The MicroFlip MP-250 100-250x Pocket Microscope from Carson is a powerful magnifying tool with reliable LED illumination that can be used at home or in the field. It is compact and portable with an adjustable magnification between 100x and 250x to reveal the details normally hidden from sight. Place your specimen or a slide under the lens and open up a new world of microscopy, and with your smartphone mounted on the included clip you can capture photos or video and share with your friends. Adding to its usefulness, the microscope has a built-in ultraviolet flashlight that will fluoresce specimens ranging from scorpions to saliva to counterfeit currency and more. The MP-250 runs on one user-supplied AA battery and comes with a starter slide.
