Electron Microscope Mystery 7
Posted: May 6, 2013 Filed under: Microscopy | Tags: microscope, mystery, SEM 9 CommentsIt’s time for another microscope mystery!
The field of view here is about a millimeter. What is it?
Update, 4:50p: This is proving to be a tricky one! Here’s a zoomed-out view.
Update, 5:02p: Hooray! @poikiloblastic guessed right, it’s a key.
Fuzzy Science 
The corner of an Iphone/Ipad?
Good guess, but nope – it’s smaller than an iPhone.
That’s quite a stumper… appears the corner of something. But what?
Corner of a business card?
Smaller than that, and not made of paper.
Corner of a razor blade?
Closest guess yet! It is metal, and just a bit larger than a razor blade.
I had no inkling initially, but after the zoom out I would go with key.
Nice job!!
