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.
