Microscope Boom Stands

Microscope boom stands allow the user to place large objects under the microscope. The stands provide ease of use, as they swing the microscope body toward and away from the items that need to be magnified.

The ball bearing boom stand slides smoothly along the horizontal axis. This horizontal axis can be secured on the vertical post in a number of varying heights.

Above is an example of an electronics inspection microscope system on a boom stand. This microscope system uses a 150w halogen dual arm fiber optic illuminator that provides pinpointed light for viewing printed circuit boards.

The articulated arm microscope stand has several joints that allow the microscope body to be placed in varying positions. This boom stand secures the microscope body in position until it is adjusted. It does not slide on ball bearings the same way that the ball bearing boom stand does.

Measuring with Microscope Cameras

Making measurements with a microscope can be performed using an eyepiece reticle. Another way to perform measurements is by using the software that is included with a microscope camera. The image below was captured with the Lumenera Infinity 1-3 DK3000 3.1 mega pixel digital microscope camera, using the measuring software. The software was calibrated with the microscope and then measurements were made by using the computer.

Image captured at 1000x magnification using a metallurgical microscope.

When using the software to make measurements, the accuracy of the measurement is dependent on the ability to find the edges of what you are measuring. Measurements are made by drawing a line on the image. You can also draw a circle to determine the diameter or radius of the circle, or polygon images.

Magnifying Electronics

Printed circuit boards and small electronic parts can be difficult to view under a microscope because most of the components are not on a flat plane. These images were captured with a Meiji EMZ-5TR stereo microscope and a MC2000 digital camera at 15x magnification.

When viewing electronic parts, low magnification is generally best - anything between 5x - 20x is usually all that is required.

Adjusting the focus will allow you to view different focal depths in the undulating surfaces. Another option is to hold the piece in your hand and slowly move it up and down until the focus is crisp. Many technicians do this as they are soldering small pieces.

USB Microscopes

Digital microscopes, also known as USB microscopes allow you to connect the microscope directly to your computer. The microscope comes with software that when open, allows you to view a live image from the microscope directly on your computer.

USB microscopes allow you to gather multiple students around the computer to see an image, rather than taking turns to view a single image through the microscope eyepiece.

The software included with digital microscopes allows you to capture and save both still images and motion video. You can print images, email them, or put them into a presentation.

The Digital BA210 laboratory microscope is commonly found in Universities.

Digital USB microscopes are made for kids as well. This kids microscope is the DS-2 microscope. Low magnification of 20x and 40x is perfect for viewing rocks, coins, flowers or details on a toy car.

Brightfield, Darkfield and Phase Contrast

The images below are of a spleen and were captured at 400x magnification with the Meiji MT5310 microscope. This microscope has the capability of viewing specimens with brightfield, darkfield and phase contrast.

This image was captured using brightfield. Brightfield microscopy is the standard form of microscopy found in most high schools when using a high power light microscope.

This image was captured using darkfield. Darkfield is similar to back-lighting a subject. This microscopy technique takes the light and diffuses it toward the sides rather than directly through the objective lens.

This image was captured using phase contrast. Phase contrast is often used to view specimens that are the same color as the background they are against. Sometimes rather than staining a specimen, phase contrast will be used to produce similar results.

Low Power Microscopes

Low power or stereo microscopes are great for looking at things you might hold in your hand. These microscopes allow you to view details in objects that you can already see with the naked eye. Sometimes these microscopes will use no light, such as the 185 elementary microscope. Other stereo low power microscopes will have top and bottom illumination, such as the 460TBL microscope.

The amount of things you can view with a low power microscope is endless.

Wastewater Treatment Microscope

Microscope World has several microscopes set up specifically for wastewater treatment facilities. The most important microorganism that wastewater treatment facilities are looking for is bacteria. In order to view the bacteria, phase contrast is utilized.

Image of bacteria captured at a wastewater treatment facility using the DC5-163PH digital phase contrast microscope at 400x magnification.

Protozoa are single-celled animals that are the most abundant animals in the world. Wastewater treatment facilities are looking for these creatures. Different forms of protozoa the wastewater treatment plant may be searching for include: amoebas, flagellates, free-swimming ciliates, and carnivore ciliates.

This image of bacteria was captured with the DC5-163PH digital phase contrast microscope at 400x magnification.

The ability to capture and record images while scanning specimens in wastewater treatment is helpful. The two digital microscopes most commonly used for wastewater treatment are the DC5-163PH and the DMBA310 with phase. If you have any questions regarding phase contrast work please call us at 800-942-0528 and we will be happy to help you select the correct microscope for your needs.

