The HHD Professional Series Portable USB Microscopes are easy to use, high power scopes. With continuous magnifications from 10x to 280x, it's ideal for quality control inspectors, medical professionals, and scientific researchers in addition to hobbyists and beginners for viewing stamps, coins, bugs, plants, rocks, skin, gems, circuit boards, and more. With the higher power magnifications, you can even view traditional microscope slides under transmitted illumination.
Using the AmScope Software, you can capture your specimens using the built-in 1.3MP camera. Press the shutter to save images and high-resolution video directly to your PC via USB connection. The 8 LED illuminator ensures your specimens are clear and bright. Includes a basic metal stand as well as a gooseneck stand that allow for steady shots and come in handy when viewing at higher magnifications, minimizing shaking and keeping your specimen in sharp focus.
