Dino-lite af4115ztw edge 1.3mp wide-angle wireless-ready digital microscope with flc, 2x – 50x the dino-lite edge 1.3mp af4115ztw is designed for wide-angle macro applications providing a 10x – 50x magnifications with flc. It is designed for wide-angle macro applications providing a 10x – 50x magnification range. It delivers higher image quality with larger field-of-view (fov) 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. polarization can be switched on/off or can be adjusted to offer full or half polarization for controlling glare, revealing more details, or to enhance the contrast on the surface by reducing or eliminating the reflections. the new modular wireless-ready design allows for usb connection or a quick swap to wireless with a wf-20 adapter ( sold separately ) making it a completely cordless and portable microscope.
