Being resistant to temperature changes not only ensures that the housing will remain a constant temperature, even in cold and wet conditions, but will not experience the expansion and contraction common in metal chassis that can cause the optical elements to move out of alignment over time and preventing the binocular's ability to achieve sharp focus. The chassis is covered in a black rubber armoring that helps to protect it from drops and impacts, and provides a slip-resistant grip.
The compact Schmidt-Pechan prism design corrects the view while allowing for thinner optical tubes versus the more common Abbe-Koenig design. SCHOTT ED glass elements reduces chromatic and spherical aberrations to produce views with true color rendition without halos, diffraction, or distortion across the entire field of view.Zeiss proprietary hydrophobic multi-coated optics sheds dust, dirt, and oils while improving light transmission, color rendition, sharpness, and contrast. Short 5.25 foot close focus distance.
Wide 61° apparent angle of view. 367-foot field of view at 1000 yards. Long 16.5mm eye relief.Impact, corrosion and temperature-resistant fiberglass-reinforce polycarbonate housing.
