A good question Roldorf - but I personally have no idea!
An interesting activity though, I may have a rummage through a few blooms too if I get the time this weekend.
Any more pollen images to share would be very interesting my friend - I started my microscopy back in 2015 with pollen....
Hi, yes, thanks for the idea for MICAM - it's really very useful for measurement indeed. I've calibrated a set of 4x, 10x, 40x and 100x objectives for my BX40 - just need to add the new 60x now. It has the very useful ability to use a right-click context menu on an image to 'send to MICAM' - which opens the image in MICAM ready for use! Also, Canon's excellent EOS ethering utility program has the ability to specify a 'companion program' to launch with itself - MICAM could be specified there too.....
Here's a stomate from an epidermal-peel, measured with MICAM,
with perhaps gratuitous addition of an objective label and scale-bar

A really handy program - ToupView performs measurements, but with non-native images (i.e. non ToupCam USB camera) the text-sizes are always tiny, although the measurements are correct.
