Leupold 175854 overview

  • 1Description

Sporting large objectives, a high magnification, extra-low dispersion (ED) glass, and the proprietary Xtended Twilight (XT) Lens System, the Leupold 10x50 BX-5 Santiam HD Binocular, in Shadow Gray, delivers bright high-contrast images with true-to-life color and crisp clarity even when observing from long distances.

This binocular is outfitted with a suite of features engineered to complement each other to deliver its performance, including lead-free calcium-fluoride ED glass, the proprietary XT Lens System, plus the Twilight Max HD Light Management System. Image quality is further enhanced through the use of phase-corrected coatings on the BAK4 prisms. The XT and Twilight Max HD systems enhance the already superior light transmission of the glass with index-matched lens coatings that are specifically engineered to raise the already high transmittance across the entire visible spectrum—with special emphasis on the blue and violet wavelengths that are most prevalent in low light. Its large 50mm objectives gather generous amounts of light to further boost performance in less-than-ideal conditions such as at dawn and dusk or when peering into heavy brush.

Designed to stand up to a life lived outdoors, the exterior surfaces of the lenses are treated with Leupold's DiamondCoat2 and Guard-Ion coatings to protect them against scratches and scuffs and allow water and oil to be easily cleaned off—ensuring clear and smudge-free views in all weather conditions. The optical tubes are O-ring sealed and nitrogen filled to make them waterproof and resistant to internal fogging when moving through extreme temperature variations. The chassis is made from polycarbonate to make it lightweight and corrosion resistant. To help further cut weight, while providing you with more area to grip, Leupold employs an open-bridge configuration. Adding even more comfort while in the field, the Santiam comes with an upgraded case and strap that offer maximum protection.

Optical Performance
  • High 10x power brings distant subjects in close for detailed observation
  • 50mm objective lenses help to offset the dimming that often happens when viewing distant subjects at long distances
  • Roof prism light path ensures a slim profile without sacrificing performance
  • Extra-low dispersion (ED) high-definition (HD) lead-free broadband high-transmittance calcium-fluoride glass lens elements produce bright and clear images with accurate color rendition and improved contrast, without fringing
  • Phase-correcting prism coatings eliminate internal interference to improve resolution and contrast
  • Twilight Max HD Light Management System improves color, clarity, and contrast using index-matched multi-coatings that complement the optical glass to ensure maximum light transmission across the entire visual spectrum and enhance low-light vision and contrast; eliminates glare to further improve contrast
  • 58° apparent angle of view approaches wide angle to help minimize the appearance of distracting hand shake that often occurs when holding high-power optics
  • 304' field of view at 1000 yards
Use and Handling

  • Twist-up click-stop rubber eyecups for comfortable use with or without eyewear
  • Tripod mountable with optional adapter to reduce arm fatigue and eliminate distracting vibrations
  • Exceptional 19.3mm eye relief reduces eyestrain for easier viewing, especially during long glassing sessions
