The human eye is a complex organ that enables us to perceive, understand and explore the world and beyond. It's rightly been called a "miracle of design" in our body. Yet this brilliant organ has limitations in seeing small molecules
In 1590 the two Dutch spectacle makers discovered that when several magnifying lenses were put inside a tube, the objects seen through the tube were larger. This idea resulted in the first microscope but the images produced by these microscopes were unclear, they were more of a novelty and not used for any form of scientific research.
This is a very basic question that depends on a lot of factors but to start with the most important factor is your application. What you need to see and what you want to do with that image will determine what kind of microscope you need; contrary to common knowledge, there are many different types of microscopes, and no single microscope can view everything. Much like any industry, the key to success with microscopy is having the right tool for the job at hand.
There are many different types of objectives available for microscopes, but without a basic understanding of how they work, it can be difficult to know which ones are best suited to the specific needs you have. That's why this article takes you through the basics points to keep in mind ,so that you'll have a better idea of what type is right for your needs.
Optical microscopes are broadly categorized into two types, upright and inverted, based on the positions of the light source and the objective. The basic difference between an inverted and an upright microscope are as follows:-
Microscopes have opened up many doors in science. By using Microscopes scientists, researchers and students were able to discover the existence of microorganisms, study the structure of cells and see the smallest parts of plants, animals and fungi.
We know that the major uses of the microscope are to view objects which are so tiny that they are invisible to the naked eye. There are various applications of these devices depending...
A simple microscope works on the principle that when a tiny object is placed within its focus, a virtual, erect, and magnified image of the object is formed at the least distance of distinct vision from the eye held close to the lens.
