The EO Precision Zoom Lenses are ideal for inspecting small details, especially electronic components. All lenses feature a robust, anodized aluminum housing, as well as an incremental (or detented) zoom for easy integration. With a working distance of 195mm, the 0.37X – 2.23X lens is ideal for applications requiring a large object standoff or field of view. The 0.7X – 4.5X lens features a working distance of 92mm and is available in coaxial or standard models. In addition, all 0.7X – 4.5X lens models feature an option for an inner focus to allow them to image a large depth of field without moving the whole lens or object under inspection.
