Compound microscopes are also known as compound light microscopes, light microscopes, or biomicroscopes. They are used to look at specimens not visible to the naked eye, such as blood cells.

The compound microscope has many advantages over the simple microscope. Firstly, it achieves a high magnification because it uses two lenses instead of one. Secondly, it comes with its own light source. Finally, a compound microscope overcomes the limitations of resolution.

BEST COMPOUND MICROSCOPE COLLECTION FOR YOU

What is a compound microscope?
The compound microscope is an instrument for viewing magnified images of small samples on slides. It can achieve higher magnification and reduced chromatic aberration than other microscopes by using two or more lenses in the objective and eyepiece.

The objective or objective lens sits on an objective turntable with a shorter focal length, close to the target specimen. It collects light and focuses the image of the object into the microscope. A second lens in the eyepiece has a longer focal length and further magnifies the image.

How do you choose the suitable compound microscope for yourself?
Here are some factors you should consider to buy the best:

  • Composite VS Stereoscopic
Are you looking at larger 3-dimensional objects such as leaves, insects, coins, flower petals? Or are you interested in checking for defects in electronic parts? Then you are most likely to be in the market for a stereoscope.

To view prepared slides such as pond organisms, pollen, skin cells, or bacteria, you need to buy a compound microscope.

  • Student microscope VS laboratory microscope
Do you want to use the microscope in the classroom or as an educational aid? Or do you work in a clinic or laboratory and need to look at blood samples every day? Read the two categories below to see which one is closer to your needs. It will give you a good idea of the price range you want to view.

Student Microscopes:

As the name suggests, these microscopes are typically used for educational purposes and are primarily for K-12 settings. However, you can also consider these to be amateur-grade microscopes. Student microscopes are inexpensive microscopes, usually priced between $50-$400.

While they won't give you the same performance as a laboratory microscope, they can meet almost any teaching or hobby-related need.

Laboratory microscopes:

While laboratory microscopes are commonly used in the laboratory, you can also consider them professional-grade microscopes.

These microscopes offer upgraded performance but at a higher cost. Depending on the characteristics and quality of the components, laboratory microscopes often range in price from $500 to several thousand dollars.

  • Microscope Heads
The head, or the top of the microscope where the eyepieces are located, comes in three different compound microscopes: monocular, binocular, and trinocular.

This may seem like a daunting string of terms, but they refer to the number of eyepieces a microscope has. A monocular microscope has only one eyepiece. A binocular microscope has two eyepieces. And a trinocular microscope has three.

Monoculars are the cheapest of the three options and tend to be found on student microscopes. As they use only one eyepiece, monocular microscopes give you a more limited field of view than binocular setups.

Binocular lenses are often found on laboratory-grade microscopes. They are more comfortable to use for long periods as they allow you to use both eyes equally, thus reducing eye strain. If you use this microscope every day, it is worth spending the extra money on a binocular microscope.

The final microscope arrangement is trinocular. It is most commonly used for microscope cameras.

  • Magnification
Magnification is an essential aspect of a compound microscope. We can determine the magnification of a compound microscope by looking at two factors: the eyepiece's magnification and the objective lens's magnification.

When buying a microscope, you need to ensure that the microscope is at the level of magnification required.

  • Illumination
We recommend that you do not purchase a compound microscope that lacks illumination.

LED or fluorescent illumination is standard on the cheapest compound microscopes, and we strongly recommend that you purchase a microscope with one of these two forms of illumination.

Compound microscopes are equipped with a built-in diaphragm that allows you to control the amount of light directed at the sample. Some oscilloscopes have disc diaphragms that operate as wheels with different sized apertures, which you can rotate to adjust the light. Much superior to the disc aperture is the iris aperture, which allows an unlimited number of illumination configurations.

Most oscilloscopes also have a spotting scope to control how the light hits the sample. If you intend to view at high magnification, you should look for a removable spotting scope allowing you to adjust the light most efficiently.

Having read this guide, we hope you now have an idea of the type of microscope you want to buy.

How to use compound microscopes correctly?
  • Focusing microscopes
First, turn the turntable (dial) on the compound microscope so that the lowest power objective "snaps" into place. The lowest power objective is the shortest objective. This objective is the easiest to focus and center the image in the field of view.

Looking at the objective and stage from the side, turn the coarse focus knob to move the stage up towards the objective. Move it as far as possible without touching the slide.

