If you’ve ever wondered what kind of microscope is used to see a virus, you’re not alone. It’s a common question, and the answer reveals the incredible power of modern scientific instruments. Viruses are far to small to be seen with a regular light microscope, so scientists need much more advanced tools. What Kind Of … Read more

If you’re getting new glasses, you’ll need your pupillary distance measured. This number ensures your lenses are centered correctly. So, how is a monocular PD usually recorded? It’s the process of measuring the distance from the center of your nose to the center of each eye individually. This gives your optician two precise numbers, one … Read more

If you’re new to microscopy, you might wonder which microscope uses visible light. The answer is the light microscope, also known as the optical microscope. It’s the most common and recognizable type, using lenses and light you can see to magnify small objects. This tool is a fundamental instrument in labs, classrooms, and even hobbyist … Read more

If you use a microscope, you’ve probably noticed that only a thin slice of your sample looks sharp at any one time. This is directly related to a key optical concept. What is depth of field in microscope? It’s the thickness of the specimen that remains in acceptably sharp focus at a single setting. Think … Read more

If you’ve ever looked through a microscope in a biology class, you was probably using a light microscope. But scientists have another, much more powerful tool. So, how are electron microscopes different from light microscopes? The core difference lies in what they use to see the world. One uses beams of light, while the other … Read more

If you’ve ever wondered who made the electron microscope, you’re about to find out. This incredible invention didn’t come from a single person, but through the brilliant work of several scientists across decades. It changed science forever by letting us see the invisible world of atoms and viruses. Before this tool, light microscopes were limited. … Read more

If you’ve ever wondered who invented a microscope, you’re not alone. This simple question opens a door to a fascinating story of curiosity and incremental discovery. The microscope is one of humanity’s most important tools, letting us see a world that was once completely invisible. Its invention wasn’t a single “eureka” moment by one person, … Read more

If you need to view a specimen under a microscope, you first need to know how do you prepare a microscope slide. Proper slide preparation is the most important step in microscopy, as it turns a sample into something you can clearly study. This guide will walk you through the main methods, from simple dry … Read more

You might wonder, can you see an atom in a microscope? The short answer is no, not with a regular light microscope. But with incredibly advanced technology, we can now visualize atoms directly, which is a stunning achievement of modern science. This question gets to the heart of how we understand the building blocks of … Read more

If you’ve ever looked through a microscope and wondered why some details are sharp and others blurry, you’re thinking about resolution. At it’s core, what is resolving power in a microscope? It’s the absolute fundamental ability of the microscope to distinguish two separate points as distinct entities. Think of it like this: if two stars … Read more
