Binocular Microscope: Parts, What Is It For, What Is It

The binocular microscope is part of the advancement of the common microscope invented by a Dutch eyeglass manufacturer at the end of the sixteenth century. Light microscopes use lenses and light to magnify images.

Although a magnifying glass technically qualifies as a simple light microscope, today's high-powered or compound microscopes use two sets of lenses to give users a much higher level of magnification, along with greater clarity.

📌 What is a binocular microscope?

The binocular microscope is an instrument used to obtain an enlarged image of small objects and reveal details of the structure that cannot be distinguished otherwise. Binocular Microscope is a microscope with a head that has two eyepiece lenses.

Today, the binocular microscope is typically used to refer to compound or high-power microscopes where the two eyepieces see through a single objective lens.

⭐ What are the parts of a binocular microscope?

Are two eyepieces, which they provide a better image and a lens, which can slide down to improve the clarity of the image, as needed. These are their part:


The double binocular eyepiece it contains the microscope lenses and gives the user a magnification secondary of the "target" or the object being viewed, usually a sample contained on a slide.

Mechanical stage

The mechanical stage holds the object, or the specimen slide samples, underneath of the display target and allows the sample to be moved to the left, to the right, back and forth for examination.

Nasal mask and objective lenses

The nasal bridge contains several rotating objective lenses, usually three, which enlarge the image of the object on the stage below.

Capacitor and lamp

The built-in lamp in the base provides light for the viewing area. The light from the lamp passes to through the lenses of the condenser, which focuses the light on the area of observation of the microscope.

Microscope Tube and Prisms

The microscope tube supports the double eyepiece lenses and the multi-light refraction prism of a binocular microscope - the light is divided and directed to the eye lenses binocular.

Rack Stop

This function determines how far the stage can go. Adjusting the zipper stop is useful to prevent the slide from coming too close up and hitting the objective lens.

Normally, this setting it is adjusted at the factory, and it is only necessary to change the zipper stop if your slides are exceptionally thin and you cannot focus the it shows higher powers.


Where the eye. In addition, they connect the eyepieces to the objective lenses.


The bottom of the microscope: what the microscope is on.


Structural element that connect the microscope head to the base.


The flat platform that supports the slides. The stage clips keep the slides in your place. If your microscope has a mechanical stage, the slide will controls by turning two knobs instead of having to move it manually.

One knob moves the slide left and right, the other moves it back and forth.

🔹 Binocular microscope price

A binocular microscope it is not very expensive and can be purchased at affordable prices. This is an instrument ideal for schools and universities to help students with their study.

There are models that by its characteristics can cost about € 40, not counting the expenses in fact, these would be the most suitable for students and children.

Other more sophisticated models, with different functions and features, can exceed € 400.

Who invented the binocular microscope?

It is still unclear when the first microscope was invented and to whom the invention was attributed. The general opinion is that a Dutch eyeglass manufacturer by the name of Zaccharias Janssen (1585-1632) invented and built a microscope between 1590 and 1595.

🍀 Difference between binocular and trinocular microscope

A binocular microscope it has two eyepieces to see the sample. Binocular microscopes are more comfortable to look through for extended periods of time that a monocular microscope (with a single eyepiece).

A trinocular microscope it has two eyepieces like the binocular, but it also has a third tube eyepiece to connect the microscope camera.

When connecting a camera to the microscope, a C-mount adapter is used to connect a microscope camera, or certain point-and-shoot consumer digital cameras can be connected using a microscope camera adapter.

👉 Buy binocular microscope

You will need a microscope compound if you are looking at "smaller" samples as samples of blood, bacteria, pond scum, aquatic organisms, etc. The reason is that such specimens require greater powers of magnification to be able to see the detail.

For this reason, an compound microscope is also known as a high-power microscope.
Typically, a compound microscope has 3-5 objective lenses ranging from 4x-100x. Assuming 10x eyepieces and 100x objective, the total magnification would be 1,000 times.

Microscopic compounds are also integrated systems in the sense that the body and the microscope base form an integrated unit.

When considering a compound microscope, you will also need to decide if you want a monocular, binocular or trinocular. That is, a microscope with one, two eyepieces or one with two eyepieces and a third trinocular port.

The basic variables:

1. Magnification: Microscopes monoculars work efficiently up to 1000 times the total magnification. For higher magnification levels, a binocular microscope is required.

2. Comfort: Most of the people find binocular microscopes more ergonomic and easy to use than the monoculars. Young children, on the other hand, find that the
monoculars are easier to use.

3. Price: While the price ranges overlap, typically a monocular microscope is the the least expensive type of microscope, the trinocular being the most expensive.

4. Application: Most monocular microscopes do not include a mechanical stage, which is useful for more sophisticated applications. Most binocular microscopes include a mechanical stage. A trinocular microscope is typically used when a third (trinocular) port is required for microphotography.
