The Lighthouse Phonescope slips over the camera lens on smartphones and turns your smartphone into a powerful digital microscope. Simply clip it onto your smartphone (it easily slides on and off). It will not scratch the smartphone display. In place, it instantly captures high quality images and videos using the camera system in your smartphone. Take large close-up photos of coin details using this lens and your smartphone. The precision macro lens has up to 60x magnification. It works with iPhones and virtually all other smartphones. It also works well as a reading aid. No batteries required.
