Assaulted and Blasted but Never Defeated

Optics Technology

The armored vehicle, serving in Iraq, was hit with an IED that blasted and burned everything but the men inside. They got safely out, but much of their gear was destroyed—except for these Steiner military binoculars. They came out chared and misshapen, armour and chassis disfigured by fire and impact—but still working, lens and prism systems intact. The men were suitably impressed, but not really surprised. Steiner optics are world-renowned for ferocious toughness. Like those who use them, they may take the occasional beating, but they are never defeated.

Built for Abuse

Battle-proven Steiner lenses and prisms are built into unbreakable, rubber-armored Makrolon® polycarbonate binocular housings, and seamless, high-strength alloy scope tubes. Then purged, sealed and shielded to be fog-proof, waterproof, impact resistant and immune to extremes of every kind. Now, and for lifetimes to come.

Designed for Comfort

Binoculars rest comfortably in the palms, with rubberized housings and hand-friendly ridges, curves and pads for intuitive use. Scopes have adjustable illumination, oversized knobs, and positive sound/feel feedback for easy settings and repeatable accuracy. Every detail is ergonomically perfect. Because the world never is.

Crafted to See Better, Not Just Further

For over 65 years, Steiner-Optik in Bayreuth Germany, has set the bar in premium long-range optics. Over 460 exacting steps ensure rigorous quality throughout design and manufacture. Relentless innovation creates technologies like the N2 injection™ system, laser protection filters, Steiner nano-protection® and Diamond-night™ lens coatings. Constant user feedback, from battlefields to birding, keeps performance state of the art. No optics will serve you better.

100% In-House Optics

Steiner grinds and polishes their own premium lenses and BaK4 prisms, then multi-coats all air-to-glass surfaces with proprietary coatings for unmatched brightness and clarity.

Unerring Precision

After more than 460 high-precision manufacturing and inspection steps, finished multi-coated lenses are assembled into unbreakable Makrolon® polycarbonate binocular housings.

Perfect Coatings

Steiner advanced lens coatings, applied to every air-to-glass surface, have evolved to enhance light so your eyes perceive more contrast and brighter detail, even in low light conditions.

Military Innovations

Porro prism rugged.
Steiner reliable.

Steiner porro prism binoculars are extremely tough and dependable, ideal for military and tactical applications.  The porro system creates a realistic three-dimensional image, with maximum depth of field, for accurate evaluation and targeting.  Even at extremely long distances, the user can clearly see whether one object is behind or in front of another.  With exceptional light transmission, the porro system also provides enhanced clarity in challenging low-light situations.

World class, combat-proven coatings.

All air-to-glass surfaces of Steiner binoculars and scopes are multi-coated with proprietary, cutting-edge formulations of minerals and rare earth compounds that maximize clarity, color and definition. As the one brand that has developed optics specifically for military service, Steiner is committed to giving you every possible edge.

Built for anything.
Anywhere. Anytime.

Steiner mil-spec binoculars and scopes are designed for true battle-field conditions. Rugged lens construction ensures stability even under severe shock and vibration. Unbreakable Makron® binocular housings with stand oils, solvents, heat, cold, sun and saltwater. One-piece nitrogen pressurized 34mm scope tubes are shockproof to 900 Gs. All optics are fog-proof and waterproof, sealed against dust, dirt and moisture. All are immersion waterproof, some to depths of 33 feet. Designed with special forces and expert weaponry input, built to strict milspec demands, Steiner optics exceed the need.

Fog proof, waterproof.
N2 Injection™ System.

Steiner's proprietary N2 Injection™ System pressurizes optics with nitrogen and trace helium. If seals are not absolutely tight, hyperbaric testing reveals escaped helium molecules, the optics are disassembled, and the process is repeated. Fail-safe testing with medical-grade tools ensures absolute quality, positive internal pressure, and zero fogging and water intrusion despite drastic changes, severe conditions, and lifetimes of use.

Advanced laser protection.

Steiner was the first to offer binoculars with laser protection filters. Since our initial research and development, we have gained industry-leading experiences with knowledge in this technology, which benefits all military customers. All our military binoculars can be supplied with laser filter protection, either standard filter (OD 4 / 1064 nm) or one meeting the specific user requirements.

All temperature performance

Steiner Military binoculars are temperature hardened, impact armored and combat ready for any theater in the world. Built for operating conditions from -40° to +176° F., they will deliver consistently sharp, clear, fog-free images, from arctic snowfields to desert heat, jungle valleys to mountain peaks. No matter where your duty sends you, no binocular will serve you better.
