Usb Microscope: What are the Factors to Consider WhenPurchasing a Microscope

Stereo Microscope 101 A microscope is an instrument for viewing. It is mainly used in examining objects which are

too small for the eyes. This instrument is usually used in scientific research and in other fields

which deals with viewing and examining microscopic objects. For instance, the equipment is

very common in studying living organisms because these organisms have biological makeup

which are impossible to view without using an advanced viewing apparatus like a

microscope.

History

The first ever microscope was developed in the 1500s when glasses from telescopes were

used to view small objects. Galileo also contributed in the development of microscope which

was later referred to as the compound microscope. Meanwhile scientists Robert Hook and

Antonie Van Leeuwenhoek were the first people to use the instrument in viewing biological

objects and this help popularized the instrument further. After that, there were many

scientists who followed their path and this helped modernized the instrument further more

when manufacturers began modernizing the microscope. Today, microscopes have been

modernized to be used in different fields. There are now microscopes which can be used at

home while there are microscopes which can be used in advanced research.

What to Consider When Buying a Microscope

When purchasing a microscope, it is important to approach it with caution. After all, these

instruments are quite expensive to procure and maintain. When buying, consider your needs

first. This will help you avoid purchasing the wrong apparatus. For example, if you are to

examine leaves, bugs, rocks, and gems, this calls for a basic microscope. In this scenario the

perfect choice will be a stereo microscope. For more advanced research, high end

microscopes which are capable of high levels of magnification is the right instrument for this

particular need.

In addition to your need, features or components of the instrument is also important to

consider especially if you have a particular feature in mind. For instance, there are

microscopes which can be connected to personal computers via USB. This is very

convenient if you want to review different objects you have examined under the USB

microscope because you can take images and store them in your PC.

Finally, ensure that the instrument is durable Since it is an investment, it is only normal to

seek an instrument which could last long. In addition, it is very expensive to purchase too.

However, since wear and tear is usually expected in most things, it will be nice if the

instrument comes with a warranty from the manufacturer

Purchasing a microscope can be a daunting task especially to the uninformed which is why it

is very important to read and study the concept and features of a microscope. Today, there

are so many types of microscope in the market. By studying the basics of microscope and its

function, will be the only time one can purchase the right instrument.

Below is an overview of topics which you will encounter when purchasing a microscope.

Read and understand them in order to make the right purchase.

Compound or Stereo

Compound microscopes are used in advanced applications due to the high levels of

magnification it provides. Usually specimens examined in this type of microscope include

blood samples, bacteria, and other small specimens. A compound microscope can have 3 to

5 lenses. These lenses can magnify objects up to 100x.

Stereo microscopes are used in viewing leaves, rocks, gems, and insects since these objects

are not really small compared to specimens viewed in compound microscopes. In other

words, a stereo microscope is a basic instrument capable of magnifying objects up to 40x;

the lowest can be 6.5x.

Quality

It is important to take into account the quality of the instrument. This is to avoid spending

huge money on mediocre instruments. Usually German and Japanese brands are the most

sought after because the construction is really excellent but the downside is they are quite

expensive to own. If you have limited budget, you can still find affordable instruments with

quality. However, expect less features on these ones since you are only paying a fraction of

the cost of a high end microscope.

Apart from the overall construction, it is important to consider the optical quality as well.

Objective lenses and the eye pieces must be reliable so as to view the images properly. An

achromatic lens is quite good since it can correct colors as well as produced an enhanced

image. However, there is a much higher lens than the achromatic called plan objectives and

this is used in advanced applications because they produce quality and flatter images.
