The USB microscope is one of the reasons why invention is a good thing.  It is the latest take on the evolving technology related to microscopy, providing higher resolution images and convenient use.  This is one of the best high-end microscopy that hobbyists and students can use and is also a very useful and efficient instrument for professionals.  When selecting a USB microscope, there are certain key features to consider.  These include:

Magnification
A USB microscope is equipped with a combination of lenses that are capable of producing magnifications ranging from 1x (normal view) to 200x.  These magnifications are often enough to view solid materials for flaws during quality inspection and observing microorganisms as part of a science lecture or research.  When selecting a USB microscope, remember that the optical system is more often the most important feature to consider.  Determine whether you will only be using the equipment for low power magnification work or if you will need higher magnifications for the observation of extremely minute objects or specimens.

Capability to produce high resolution images
One of the main concerns in the use of microscopy is the production of the image, especially at high magnifications.  An advantage of the USB microscope is that it takes advantage of digital technology to provide features such as image contrast and white balance to produce crisp and clear images of a specimen.  Even at high magnifications, these images can be maintained, especially with the use of automatic image balancing capability.

Choose the resolution that is appropriate for your need.  A USB microscope with a higher resolution is of course more appealing but if your work involving microscopy only requires low magnification, the feature will not be maximized.

Adaptability/Connectivity
An advantage that the USB microscope has that traditional optical microscopes don’t have is its adaptability for use with other equipment, such as a computer, digital camera or video camera.  USB microscopes come with at least one port that may be connected by cable to a computer so that images may be uploaded and viewed.  Images can then be stored safely, maintaining their high resolution.  As electronic files, images can also be manipulated or edited with the use of appropriate software and sent via e-mail.  With a digital camera, excellent quality images and even videos can also be captured.

Since USB microscopes can be connected to other equipment, they can also be used for lectures and presentations.  Instructors and teachers can upload images using the computer and show them through a projector or monitor screen.  Specimen images can also be shared remotely using a web cam.  This is an important feature of the USB microscope, so in the process of selection, determine if the instrument is compatible with the tools you already have or if it will still require you to purchase software and hardware just to be able to use it.

Flexibility of use
The digital USB microscope has evolved from the bulky and heavy steel model to the convenient handheld instrument that is portable enough to be carried in a small purse or even the pants pocket.  These small gadgets are equipped with useful magnification (typically ranging from 20x to 200x), LED lighting, standard high resolution and a USB 1.1 or 2.0 port.  A few models are already equipped with 1.0 to 1.3 megapixels.  Look at the kind of connectivity the instrument has to determine whether it will work with other gadgets you might want to use, such as a video camera or computer.  You might also want to see if the microscope will work with optional accessories, such as a C-mount adapter, which will allow you to use it with a digital camera for image capture.  Check what type of software the instrument uses for image editing.

Reasonable cost
A simple digital USB microscope setup equipped with a hub or webcam can be bought at about $200.  This will include low and high power objective lenses ranging from 30x to about 600x.  Resolution should be at least 640 x 480, enough to produce a sharp image of the specimen.  If higher resolutions are desired, a more expensive instrument may be selected.  Some models are also more costly, offering a combination of portability and functionality that is difficult to top using similar gadgets.  Prices also vary significantly, ranging from $250 to about $900, depending on the manufacturer, model and features.

When selecting a USB microscope, it’s important to remember that the more sophisticated the features are, the more expensive the equipment.  Consider if the features will be useful for your particular field of study or interest.  Otherwise, you might be buying an instrument with functionalities that will not be maximized.

Uses of the USB microscope
The USB microscope can be used in a variety of fields, including medicine, biology, forensics and crime scene investigation, gemology and jewelry making and education.  The flexibility of its magnification power can be used for minute parts assembly, evidence examination and comparison, quality control of components and even image capture.  They are also an excellent choice for hobby use and are becoming increasingly popular among students and gadget enthusiasts.
