Dino-lite am7115mztw edge handheld digital microscope with polarizer, dual focus, 5mp, 2x – 50x the am7115mztw dino-lite edge delivers 5mp image quality with wide field-of-view (wfov) and depth-of-field (dof), which makes it ideal for macro viewing applications. With a working distance of more than 1cm from the target, once in focus, rotating the knob will receive another focal point, and thus effectively zoom in the image optically. This offers the capability of looking into more detail while enjoying a larger field of view. The freely adjustable polarizer helps to reveal more detail or to enhance the contrast on the surface by reducing or eliminating the reflections. This model includes the adaptable cap design, a detachable and interchangeable front cap design used in the dino-lite edge series. Different caps have been developed for more applications. Simply removing the cap would yield more working distance which brings added convenience in the higher magnification range, or have better accessibility to the full range of magnification.
