The field of application of digital USB microscopes is extremely wide. Collectors, jewelers, watchmakers, scientists use such devices. They are also used in everyday life.
All USB microscopes are small in size. They can be connected to computers, laptops or tablets to transfer and save data.
The set of functions differs from device to device, and when choosing a microscope, you need to be guided by the purposes for which it is purchased: to examine collectible coins and stamps, to carry out minor repairs, or to interest a child in studying biology.
Technical specifications
The main technical parameters to look for when choosing a microscope are magnification range, sensor resolution and frame rate.
A device with a 100-fold magnification is enough for a younger student - this is quite enough to view grains of sand, insects or plant leaves in an enlarged form. Children of middle school age are interested in conducting experiments using a digital microscope; this will require a device with a magnification of 400 times. If an adult needs a microscope for work, the magnification must be at least 500.
Resolution determines the level of detail in the image, so it should be high anyway. The best option is 1600x1200 pixels.
The frequency should not exceed 25 frames per second, if the work will consist in the study of small details. If you plan to record videos, you need a frequency of at least 30 frames per second.
Equipment
A USB microscope must include a camera equipped with an adapter and a disc with the appropriate software.
Along with these mandatory items, the package may include other accessories - for example, a bracket. A microscope mounted on a bracket will not tremble, twitch, therefore, the quality of the frames obtained will be an order of magnitude higher, this detail should not be neglected.
Special-purpose USB microscopes are often equipped with additional accessories. In particular, if the microscope is intended for repairing electronic boards, then the kit may include special clips for them.
USB microscopes designed for scientific research come with all the necessary tools: pipette, scalpel, stirring rod, tweezers, dissecting needle, slides and coverslips, medicine bottles and other accessories.
