Levenhuk 49137 overview

  • 1Description

With a power and objective lens diameter favored by users, plus a wide angle of view and an extremely short close focus distance, the Levenhuk 10x42 Monaco Binocular is built with the avid birdwatcher and hunter or outdoor enthusiast in mind.

It is engineered with highly-reflective dielectric-coated BAK4 roof prisms and anti-reflection fully multi-coated optics, which work together to maximize light transmission through the optical path and ensure bright and clear, high-contrast images with accurate color fidelity across its entire wide field of view. The wide field of view also helps to minimize the appearance of visible hand-shake that is common when hand-holding high-power optics. For those who want to make detailed observations of small subjects like hummingbirds, butterflies, insects, and fauna & flora, the Monaco boasts a short close focus distance of just four feet.

Complementing the optical performance is a lightweight impact-resistant plastic chassis, that is also temperature-resistant to limit the expansion and contraction common in metal chassis that can cause the optical components from moving out of alignment over time. The chassis is wrapped in a slip-resistant rubber armor with textured palm-pads to add grip security and stability in cold or wet weather - even when wearing gloves. Its optical tubes are nitrogen-filled and O-ring sealed to make them waterproof and resistant to fogging when moving through extreme temperature changes. Finally, a large center focusing wheel, ±4 dioptric correction, and twist-up eyecups enable precise focusing and eye relief for just about any user.

Optical Performance
  • Powerful 10x magnification enables detailed observation of objects
  • Moderate 42mm objective lenses maintain a slim form factor while improving low-light performance versus smaller models
  • BAK4 prisms deliver a round exit pupil, and a crisp and clear image with limited edge distortion
  • Anti-reflection fully multi-coated optics produce neutral and accurate color fidelity across the entire visible spectrum, and improve contrast and image brightness
  • 57-layer highly-reflective dielectric prism coatings improve internal reflectivity to maintain image brightness, and improve contrast and color rendition
  • Short 4-foot (1.2m) close focus distance allows detailed observation of small subjects such as birds, bugs, and insects, as well as plants and flowers
  • Wide 65° apparent angle of view helps to mitigate the appearance of visible hand-shake common with high-power optics
  • 342-foot field of view at 1000 yards
Use and Handling
  • Closed-bridge configuration
  • Large textured slip-resistant center focusing wheel is easy to manipulate even when wearing gloves
  • 59-76mm interpupillary distance adjustment range
  • ±4 right-eye dioptric correction
  • Twist-up rubber eyecups for comfortable use with or without eyewear
  • Tripod mountable with optional adapter
  • Comfortable 15mm eye relief
  • Comfortable 4.2mm exit pupil will cover most pupils when they are nearly fully-dilated in low-light, for clear views without vignetting
Optical Performance
  • Lightweight, and impact- and vibration-resistant plastic chassis
  • Chassis is also temperature-resistant to maintain a comfortable temperature in all weather, while resisting expansion and contraction common in metal chassis — that can cause the optics to move out of alignment over time, preventing the ability to achieve sharp focus
  • Nitrogen-filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature changes
  • Slip-resistant rubber armoring provides a slip-resistant grip
  • Textured palm-pads improve grip security