Microscope Project: Mold

Next time you open the fridge and see a moldy piece of bread, cheese or a strawberry, don't throw it out right away. Grab your microscope and learn a little bit first! If you have both a stereo microscope and a compound microscope, you can use each to view the mold.

Starting with the stereo microscope, take a look at the mold. Notice the texture of the mold, it may almost look soft like fabric.

Now take the same moldy food and scrape a small piece of mold off with a knife. Place the mold on a blank microscope slide and place a cover slip on top of it. Using a high power microscope, take a look at the mold again. How does it look different? Can you identify any bacteria? Draw a picture of the images that you see and ask your science teacher to help you identify the cells in the mold.

Identifying Particulate Contaminates

Microscope World often helps customers configure a microscope system for identifying particulate contaminates. For example, the standards for European Pharmacopoeia Section 2.9.19, Method II: Microscopic Particle Count Test require the following:
  1. Binocular Microscope
  2. Eyepiece Reticle (Graticule) for specified type
  3. Stage Micrometer with Certification
  4. Mechanical Stage
  5. Episcopic (Reflected) Light Microscope
  6. External Illuminator with Oblique Lighting
  7. 10x Eyepieces with a 10x Objective Lens
The following microscope system was created to meet these standards. The MT7200 reflected light metallurgical microscope, paired with an IMA/USP counting reticle, stage micrometer (NIST certified), and a LED dual pipe illuminator for oblique lighting.

One of our microscope specialists configured this microscope system to meet specific standards.

What Can I See With My Microscope?

A compound light microscope has a resolution of about 200nm. A light microscope will allow you to view cells that are alive, fixed or stained.

Bacteria (shown above) is an example of one of the smallest cells that can be seen with a light microscope. Animal and plant cells can be viewed with a light microscope as well.

In order to view small molecules or viruses, a transmission electron or scanning electron microscope is needed. These types of microscopes have a limit of resolution down to 2nm.

Hair Science Project

The goal of this science project is to measure hair damage and strength using no hair products and then again after using a variety of different products.

You will need a student microscope with at least 100x magnification. When viewing a single strand of hair, the biological elementary student microscope works well.

Before you begin, find a few friends or family members willing to participate in your science experiment. It is best to use hair that has not been lightened or darkened, as this alters the strength of the hair. Once you have located your subjects, gather a clean strand of hair from each and place it under the microscope. If you can, capture an image of each and label the image with the name, magnification and test # (see example below).

Friend A, 100x magnification, test #1

Friend A, 1000x magnification, test #1

After capturing your images, set the pieces of hair aside in a labeled envelope. Later you will want to pull these out again to test the strength of the hair.

Once you capture the images, have each friend use the same hair care product for a week. Try something that advertises "hair strengthening" or "heals damaged hair". After a week, collect a piece of hair from each person and look at it under the microscope.

Do you notice any difference between the hair from test #1 and test #2? Does the hair care product really make the hair healthier? A damaged piece of hair will have rough edges when viewing it through the microscope. You may want to have the subjects try another week of the hair product and compare a third time.

Finally, take the hair from each session and try to break it by pulling on each end. Do you notice a difference in the strength of the hair that was not treated with any products to those that were?

Did you notice a specific color of hair tended to be stronger than others? If so, you could complete a secondary science project by gathering more samples of similar colors of hair for comparison. If you have great findings from your science project, send us an email, we would love to hear about it!

Nature at 10x and 30x Magnification

Stereo or dissecting microscopes allow you to view nature up close and in detail. Even a simple 20x kids microscope can reveal the stigma of a flower or plant. When viewing items found in nature, a microscope with 10x - 40x magnification is generally best.

This leaf image was captured at 10x magnification,

The same leaf, at 30x magnification.

If you are looking for a good children's microscope that connects to the computer so you can capture and save your nature images, Microscope World recommends the DS2 digital student microscope.

Blood Cells

These pictures were captured with the DC5-163 digital microscope. In order to prepare the blood cells, an employee at Microscope World used a clean needle to prick his finger and placed a small drop of blood on a blank glass microscope slide. A cover slip was immediately placed over the small drop of blood and it was given time to dry. While the specimen was drying, the employee used an alcohol swab to clean his pricked finger and put a bandage on it to keep bacteria out it.

These images were captured at 400x magnification. Notice how many cells fill the field of view at 400x magnification! The larger gray areas are air pockets that were caught between the slide and cover slip.
