This cordless stereo microscope is ideal for the new microscope enthusiast. The simple design provides an easy way to view objects at 20X or 40X magnification. Stereo magnification gives the image a three-dimensional depth, which makes it easier to use tools while using the microscope. A battery-powered LED light illuminates the object, so it can be used anywhere. The SE120 is great for students, stamp and coin collectors, and even repairing small items.
