A light microscope is one of the most popular types of microscopes for looking at images. In the beginning, light scopes were created to see things such as fabric weave and other simple objects.
However, as time progressed, a person named Anton van Leeuwenhoek found ways to create scopes that allowed people to see things that were previously invisible. Today, these microscopes have come a long way but they still use light in various ways to view "invisible" worlds.
One of the most popular types of a light microscope is that of the bright field microscope. These are the most popular in most schools. A bright field microscope aims light through the specimen into the eyepiece, in order to view the objects on the microscope slides.
A student can then use the coarse or fine knobs to adjust their field of view. Unfortunately, these are limited light microscopes and can sometimes distort the image as soon as one begins to see it clearly.
Another type of light microscopes that can be found in many labs is that of the dark field. These microscopes are great for viewing objects that would otherwise seem distorted with a bright field scope, such as cells and pond water.
The small metazoans can easily be seen and distinguished when using this type of scope. The light is reflected by particles on the microscope slide. This allows for a more in depth study at a small cost compared to a scanning electron one.
Choosing a light microscope to look at items can be a daunting task. One has basically two choices and depending on how much or what one wishes to see will determine if a person chooses correctly. Both the dark and bright field microscopes offer great advantages for those who want to see the unseen.
However, if one wants to be more in depth, then a little more money and effort learning about the in's and outs of the scope will be required. The main thing to remember is that science is the backbone of our world, no matter how high tech it has become.
A whole world of information about the light microscope eagerly awaits you from Mike Selvon portal. We appreciate your feedback at our telescopes blog.
