Hey - cool to see that there are others playing around with this idea! We’re also doing pollen microscopy at Biotop in Heidelberg http://biotop-heidelberg.de
Last week we took these pollen (this time extracted from Honey) images with a 10x plan objective in the open flexure microscope and PiCam.
But professionally, my understanding is that a 40x-60x objective would be required, which we will try soon.
One issue we are facing is the travel of the microscope. We would need to scan the entire area of the 22mm square coverslip, but can only do about a quarter currently with the range of the stage. @r.w.bowman do you think the Delta Stage would have a wider range?
Also, does anyone have a suggestion of a reference database of pollen images to identify them?