Now look through the eyepiece and adjust the illuminator and aperture until a maximum, comfortable light level is achieved.

Slowly turn the coarse adjustment to move the carrier down (away from the slide). Continue until the image is in broad focus. Turn the fine adjustment knob as needed to obtain perfect focus.

Move the microscope slide until the image is in the center of the field of view. Then readjust the illuminator or aperture to obtain the sharpest image.

After obtaining a clear image, you should change to a higher magnification objective with minimal focusing. If you cannot focus on your sample, repeat the above steps and work from one objective to another until a higher magnification objective is in place.

  • Care and maintenance of the microscope
If properly cared for, your compound microscope will last a lifetime.

When you have finished viewing, lower the carrier stage, snap the low magnification lens into place, and remove the slide.

Turn the microscope off when not in use.

Avoid touching the glass part of the lens with your fingers. Only use special lens paper to clean the lens.

Dust is the microscope's number one enemy, so always keep the microscope covered when not in use. If the microscope is not used for an extended period, place the microscope in its case.

How does a compound microscope work?
Microscopes are tubes filled with lenses, curved pieces of glass that bend (or refract) the light passing through them.

The simplest microscope is a magnifying glass made from a single convex lens, usually magnified about 5-10 times. Microscopes used in homes, laboratories, and schools are compound microscopes. They are with at least two lenses to produce a magnified image. There is a lens above the object (called the objective) and another lens near the eye (the eyepiece or ocular).

Each of these may consist of a series of different lenses. Most compound microscopes can magnify 10, 20, 40, or 100 times, but specialist microscopes can magnify 1000 times or more. For greater magnifications than this, scientists often use electron microscopes.

What are the parts of compound microscopes and their functions?
Essentially, a compound microscope consists of optical and structural components.

Structural components:

A compound microscope's three essential structural components are the head, the arm, and the base.

  • Head
houses the optical components of the upper part of the microscope.

  • Base
supports the microscope and contains the illuminator.

  • Arm
attaches to the base and supports the microscope head. It is also used to carry the microscope.

Optical components:

The compound microscope has two optical systems: the eyepiece and the objective lens.

  • Eyepiece
It is what you see at the top of the microscope. Typically, the standard eyepiece has a magnification of 10x. Eyepieces of different magnifications are available, usually 5x-30x.

  • Eyepiece tube
It holds the eyepiece above the objective lens. Binocular microscope heads usually contain a diopter adjustment ring for inconsistent vision in one or both of our eyes. Monocular microscopes do not require a diopter. Binocular microscopes can also be rotated (interpupillary adjustment) to accommodate different distances between different people's eyes.

  • Objective lens
They are the primary optical lenses on a microscope. They range from 4x to 100x and usually include three, four, or five lenses on most microscopes. The objective lens can face forward or backward.

  • Nosepiece
Accommodates the objective. The objective lens is exposed and mounted on a rotating turntable to easily select different objectives. Standard objectives include 4x, 10x, 40x and 100x.

  • Coarse and fine adjustment knobs
are used for focusing microscopes. They are increasingly coaxial knobs - that is, they are located on the same axis as the external fine focus knobs. Coaxial focus knobs are more convenient because the viewer does not have to fumble with the different knobs.

  • Stage
It is the position where the sample is placed. The mechanical stage is useful when the fine movement of the sample slide is needed at higher magnifications.

  • Stage Clips
Used when a mechanical stage is not available. The viewer should move the slide by hand to view different parts of the specimen.

  • Aperture
It is the hole in the stage. The base (transmitted) light reaches the stage through it.

  • Illuminator
It is the light source for the microscope, usually located at the base of the microscope.

  • Condenser
It is used to collect the light from the illuminator and focus it onto the sample.

  • Iris diaphragm
Most high-quality microscopes include an Abbe focusing lens with a variable diaphragm. In combination, they control the focus and amount of light applied to the sample.

  • Spotter focus knob
Move the spotting scope up and down to control the focus of illumination on the sample.

How would you calculate the total magnification of a compound microscope?
To calculate the total magnification of a compound light microscope, multiply the eyepiece's magnification by the magnification of the objective lens.

For example, the total magnification of a 10x eyepiece and a 40x objective is 400x. The maximum total magnification of a compound light microscope is 1000x.
