The Eschenbach Mobilux LED Handheld Magnifier is an illuminated handheld magnifier that features bright LED illumination. SMD LED (light emitting diode) illumination provides an alternative light source preferred by many patients due to its distinctly whiter spectrum and longer useful life. This state of the art magnifier includes the Eschenbach Mobase Stand that turns your Mobilux magnifier to a hands free magnifier with ease by inserting the Mobilux magnifier into the Mobase stand. The Eschenbach Mobase Stand has two positions to choose from: the upright position allows for hands-free work behind the lens, such as threading a needle or filing nails. When used in the flat position, users can easily slide their Mobilux handheld magnifier over the reading material. The Eschenbach Mobilux LED Handheld Magnifier comes in 7x magnification. The diopter for the 7x magnification is 28D. The Eschenbach Mobilux LED Handheld Magnifier features a comfortable, ergonomic handle with a large, easy to operate ON/OFF light switch, a battery compartment that uses high quality springs that makes changing the batteries easier (2 AA batteries included) and a slip-on protective case..Specs: Magnification: 7x Diopter: 28D Illumination: SMD LED Lens Type: Aspheric Lens Material:PXM Plastic Lens Size: 1.37 in.
