Designed to take up where most viewers leave off - viewing side-by-side (parallel) stereo pairs, larger than 3-1/2" x 5". Ideal for viewing images on TVs, computers, pads, and even a side of a barn, easily up to 14 feet away, or even more. A viewer with plano lenses and mirrors, and no convex lenses, the Stereo Wide-View Viewer has no focal length. Everything is in sharp focus. No matter how big your images are, moving back brings the entire stereo pair fully view-able in the viewer, and always in focus. Made of black, opaque, non-reflective plastic, it is light weight and allows no extraneous light to enter the viewer. A sliding lever allows you to toe-in or toe-out the internal mirrors for both eyes simultaneously. The Stereo Wide-View Viewer even has sliding levers for septum extension and retraction to better frame your image proportions. Front non-reflective, removable for cleaning, glass panels protect the internal front surface mirrors. Complete with folding eyeglass temples for "hands-free" viewing, the temples can easily be removed and your Stereo Wide-View Viewer is not a "hand-held" viewer. There is even a tripos scocket at the bottom for mounting on a tripod or stand.
