$96.00
Binoculars with 10x magnification and 6.5° field of view. The large 50mm objective lenses collect enough light to provide decent relative brightness (25) and twilight factor (22.4) ratings. Such characteristics of the optical system make it possible to use the DELTA optical Entry 10x50 binoculars as a “night” device, allowing you to observe distant objects in low natural light (for example, at dusk). The sealed waterproof housing is filled with gas (nitrogen) to protect the lenses from fogging. The optical elements that make up the Porro prismatic block are made of BaK-4 glass and have a multi-layer anti-reflective coating. The set includes a set of accessories for binoculars: a soft bag-case, a strap and protective covers for lenses and eyepieces.
