The 200X USB Microscope Wand is about the same size as a pencil. The great news is that you can hold the USB microscope in your hand and magnify all kinds of small objects like serial numbers, coins, stamps, and display them on a computer screen. The 7mm optics provides 10X to 200X magnification while a built in LED illuminates the items. You can use the manual focus to sharpen the image. To power up the USB wand, just plug into your computer using Windows 7, Windows Vista, or Windows XP while showing the item on the screen.
