3 days ago I satisfied one of my childhood desires to peek under the hood of the visible world so I bought a biological microscope. I did not want to boy a cheap digital one because it didn't have the optical capabilities that I wanted (1000x oil immersion, at least semi plan objective lenses), the possibility to add a dark field condenser (which I will) so I had to figure out a way to capture the images. One solution would have been to buy a microscope camera or modify a HD webcam. But in the end I figured that my phone captures the images in full HD and also I could use it as a digital screen for the microscope also without investing anything else. So there you have it. The maximum optical magnification of blood captured using a phone.I think there are no HD microscope vids on youtube so I think these might be the best. The first part contains images of living blood (mine) on 100x, 400x and 1000x(oil immersion) using a standard 10x sight. The last part contains some images of dried up blood after one day. Mostly you will just see red blood cells (without oxygen taken from the vain and not an artery) and some other type of cells that I don't know exactly what they are yet.
