In 1968, the Zeiss Dialyt binocular was introduced and redefined binoculars for generations. This classic binocular features large 56mm lenses for low-light conditions, phase-corrected Abbe-Konig prism and Zeiss T* multi-layer coating for added brightness, and a timeless, robust non-slip design. The Dialyt binocular is ideal for night-time excursions.
