Some Basic Types of Microscopes
People might be very familiar with microscopes
, but they might not have enough knowledge about some basic types and basic operations of this laboratory equipment. Besides, people might not notice about the way a microscope works in supporting your vision in analyzing very small objects.
There are three types of microscopes that you can easily find. They are bright field, dark field, as well as fluorescence microscope. The bright field one is the most basic type of microscopes used in many requirements in the world.
When you are using a microscope, you might see some parts that are connected each other to form a single system. The tube of this tool contains an eyepiece that is connected to an ocular or interior lens. Then, the interior lens is connected to an objective lens. This is a certain lens that centralizes and magnifies light that passes through it.
If you choose the cheap one, usually you will have a product with mirrors without any additional supporting features. Meanwhile, choosing professional microscope allows you to get a product with light bulb that helps you a lot to get better lighting. When the light bulb is turned on, the light will pass through the glass above it, the lens, and the ocular into the eyes of the observers.
Meanwhile, the function and the form of the dark field microscope are almost similar to the bright field one. By using a product in dark field type, the contrast between the specimen and the bodies that surround it will be increased. Besides, in this certain type of microscope, the light passes through the lens of condenser to be focused on the sample plate.
The last type is fluorescence microscope. This is a certain device that is used to examine the organic specimens. It relies on the certain specimen to react to a certain wavelength of fluorescent light. Besides, the fluorescent light is typically beyond the capacity of the human eye to see. The light is commonly passed through a focusing lens, and then is passed through the specimen.
Those are some different types of microscope and their systems to help your laboratory activity. Obviously, you can find a lot of options that are offered under several different brands. Find the best one for your needs.
