Unlike others, Tele Vue prisms and mirror diagonals begin life as one solid chunk of metal-which is then continually refined to produce what you see before you now. This is a huge asset because there's nothing within the prism or diagonal which could unscrew and cause a heavy, expensive eyepiece to drop.
Tele Vue's Everbrite diagonals provide whiter, brighter images than any other diagonal. The exotic Everbrite coating is 99% reflective across the entire visual spectrum. Painstakingly applied, the Everbrite is offered in both 1.25" and 2.00" models. The bodies are machined from solid aluminum blocks, ensuring permanent alignment as well as not allowing heavy accessories to unscrew the body from the barrel.
The 60° Everbrite Diagonal is a great addition for anyone interested in birding or general terrestrial viewing. Combining performance with great ergonomics, it is the best combination for use with the Bino Vue Stereo Binocular Viewer and yields images which are upright but laterally reversed.
