My normal flow of work with micrometeorites is to spend 10-20 days searching sediments, picking and cleaning, ID and storing MMs. After that, I then shift to imaging mode, where I am taking pictures and editing for 10+ days. I do this to be more efficient with my activities and with the space that I have.
I use a stereo zoom microscope for searching sediments, and I use an Olympus metallurgical microscope (BHM) for closer looks and imaging.
My preferred imaging set-up does not have a binocular head to see what is in the scope, and to reduce the number of times that I have to remove photo-eyepieces (2.5x NFK, 3.3x NFK...), I am trying to do better at predicting which optical combination is best for each micrometeorite that I am imaging. To that end, I have created a table that gives me how big each optical combination will allow for imaging. This should help me choose the optics for each MM more efficiently.
While the field of view measurements could probably be calculated from data on each objective and photo-eyepiece [see Alan Wood's site in his Olympus Microscope section for lots of great info on Olympus microscopes, photography, and optics-https://www.alanwood.net/], I choose to avoid the math and just calculate it using the view through the camera sensor. Approximate values... the numbers will probably change. I haven't pulled out my MSPlan objectives in a while- so I don't have those numbers yet.
I hope this is helpful for some. Comments and questions are always welcome.
