Smart USB macro magnifier with 5 MP resolution and included stand, which makes it easy for you to examine small details and surfaces on the screen. The macro magnifier has a built-in LED light with 8 diodes and light control, so you can adjust the lighting as needed. With the included stand, you get a slightly larger working distance and lower magnification, while if you use the magnifier directly on a surface, you can easily adjust the magnification and focus with the focus wheel. The magnifier connects to your computer via USB and comes with Windows-compatible software, where you can both view live images and record photos or videos.
