Steiner 20×80 M2080 Military Binoculars

Description

Conduct long-range tactical surveillance and border reconnaissance using the Steiner 20×80 M2080 Military Binoculars high-magnification Porro prism optical system. Combining high-power 20x magnification with massive 80mm objective lenses, this heavy-duty military optic delivers a 174-foot linear field of view at 1000 yards (57.8m at 1000m), an actual angle of view of 3.3 degrees, a 4mm exit pupil, and 15mm of eye relief for resolving distant vehicle markings, perimeter intrusions, and coastal vessels during stationary outpost watches.

The optical configuration features high-index BaK-4 Porro prisms mounted in a shock-absorbing floating silicone suspension, paired with Steiner fully multi-coated military optical elements that maximize light throughput and contrast in poor visibility. Measuring 29.5 by 22.6 by 9.9cm (11.6 x 8.9 x 3.9 inches) and weighing 1930.6g (68.1 oz), the housing is fabricated from impact-resistant Makrolon polycarbonate and aluminum alloy, wrapped in oil-and-acid-resistant NBR Long Life rubber armoring. The chassis is pressurized with dry nitrogen gas and O-ring sealed for submersible waterproof reliability down to a depth of 5m (16 feet). Adjustments center on the Steiner Sports-Auto Focus individual eyepiece focusing system with a 197-foot (60m) close focus limit, an extensive -5 to +5 diopter compensation range on each ocular, fold-down rubber eyecups, an interpupillary distance scale from 56mm to 74mm, and a built-in central tripod mount interface for stabilized glassing.

Key Features of Steiner 20×80 M2080 Military Binoculars

Engineered to meet rigorous defense specifications, this 20×80 Porro prism binocular combines extreme resolving reach with high optical contrast. Its Sports-Auto Focus system delivers constant focus from 60 meters out to infinity once calibrated to the observer eyes. The nitrogen-pressurized Makrolon housing, floating prism suspension, and oil-resistant NBR rubber armoring ensure mechanical reliability in severe desert, maritime, and mountain environments.

80mm Objective Lenses & High-Power Porro Prism Optics

The 80mm objective lenses gather extensive photon volume, working with high-index BaK-4 Porro prisms to generate a balanced 4mm exit pupil that pierces shadows and low-contrast atmospheric haze. Steiner broadband military multi-coatings maximize transmission across the visible spectrum, suppressing reflections and optical flare when observing distant ridgelines into the sun. The Porro prism layout maintains three-dimensional spatial separation and depth perception, allowing operators to distinguish camouflaged subjects against complex topographical backgrounds.

Makrolon Polycarbonate Body & Sports-Auto Focus Mechanics

The Makrolon chassis withstands severe mechanical shock and structural impacts up to 11 Gs, utilizing a flexible silicone mount that shields internal prism alignments from severe handling. Textured NBR Long Life rubber armoring resists degradation from petroleum products, saltwater, and extreme solar heat while providing a firm grip in freezing temperatures. The Sports-Auto Focus system allows operators to calibrate each eyepiece diopter ring from -5 to +5, keeping targets from 60 meters to optical infinity in continuous sharp focus without refocusing on moving targets.

• Sports-Auto Focus individual eyepiece dials providing set-and-forget focal sharpness to infinity
• Nitrogen-pressurized Makrolon housing with floating prism mounts resisting extreme shocks and water pressure
• Integrated central tripod mounting interface enabling vibration-free extended observation shifts
