Meopta - 10x42 Optika HD Binoculars

A Guide to Birding with Binoculars

Designed to deliver crisp, sharp, and accurate views at long range, the Meopta 10x42 Optika HD Binoculars are built with an array of features, materials, and optical technologies that will make them your constant companion when you're out birding, hunting, hiking, and camping.

Engineered to deliver peak performance in all light conditions, the Optika is outfitted with extra-low dispersion (ED) fluoride glass, anti-reflection fully multi-coated optics, and dielectric-coated and phase-corrected BAK4 roof prisms that work together to maximize light transmission through the entire light path without distortion or color fringing. The results are bright, sharp, and clear high-contrast views with accurate color fidelity and crisp resolution across the entire wide field of view—even in challenging conditions like at dawn and dusk or when peering into dense underbrush or thick canopies. To further improve the observational experience, the Optika is designed with a comfortable eye relief and exit pupil as well as a wide angle of view that minimizes the distracting hand shake that is common with powerful optics to present a spacious field of view.

Meopta constructed the Optika binoculars to make them easy and comfortable to hold and allow them to withstand the elements. The optical tubes are nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging if the weather turns or they take an accidental spill in a stream or puddle. Protecting the optical components is a lightweight and durable magnesium alloy chassis. This gives them the strength they need for constant use outdoors while reducing the overall weight for easier handling and carrying. Ergonomic and slip-resistant exterior armor provides a sure grip. Meopta includes objective lens caps and a one-piece ocular rainguard to protect the exterior lens surfaces. To keep the caps and rainguard safe during use, they are tethered to the body and strap, respectively. For those who experience fatigue when holding large optics for long periods, the Optika can be tripod mounted using an optional adapter for easy hands-free use.

Optical Performance

High 10x magnification enables detailed observations of distant subjects

42mm objective lenses improve light-gathering ability for enhanced low-light performance such as at dawn and dusk or when peering into dense brush

Compact roof prism light path ensures the optical tubes remain slim for easier handling without affecting performance

Extra-low dispersion (ED) fluoride glass lens elements reduce chromatic and spherical aberrations for increased contrast and improved color rendition and sharpness without distortion across the entire field of view

BAK4 prism glass delivers a round exit pupil and a crisp and clear image with limited edge distortion

Phase-correcting prism coatings eliminate internal interference to improve color and contrast

Dielectric prism coatings boost surface reflectivity to greater than 99% for maximum light transmission through the prism with minimal loss and diffraction

Anti-reflection MeoBright fully multi-coated optics boost light transmission to 99.8% to improve resolution, contrast, and color fidelity

MeoShield and hydrophobic exterior lens coatings resist scratches and abrasions while allowing water to bead off without leaving smudges or residue

Wide 60° apparent angle of view presents an immersive and panoramic observational experience

314-foot field of view at 1000 yards

Use and Handling

Closed-bridge configuration provides a stable and strong platform for the internal focusing mechanism

Large slip-resistant center focusing wheel is easy to manipulate in cold and wet weather, even while wearing gloves

±4 right-eye dioptric correction allows user to compensate for optical prescription to produce sharper views

56-74mm interpupillary distance adjustment range enables easy use by a wide variety of users

Twist-up soft rubber-covered aluminum eyecups for durable and easy use with or without eyewear

Integrated tripod adapter mount on front of bridge hinge allow binoculars to be attached to a tripod to reduce arm fatigue and vibrations

15mm eye relief allows for more comfortable viewing with reduced eyestrain, especially during long-duration glassing sessions

4.2mm exit pupil will cover most pupils as they open and dilate in low light to keep the whole scene in view without vignetting

Construction Details

Lightweight and durable magnesium alloy chassis material

Ergonomic body design positions the hand over the binoculars' center of balance for additional comfort and reduced strain and fatigue

Protective rubber armor with textured palm pads provide a solid and secure slip-resistant grip

Nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme changes in temperature and environmental conditions

Tethered objective lens caps and one-piece ocular rainguard protect the lens surface without the fear of losing them when not in use
