Thanks to a very generous donor, we now have a brand new Compound Microscope! It’s the OMAX 40X-2500X Full Size Lab Digital Trinocular Compound LED Microscope with 14MP USB Camera and 3D Mechanical Stage.
Here are some detailed specs:

Software compatible with Windows XP/Vista/7/8/10, Mac OS and Linux operating system - Capturing microscope images, recording live video, measuring lengths, angles, areas, editing images - USB cable included
Once you hook up your laptop with the cables, you can download the software/drivers to get up and running. We were able to do this without too much difficulty. A company called Carolina sells live samples, so we looked at mixed infusoria, volvox globator, ameoba proteus, hydra and mixed protozoa with the scope.
Watch the amoeba change shape. Towards the end of the clip you’ll see some much smaller bacteria moving around.
