This Carson MicroMini 20x Pocket Microscope can make a handy addition to any outdoor gear. With its longest dimension at under 2 inches, this magnifying tool can fit into the tiniest of pockets. Despite its size, it muscles up a 20x magnification power and packs three bright LEDs for illumination (two white light and one UV), each of which has a special function. For making close-range, table top observations, use the sliding switch on the side to activate a white LED that is located closest to the objective lens. This LED shines light on objects that are placed under the scope in a tabletop operation mode. For using this optic as a magnifier, push the same sliding switch to activate a long-range LED illuminator. This LED is located farther away from the objective lens and casts light at objects that are from a few inches to a few feet away from the microscope. The third LED, which can be turned on via a round pushbutton, shines ultraviolet light and can be used to authenticate oil paintings, antiques, and banknotes, or to study otherwise invisible objects or traces that exhibit fluorescence under UV light. This miniature microscope also has a knurled wheel for focusing on the side and a key chain.
