Looking at salt under the microscope is a great learning activity for young students who are exploring how different materials look like when viewed through a microscope, especially when studying crystals, minerals, and other geometric shaped solid substances. This is because salt looks different when viewed with the naked eye, with a hand lens or …
Sand is one of the many fascinating materials to view under a microscope, given its distinct shapes, sizes, colors, textures, and the fact that how the sand looks is highly dependent on where it comes from. This is because the composition of sand depends on the local environmental conditions, and more importantly, the available rock …
The definition of depth of field and depth of focus in microscopy and how to calculate each one An important concept in microscopy is the depth of field, and the depth of focus, which are two related principles that are often interchangeably used. Both of these things have to do with the range of distance …
Light microscopes are made up of several important mechanical and optical components that all work together to make it function as efficiently as possible. One of these components is the iris diaphragm. Here is a guide on what the microscope’s iris diaphragm is, what it can do, and how it works, as well as other …
We all know about the basic facets of light microscopy, especially that of bright field microscopy, since it’s what we always encounter. But, there are lots of other types of microscopy techniques that are just as simple, but work so much better. One of these is a technique called dark field microscopy. It’s largely based …
Whether you are in an academic institution, research and development field, or commercial industry, more often than not, you can greatly benefit from having an in-house electron microscope. But before you make the decision of buying one, it’s important to first have an idea of how much an electron microscope costs, as well as all …
The beginnings of microscopy dates back to a few hundred years, when the first microscope was invented. This was the simple microscope, a rudimentary imaging device with just enough magnification to enlarge small objects. Despite its simplicity, simple microscopes are versatile imaging tools that are still used today in a variety of fields and disciplines. …
Our common perception of yeast is that it’s used to make bread, sometimes beer or wine. While that’s all great and all, these are actually not the only kinds of yeast. There are many more different types of yeast that can do a lot of different things. Today, we’ll answer all your questions about yeast, …
A microscope is a wonderful and invaluable tool that enables us to see things far beyond what the naked eye can see. Now, everything can be magnified to an indefinite amount of time. In fact, we have even invented microscopes that can let us see at the subatomic level. There’s just one problem. Enlarging an …
For many types of microscopes, especially light or bright field microscopes, some form of specimen sample preparation must be done before the specimen can be viewed under the microscope. Take for example a compound light microscope. It makes use of microscope slides to mount the specimen on, before loading it onto the microscope for viewing. …
