Electron microscope is a high power microscope that uses a beam of accelerated electrons instead of visible light for illumination and image formation. Due to very short wavelength of electrons, it can overcome the diffraction limit of light microscope lenses. Hence, it gives very high resolving power and very high magnification as compared to compound … Read more
What is Polarizing Microscope? Principles of Polarized Light Microscopes The Light Path and Image Formation of Polarized Light Microscopes Parts of a Polarized Light Microscope 1. Light Source – usually a halogen bulb that gives bright white light; it must be stable so the color don’t change by heating or voltage drift. 2. Condenser – … Read more
Multiphoton microscopy is a cutting-edge imaging technique widely used in biology and medicine to study living tissues with minimal harm. Instead of relying on single high-energy photons like conventional microscopes, this method harnesses multiple low-energy photons that act together to produce a fluorescent signal. The trick lies in timing—when these photons strike a molecule simultaneously, … Read more
What is Fine Adjustment Knob? Particularly in high magnification levels, the fine adjustment knob is an essential part of a microscope as it helps to achieve exact and crisp focus. Particularly in the study of cells, microscopes are essential instruments in scientific inquiry as they let us view objects beyond our human sight. Under a … Read more
It is designed in a way that is compact and portable which is why it’s called a pocket’. They’re pocket-sized however some are bigger. Their size is not enough to be able to hold a mirror in order to put the image in the proper place. However, they contain a small stage where one can place an object to observe. They’re portable so that they can be utilized by both professionals and amateurs according to the task they’re designed to fulfill.
What is transmission electron microscope? A transmission electron microscope (TEM) is an electron microscope that transmits electrons through a sample to observe it. Scientists use transmission electron microscopes to analyze materials and examine their microstructural and compositional properties. A transmission electron microscope transmits a highly focused beam of electrons through a sample to observe and … Read more
This reflects the seemingly marvelous developments that have occurred from the history of microbiology to the present day. Advances in technology and subsequent research in the field over the years have meant that once we learned how to study these tiny creatures, we only grew in appreciation for these vital little agents. But in 1590, … Read more
What is Inverted Fluorescent Microscope? Ever peeked into the world of living cells? Scientists use a nifty tool called an inverted fluorescent microscope for this. Unlike regular microscopes, this one flips the script—literally. Imagine the lenses sitting above the sample and the light source shining from below. This upside-down setup makes it perfect for studying cells chilling at the bottom … Read more
What is an Inverted Microscope? An inverted microscope is literally an inverted microscope. The lights and lenses are positioned above the specimen stage and the objective lenses are below. This allows the user to critically observe the samples from below; this is important because many living specimens and cells to be observed are in petri … Read more
Objects are magnified under compound microscopes are mounted onto microscope slides. Made from plastic or glass Slides measure approximately 1×3 inches in size and range from 1mm-1.2 millimeters thick.
