The Vixen Artscope H4x12 BLUE Monocular is an extremely handy and versatile monocular, designed especially for enjoying your day viewing art at the museum. With a 4x magnification, this monocular provides an 11.5° degree field of view, and can focus down to 20cm (7.9") to get a detailed close-up view of the object under inspection. Three layers of anti-reflection coatings provide a bright, clear image, and long 15mm eye relief allows eyeglass wearers to see the entire field of view with their glasses on.
