Microscopes

1. When shopping for a microscope, be sure you know what you really need. Consider features that are must-haves and those that are preferences. Think about magnification power, lens type, lighting, and price.

2. We recommend purchasing a microscope that is built using a sturdy metal alloy. Some other materials, such as plastic, can be more convenient to transport, but won't be as durable or long-lasting.

3. Choose your light source by thinking about your viewing needs. Most come with tungsten, fluorescent, or halogen bulb systems. Fluorescent lights tend to cost more, but they produce less heat and offer brighter illumination.

4. If you're looking for a microscope for children, be sure to purchase a model with easy-to-use controls, low magnification, and one eyepiece for viewing. Most beginner microscopes also include an illumination mirror.

5. The objective lens is the most essential component of a microscope. This is what collects and projects light into the machine and onto the specimen. While lens magnification varies from 1x to 160x, the most common, practical range is between 4x and 100x.

6. If you plan to view small objects, such as cells or bacteria, then a compound microscope is what you need. This machine uses a single light source, features low-depth perception but high resolution and magnification (ranging from 40x to 1500x and up).

7. Researchers interested in fossils, insects, or dissection will want to use a stereo microscope. These machines use two light paths, allowing observers to see specimen in 3D. They feature high depth perception and good zoom capabilities, but also have low resolution and magnification.

8. Microscopes of today range from basic to cutting-edge. Our selection features a variety of all types, including digital microscopes, phase contrast microscopes, electron microscopes, and polarizing microscopes.

9. A digital microscope combines the functions of a traditional microscope with a digital camera. Most of these systems allow users to view specimens on a computer monitor or display screen, which makes for easy viewing and dynamic group learning environments.

10. Don't forget about microscope accessories to complete your viewing experience. You'll want to purchase slides, dyes, and cover slips to prepare specimens, and colored filters to help you see them. Before you choose your microscope, take note as to whether these items are included.
