Phase contrast microscopy is an effective and convenient method of boosting contrast, revealing hidden details in transparent and unstained specimens. It was invented by Dutch physicist Frits Zernike in the 1930s, who was awarded the Nobel prize for his discovery....
On the side of almost every microscope, no matter how cheap or expensive, you’ll find the focus adjustment knobs. Unassuming yet essential, these little black dials determine whether you see a crystal-clear image or a blur. Here’s a quick overview of the coarse and fine adjustment knobs, and how they work.
The mechanical stage is a vital yet unappreciated component of any microscope. Sitting below the objective lenses, it’s the stage (or platform) upon which your slides and samples sit. It both keeps your slides steady and allows you to move those slides with smooth precision. Here’s a quick overview of the humble mechanical stage.
The ever-shrinking size of electronic components makes a microscope essential for PCB inspections. But not all microscopes are created equal – and using a subpar setup for extended periods can leave you sore or even injured. If you spend a reasonable amount of time inspecting PCBs, you can make your job easier and safer by switching to a digital microscope like the Dino-Lite AM73915MZTL.
Instead of shining light directly through your sample, darkfield microscopy places a circular blocker known as a ‘stop’ in the way. The stop blocks any direct light from hitting the sample, allowing only the angled light that can sneak around the edges to get past. This angled light would ordinarily miss the objective lens, leaving the image completely dark (the ‘dark’ in darkfield).
Don’t take the humble glass slide for granted. These unassuming little rectangles lie at the heart of casual microscopy and professional scientific research alike. Despite their simple appearance, they come with a surprising variety of features and benefits. Let’s take a quick look at the types of plain glass microscopes slides you might encounter.
Introducing the new and improved Dino-Lite AF7115MZT, a remarkable handheld digital microscope with wi-fi connectivity.This upgraded model offers enhanced optics and a host of features for those seeking high-quality microscopy on-the-go. Let’s delve into its impressive capabilities.
Measuring cells and microorganisms under a microscope isn’t as simple as whipping out a tape measure. To measure truly microscopic things, you need to install a useful tool known as a reticle or eyepiece micrometre. And to properly calibrate it, you’ll need a special glass microscope slide known as a stage micrometre. Once calibrated, the reticle will allow you to make accurate measurements through your microscope quickly and easily.
If you’re interested in making the most of your microscope, you’ll want to get to grips with the condenser and aperture diaphragm on your scope. These essential components play a critical role in the quality of your images – and you’ll need to understand a little of their nuances to get a sharp, well-contrasted look at your samples.
