Under the microscope #3 – Water fountain (with Spirogyra algae)
Here are some nice images of the alga Spirogyra. These algae have a spiral-shaped chloroplast. The video also shows other algae in colonies.
Under the microscope #2 – Sand from playground
Unless it is fine-grained, sand is a bit more difficult to observe under the microscope. Darkfiled microscopy shows quite nicely, that many sand grains are transparent (some made made of quartz).
Under the microscope #1 – Dandelion
Dandelion seeds are scattered by wind. Here I am having a look at the fruit of a dandelion. The fruits are the fine “hairs” that carry the seed. In the field of Biology the term “fruit” does not have the same meaning as in everyday usage.

Focus animation of a radiolarian
Here we have a focus animation of two radiolaria. The shells of these organisms are made of silica, which is similar to glass.
Observing Brownian motion
Brownian motion is the random movement of particles. This motion can be observed under the microscope, when looking at very small particles. In this case we will have a look at the fat droplets in milk.
The uSCOPE MXII digital microscope
The uSCOPE MXII microscope is a slide digitizer, which allows you to take overlapping pictures to be stitched together into a larger final image.
New Microscopy Forum!
The new microscopy forum is now online and everyone is invited to join.
White balance and image quality
Automatic white balance can greatly increase the information content of the images, it can also introduce color artifacts, however.
