A Handheld Digital Microscope USB Typeis a low-powereddigital microscopewhich connects to a computer, normally via aUSBport. They are widely available at low cost for use at home or in commerce. Their cost varies in the range of tens to thousands of dollars. In essence, USB microscopes are awebcamwith a high-poweredmacro lensand generally do not use transmitted light, but rely on incident light from in-builtLEDslights situated next to the lens. The light reflected from the sample then enters the camera lens. However, the camera is usually sensitive enough not to need additional lighting. As the camera attaches directly to theUSBport of a computer, eyepieces are not required and the images are shown directly on the monitor.
They usually offer modest magnifications (about 1× to 200×) without the need to use eyepieces at very low cost, at least compared to conventionalstereomicroscopesfor example.The quality of the final image depends on the camera capacity ormegapixelsavailable with the system, varying from 1.3 MP, 2 MP, 5 MP and upwards, as well as operator skill and illumination quality. Bothstill imagesandvideoscan be recorded on most systems. The capacity of most USB microscopes is similar to that of mostcamera phonesof about 2 megapixels.
Empowered with USB 3.0 interface, the Dino-Lite Edge 3.0 series, including AM73115, AM73515 deliver exceptional sharp and fluent images. With compression eliminated, the 5MP Edge.3.0 series can reveal the finest detail to fully unleash the power of the Edge optics. Thanks to USB 3.0, the 5MP Edge 3.0 series is capable of providing 15FPS at 5MP or 45FPS at 1.3MP resolutions, allowing the unit to be used in a more demanding application
The Dino-Lite Edge 5MP series, including AM7115, AM7515, and AM7915, were designed to meet the needs of higher image resolution, superior image quality and greater flexibility in use. The 5MP Edge series retains all the features and options available in the 1.3MP Edge series, but added with Flexible LED Control (FLC) feature and new generation metal-housing design. Thanks to low-loss compression, the 5MP Edge series is able to deliver crisp image quality at moderate frame rate over USB2.0.
