previously and found that illuminating the track from beneath made a huge difference in the contrast and ability to see grains.
Is there any recommended hardware to improve the visibility of the top surface grains, lighting, new microscope, filters etc?
Im looking for signs of melting, re-freezing, new grains rolling in etc.
Edit: About magnification, a good viewport has been 1mmx1mm so far.
An important aspect is that it is easy to move from the track to allow skiers to pass, and then back to the exact same spot so some kind of sliding trolley etc would be helpful.
Thanks in advance!
