Microscopes have been an essential part of the scientific world to help researchers study the world around them. From hand-held microscopes to compound light microscopes and electron variants, microscopes have come a long way. The objective lenses hold significant importance among the different parts of a microscope; they are critical for observation and image formation that you see in the eyepiece. This article covers everything about objective … [Read more...]
How to Take Pictures Through a Microscope
Taking photographs through a microscope can be challenging as most microscopes lack built-in cameras. Then, how to take pictures through a microscope? You can take images through a microscope using a microscopy camera, mobile phone, or DSLR. The image quality will depend on your microscope's magnification, resolution, and camera quality. You can also record videos and view the multimedia on a screen. So many options allow you to choose which … [Read more...]
Why is it Difficult to Observe Individual Chromosomes with a Light Microscope During Interphase?
DNA and chromosomes are critical to cell division and multiplication. They ensure that each daughter cell receives an equal amount of genetic material. Division either occurs through mitosis or meiosis according to the cell’s need. While you can observe the process under a compound microscope, some aspects may not be very clear. One common question regarding mitosis observation is, “Why is it difficult to observe individual chromosomes with a … [Read more...]
What does the Adjustment Knob do on a Microscope?
Microscopes are fragile and complicated instruments with various parts functioning together to produce magnification. While they look rigid because of their metal body, microscopes have numerous important and delicate parts important for their functioning, such as the adjustment knobs. Adjustment knobs do not seem to directly contribute to magnification like the eyepiece, objective lens, or the stage. So, what does the adjustment knob do on a … [Read more...]
What is a Scanning Tunneling Microscope
Electron microscopes have been an incredible advancement in the microscopy world. They allowed us to view specimens magnified millions of times to study the intricate details at the cellular and atomic levels. There are typically two types of electron microscopes; scanning electron microscope (SEM) and transmission electron microscope (TEM). The scanning tunneling microscope, however, is another type of electron microscope that uses the quantum … [Read more...]
