Fujinon 10×70 FMT-SX Polaris Binoculars 2022

Description

Mounted on vessel flying bridges and positioned across dark-sky astronomy sites, the Fujinon 10×70 FMT-SX Polaris Binoculars 2022 deliver high-contrast stereoscopic resolution and massive light gathering for naval watchkeeping, offshore navigation, and deep-space observation. Pairing 10x magnification with colossal 70mm objective apertures, this Porro prism instrument provides a 278.2-foot linear field of view at 1000 yards (92.7m at 1000m), an actual angle of view of 5.3 degrees (apparent angle of 53 degrees), an expansive 7mm exit pupil, and an extraordinary 23mm eye relief for identifying distant channel beacons, maritime traffic, and extended star clusters.

The optical configuration incorporates BaK-4 Porro prisms integrated with Fujinon specialized field flattener lenses and proprietary EBC (Electron Beam Coating) multi-layer anti-reflective depositions achieving 95% total light transmission. Built inside a rigid cast aluminum alloy chassis finished in a classic textured black pebble armoring, the housing measures 25.4 by 9.9 by 28.2cm (10 x 3.9 x 11.1 Inches) and weighs 2.16 kg (4.76 lbs). Built to stringent US military specifications for shock and water resistance, the internal barrels are dry nitrogen gas filled and O-ring sealed for complete waterproof and fogproof protection across temperature extremes from -20C to +50C. Field adjustments utilize individual eyepiece helical focusing collars with integrated diopter compensation, fold-down rubber eyecups, an interpupillary distance range from 56mm to 74mm, and a standard 1/4-20 threaded tripod adapter socket located on the central hinge.

Key Features of Fujinon 10×70 FMT-SX Polaris Binoculars 2022

Designed for professional maritime watchstanders and serious stargazers, this 10×70 Porro prism binocular combines 95% light throughput with edge-to-edge optical flatness. Its field flattener lenses eliminate astigmatism and field curvature across the visual field. The nitrogen-filled military-spec chassis, textured pebble finish, and 23mm long eye relief ensure comfortable viewing and rigid collimation in severe marine squalls and cold night observing sessions.

• 10x magnification power paired with 70mm objective apertures producing a massive 7mm exit pupil
• Porro prism optical architecture incorporating BaK-4 glass blocks for enhanced depth perception
• Integrated field flattener lenses delivering edge-to-edge sharpness with zero astigmatism
• Proprietary EBC multi-layer optical coatings achieving an industry-leading 95-percent light transmission
• Linear field of view of 278.2 feet at 1000 yards (92.7m at 1000m) with 5.3-degree actual angle of view
• Extra-long 23mm eye relief with soft fold-down rubber eyecups accommodating all eyewear
• Built to US military specifications for shock and impact resistance with an all-metal alloy chassis
• Nitrogen gas filled and O-ring sealed waterproof housing operating from -20C to +50C

Field Flattener Lenses & 95-Percent EBC Light Transmission

The 70mm front objective elements utilize rare-earth optical glass treated with proprietary zirconium oxide EBC coatings to transmit 95% of available light. Integrated field flattener lens elements correct field curvature and off-axis aberrations, ensuring stellar pinpoints and distant vessel silhouettes remain sharp across the entire field of view. The large 7mm exit pupil matches the human eye dilated in pitch-black conditions, providing high optical contrast that cuts through ocean haze, coastal fog, and dark sky backgrounds.

All-Metal Nitrogen-Sealed Body & 23mm Long Eye Relief

The cast aluminum alloy body meets US military shock and impact standards, protecting internal prism alignment from rough shipboard handling and engine vibrations. The textured pebble finish provides a secure grip with wet hands or heavy marine gloves. Individual helical eyepiece focusers rotate with precise tactile resistance, allowing observers to set individual eye corrections that remain locked from intermediate distances out to optical infinity, while the 23mm eye relief allows observers wearing glasses or tactical goggles to view the entire panoramic field without vignetting.

• Individual helical eyepiece focus barrels providing precise, drift-free optical calibration
• Submersible nitrogen-purged aluminum alloy body engineered for operation from -20C to +50C
• Extraordinary 23mm eye relief allowing full field visibility while wearing protective eyewear
