Nikon 7540 overview

  • 1Description

An ideal companion during long days in the field, on a stand, or at the range, Nikon's black 8x42 Monarch 3 ATB Binocular is engineered for comfort and performance.

Featuring silver-alloy coated and phase-corrected roof prisms with anti-reflection fully multi-coated optics, the Monarch 3 produces bright and clear high-contrast images with accurate color rendition across the entire field of view. Its 8x magnification brings subjects up close, but without the noticeable hand shake often associated with higher power optics, while the 42mm objectives boost its light-gathering ability to improve views in challenging light such as during the pre-dawn and late evening hours or in foggy and cloudy weather. With the combination of prisms, optical coatings, and an exceptionally long eye relief, users can enjoy a comfortable and immersive observational experience in most lighting conditions.

Complementing the optical performance are construction details that make this binocular durable and comfortable to use. It has a lightweight, reinforced polycarbonate ATB chassis and is protected by rubberized armor that is accented with indented palm rests to give it a secure non-slip grip. The optical tubes are nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature variations and environmental conditions. A one-piece ocular rainguard covers the eyecups as the binocular hangs around the neck and prevents rain and spraying water from filling them, and the objective lens caps are also tethered to keep them safe from being lost on the forest floor.

Optical Performance
  • 8x power magnifies objects without sacrificing field of view or exit pupil
  • 42mm objective lenses improve light-gathering ability without adding excessive bulk or weight
  • Roof prism light path ensures optical tubes remain thin for a compact form factor
  • Phase-corrected prism coatings reduce internal interference to improve light transmission, contrast, and resolution
  • Anti-reflection fully multi-coated optics maximize light transmission across the entire visible spectrum for accurate color rendition and improved contrast and clarity
  • High-reflectivity silver-alloy prism coatings reduce internal diffraction to further improve light transmission and contrast
  • 330' field of view at 1000 yards
Use and Handling
  • Closed-bridge configuration provides a solid and stable platform for the internal focusing mechanism
  • Large slip center focus wheel allows for precise focus control, even while wearing gloves
  • Right eye dioptric adjustment collar helps to compensate for individual eye prescription
  • 56-72mm interpupillary distance range allows easy use by a wide variety of people
  • Twist-up/click-stop rubber eyecups for use with or without eyewear
  • Exceptionally long 24.1mm eye relief helps to reduce eyestrain and improves viewing comfort
  • Wide 5.25mm exit pupil will completely cover most pupils as they open and dilate in low light to keep the full scene in view
Construction Details
  • Environmentally friendly Eco-Glass is made without lead or arsenic
  • Lightweight and durable fiberglass-reinforced polycarbonate chassis
  • Chassis material is temperature resistant, preventing the expansion and contraction that is common with metal, which can cause the optical components to move out of alignment over time and prevent sharp focus
  • Textured protective rubber armoring provides a slip-resistant grip, especially in cold and wet weather
  • Indents on the sides of the optical tubes are ergonomically placed where the hands naturally fall for a more comfortable feel in the hand and a more secure grip
  • Nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature changes and environmental conditions
  • One-piece tethered ocular rainguard protects eyecups from water pooling in them from rain or spraying water when hanging from the neck
  • Tethered fold-down objective lens caps prevents losing them during observation sessions
  • Weight: 25 ounces
