Development of the Compound Microscope

The compound microscope is one of the two varieties of modern microscopes (another being the stereo system). It is called compound as it uses more than one important optical part. The compound microscope uses objective lenses and the eyepiece to offer you a better view of the specimen.

A Brightfield Techniques is one wherein you just need to use one of your eyes to look through the eyepiece. Today, you don’t find a monocular microscope .

If you know of someone using one, please tell them that the world has updated. Tell him/her that there is already a better way of enjoying the micro-world – and that’s through the binocular compound microscope. In actuality, there’s a better item on the list, and that is called the trinocular microscope.




Since no ordinary human being has three eyes, the next part isn’t intended for your third eye. Rather, it can be used by another viewer – your teacher, perhaps -to view the identical specimen that you are trying to examine. Alternatively, the third port can be used for a camera (video or still).

Working Together

As stated earlier, the compound microscope is powerful because of the use of two optical components. Let us examine what each part means, and what it is used for:

  1. They are mainly utilized to collect light from the specimen. A compound microscope usually includes 3 to 5 objective lenses, each having a different degree of magnification. You can also click, if you are interested in buying uSight-2000 Microscopes.

The objective lenses are held together by the nose piece. By rotating the nose piece, you can select which objective lens to use.

  1. The eyepiece. This is the part where you put your eyes on to get a clear view of the specimen being analyzed. This is cylindrical in shape. The eyepiece, also referred to as the ocular, is in fact a lens.

By using both optical mechanics, the compound microscope is seldom restricted in regards to magnification. Imagine, you have a lens close to your eyes (the eyepiece) to help you see the specimen, but you also have different objective lenses! Certainly, viewing one specimen has never been so clear.

Still, there are a lot more terms associated with the microscope aside from compound and stereo. If differentiating both – add to that binoculars and trinoculars – is mind-boggling, how much more should you add a metallurgical, a study and a fluorescent microscope on the list? Now, that seems like plenty of work.

You’d surely remember all the terms as soon as you’ve dedicated a significant amount of time studying them. Meanwhile, just focus your attention on the compound microscope: it’s the type that uses two optical parts to supply you with better total magnification.
